Just want to see if anyone else has woes with this battery, It's my 3rd one, first I bought a 4cell for my kick only and haven't installed it. I have an electric start pan, put a 12 cell which is no chump change and thing almost burned my whole bike, then I went with a 16 Cell, again no chump change either, almost 1k in batteries last year, the thing dies, I send back to company, they re-charge it and now it's dead again, it happened over the winter, I would start it up for a couple of mins every month for about 3 months. Dead, dead, dead, is there another battery out there that is small enough to power an electric start pan, 74? I can't see myself waist anymore money, if that's the case I will just kick instead, please someone give me some comforting input.

I don't have comforting input. I've seen lots of people have problems with them. I swore it was them doing something wrong, wouldn't happen to me so I married myself to one on my build. I'm on my second one as well.

My story:

- Bought a 4-cell for kick-only setup
- Read that you can't let the voltage drop below 11v
- Build was taking awhile so at 6mo bought a charger from them for LiFEpo batteries
- Tested voltage periodically and charged it when it finally dipped below 13v
- Got the bike running a few months ago and one day the thing inexplicably failed (<2000 miles on the build)
- Wasn't reading ANY voltage
- Wasn't reading ANY resistance between the pos/neg terminals (hmm.. busted circuit inside?)
- Wouldn't charge (obviously... battery charger/tester said the battery was broken)
- Sat on the bench overnight and went to show the same thing to a friend and magically, it registered voltage and resistance
- Called them up about their "24 month warranty" and was told they'd have to test it and the warranty is pro-rated
- They offered me 20% off retail MSRP (i.e.... more than it sells for in the wild) IF they would cover it
- Said f-you and replaced it with a spare (I'm anal and since the thing weighs only 1lb, not a bad idea to carry a spare for road trips so I had one anyway)


Still haven't replaced my spare but will do so when spring hits. Fuck them and their warranty I say. From what I've seen, these lithium batteries just can't handle the vibes of a rigid chopper. No other explanation.

Also, my charging system is in tip-top shape (brand new Cycle Electric validated routinely during break-in of the bike). My wiring is as bare bones as can get. I don't have any shorts, etc. I'm as anal as can be about electrical and I have an EE degree.


Good luck. :)

I went through a few. Customer service is really good, but I gave up on them because you cant just through them on a charger somewhere if they die, or go to the store and replace them. Went back to Harley ones for convenience.

I had one quit. Was completely dead one day for no reason, and won't take a charge. Bought another one, working longer than the first. Couple buddies had about the same issue.

I had one in a bike. It would be fine for weeks on end, and then dead. Recharge and it might be good for a day, a week or a month. Just randomly it would discharge. Sold the bike with it in it so no idea how it played out

On my race bikes I have been running a Shorai and I love that battery. One race bike has a Odyssey and that is a bad ass battery too, but it isnt small like the Lipo/Life's

Didn't seem to make any difference if the bikes were run all the time or just once in a long while.

No surprise, we got one for a build, that had a odd battery placement. thing worked for one ride only. They would not exchange it etc.
My hurt, never tried another one. Might be rigids beat them up too much. Nice idea, just did not work out.

Jesus, I've had my Ballistic 6 cell for 2 years (electric start) never had to charge it and it still fired up after sitting in the bike for 2 months with temps as low as -20

My buddy ran a ballistic in his road rally car- thing blew up on him. I don't trust these LiPo/LiFe batteries.

I must be the only one that hasn't had a problem with it. 99 Sportster with points. Just headlight, taillight, starter, and ignition.

I've shorted it out a few times and it would just not work for a bit then start working fine again. I just figured it has some kind of internal fuse or something. Once my key switch broke and it shorted everything out. The other time I was putting my seat back on and pinched the wire.

I rode the bike all summer and put thousands of miles on it with no problem. Oh, and the bike doesn't have a single fuse on it. I'm going to be putting a few fuses on when I get it rebuilt this week.

When them things first hit the market, I remember reading that they needed a specific Regulator/Rectifier to charge properly. When did that change?
You are supposed to buy a lithium specific tender, right? Are we just ignoring the manufactures' recommendations?
Can't tell you how many times I've seen people fill and charge a lead acid battery the wrong way (shortening it's life and minimizing its cca). The little book that comes in the box spells it out for you. What did the little book that came with those failed lithiums say??
I think some of them have onboard circuitry to deal with voltage spikes and change the square wave to a round wave or some such oscillator mumbo-jumbo.
Any electrical engineers want to chime in on the specifics?

