Under 10 volts can kill the battery. Over 15 volts can kill the battery. A standard battery charger can kill the battery. Did you get a correct style charger with the bike/battery?
...On the other hand, if there was an issue with the installation or the maintenance of the battery or vehicle, such as allowing
the battery to Over‐Discharge below 10 Volts, a faulty Voltage Regulator leading to over‐charge, an incorrect charger was
used, if it was installed in a way that could lead to short‐circuiting, or other potential issues beyond our control, then that is
an issue we cannot be held responsible for. <snip>
...Below are the common causes of damage to your Antigravity Battery. Please make sure to note them. These conditions/situations
WILL damage your battery or in extreme cases and conditions there could be a potential for Fire or Explosion!
Over‐Charge due to faulty Voltage Regulator‐ This usually happens on older Harleys, or Older 60s‐80s bikes due to defective Voltage
Regulators… The Voltage Regulator is old and then goes bad creating a large spike in voltage charging the Lithium Battery. The tell‐
tale sign of this is a “puffed” battery … the battery become physically distorted and ballooned by overcharging. In worst case
scenarios the battery can be over‐charged to a point that causes a meltdown (thermal runaway) of the battery and potential for fire.
So please make sure your electrical system is operating correctly and not over‐charging at any time over 14.4volts. Often time After‐
Market charging systems are not regulated as a stock system is, be aware of this if you use and aftermarket charging system.
WARRANTY DOES NOT COVER THE FOLLOWING ELECTRICAL RELATED 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 product on the Antigravity Lithium-Ion Battery (do not use Lead/Acid type trickle 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-complaint 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 maintenance