The tech needs to grow up a bit, still teething.
And the industry needs to stand behind it's product and take lessons from the real world, not ignore feedback just because it's negative.

I just charge mine with my regular charger if I run it down. Only happened twice when fooling with carbs. I don't even put a tender on it. I just ride it a lot.

Charging system is working perfectly. I've got a 30amp breaker between the reg and batt. Anti gravity is telling me there is no way their battery can do this on its own. Even if my reg was overcharging the breaker would have popped before the battery caught fire.
Battery has been on my bike for 3 months. Never touched a charger never dipped below 12v. Now my seats toasted, oil bag has half a battery cement melted to it and ive got to shell out more money for another one of these spontaneously combusting plastic bombs? I wish we wouldnt had made the oil bag specifically for an anti gravity sized battery.

Havn't had a bit of trouble out of either of my lithiums..my only complaint is that on a cold morning they are a little weak..A lithium only has to have the special charger if you let it run down..low , like 8 volts..They say it will damage it if it runs down below 7 volts..The reason for the special charger is that each cell runs down differently, and they all have to be charged back up together..As long as the battery has a decent charge on it then you are ok to put a regular charger on it ..for a while..you wouldn't be able to run it in the bike otherwise.Don't ever drop a completely dead lithium in a bike and run it..They say you can do it with the Scorpion though ..Lets face it where are you going to hang a gigantic lead acid battery on a chopper..? unless you make some kind of cool looking saddle bag to put it in like I did on my Shovel chop.

Fuck batteries. Install a magneto and do away with the battery, coil, half the wiring, fuse boxes and all the bullshit. Never worry about a battery dying. I know the mags are expensive, but you guys who have burnt up 3 or 4 anti gravity batteries threw away money that could have paid for a mag.

RetroRob

I know all about the 4 cells, had a number of them. If they get under 10volts might as well throw them away unles you have their charger.
I killed two on my pan until I figured out the led bulb in my tail ligh was causing a parasitic drain. Went to old fashioned bulb an all is well

The price on these things is INSANE! I buy a good battery ( about $ 100.00) ALWAYS put it on a battery tender when I get home, And always get over four years out of them. The battery is still working when I replace it but I just get paranoid as I get near the 5 year mark. Why mess with this crap??!! ( I usually buy Powerhouse or Scorpion batteries.)

Capacitors...get six or eight 250mf caps. Solder them in series. Boom..I've been running them in my bikes and cars for years. Cant remember the last time I bought a battery.

Salty

They sent me a replacement free of charge seeing as i had only had the battery for 3 months. Ive checked and rechecked voltage at the battery under load and it wont go over 13.66. My question, how did i smoke the first battery if its not even reaching 14 volts?

do all LED lamps leak current I wonder? My Anti gravity battery crapped out
about a year ago & I am wondering if my LED tail light was the cause, I purchased
a lithium charger and keep a close watch on the battery voltage because like You
said, 10 volts is the lower limit or these lithium batteries.

Shovel52
04-21-2016, 7:21 AM
are you asking if an led leaks current when there is no power applied, key off? no..an led is just a diode, a diode can short but that
would effect the others in a tail light. and it wouldn't be enough to run a battery down when the bike is running. Do all of them light up? The answer is no , I would eliminate the taillight from the problem..

i got mine in new just the other day. bought it for no other reason than i got tired of hooking up to a charger. hooked it up and it tried to crank for about 2 seconds and died.....dead as a door nail. even my old worn out battery that i paid $80 lasted a year and would have lasted longer if i would have rode more the charge it......not impressed...wish i would have seen this sooner also

I had the battery mounted lightly snug with foam on either side.
First season using it about a month in.

I drained the battery a few times when I was first shaking the bike down. I would pop it out and charge it off my secondary battery in my car for about 10 to 20 min. Did this three times or so no problems.

The other day battery starts to die out of the blue not sure why. Then eventually it wouldn't turn the bike over. Sort of lazy to take the battery out this time as it's a lot of work so I managed to get some small aligator clips to the posts with out unhooking anything and again wired it to my auxiliary battery in my car. In about one minute I could smell something like hair spray and I look over and battery is a raging inferno.

Not sure if I did something wrong? I know you aren't supposed to let it go flat or give it a boost ect. I never killed it flat for any amount of time. I herd letting an alternator tickle it back to life under emergency was supposed to be sufficient.

So many stories about these things catching fire though I'm not sure if I did something to cause this or its just the common problem with these but either way that's my experience.

I don't plan to repurchase one.

I will never jump a bike off a car. Too much!

Anti's call for a specific charger as well. You done fucked up boy. Dont tell them you did any of that and they may give you a replacement free of charge.

From their site:
"You should NOT use an automobile or motorcycle charger that is specific to Lead/Acid batteries! They can cause damage to the batteries because they charge in a different way than a specific Lifepo4 Lithium Charger. They often have a Desulfinate feature or over voltage “Quick Charging” feature - both of which will damage the Antigravity Battery. Lead Acid chargers in many cases will overcharge a lithium battery ending up in damage which is not covered under our warranty."

Warranty Does NOT Cover Any of the Following Physical and Installation Issues:

Any physical damage caused by abuse, misuse or improper installations.
Any modification to any part of the battery or its parts.
Physical damage to battery after purchase by impact, neglect, or misuse.
Installations in Custom Crafted Vehicles using other than stock charging systems.
Installations in “Oil Bags” (this is too high heat for a battery to survive, and dangerous).
If the battery is used in sanctioned competition… “Race”… use of any kind.
If the battery is used in a manner for which it was not intended.


Warranty Does NOT Cover the Following Electrical Issues

Damage from “short-circuiting” of the battery
Damage occurring from faulty Voltage Regulators (overcharging of battery by vehicle).
Custom installation using aftermarket or performance electrical parts such as Stators, Regulators…
Using a Battery Tender or similar Lead/Acid type Maintainer/Charger product on the Antigravity Lithium-Ion Battery (do not use Lead/Acid type chargers).
Use of Chargers NOT intended specifically for Lifepo4 Lithium Batteries with a maximum charge voltage not over 14.4V
Over-Charging/Over-Discharging due to a defect with vehicle’s voltage regulator or defective or non-compliant charging system on the vehicle.
Over Charging battery above 14.6V
Over Discharge of battery below 9.8V
Allowing voltage to drop below 9.8V by lack of vehicle maintenance or monitoring.
If the Battery is used for an application that requires higher cranking poewr or a greater reserve rating than the Battery is designed to deliver, or the Battery capacity is less than the Battery capacity specified by the vehicle manufacturer, or the Battery is otherwise used in applications for which it was not designed, such as “Total-Loss” systems.
Parasitic drains that discharge the battery to below 9.8V

The 3-Year Limited Warranty is pro-rated based from the original date of purchase. Only ONE battery replacement will be given under warranty.

1-6 Months: Free Replacement
7-15 Months: 75% discount from retail MSRP
15-24 Months: 50% discount from retail MSRP
25-36 Months: 25% discount from retail MSRP

I didn't boost it. IE hook it up then crank it. I hooked it up to my cars secondary battery and let the alternator recharge it enough to fire the bike after it was disconnected.

The problem with the Internet is everyone is an expert on everything. Here's the link to where I read to tickle the battery back to life in that manner;

Not to be installed in oil bags is a huge WTF.

My anti-g battery just took a crap a few days ago, It was a
free (warranty) replacement they gave me when I drove over to their facility
a few months ago, not again. Fuck these batteries.

Scary to read all this crap but I have never had one issue with antigravity battery have any of you guys use the foam around the battery to insulate it so it doesn’t have direct heat contact from the oil bag ? I have been using that on my knucklehead and pan shovel and have had zero issues. It keeps it from vibrating and also protects it from the direct heat. I have been using the 8 cell on generator driven motors and even my generator a couple times have taken a shit and still no problems.

I wouldn't put a small battery in there your just asking for problems.... Now if it was a kick only then you could go small.. But if you have your heart set on a small battery what is the size of the hole do you have to put the battery in??? Batteries come in all sizes...
