Lithium Motorcycle Battery Dead

If your bike produces less than that because of a tired charging system the lithium battery will not charge and it will ultimately run out of juice leaving you high and dry.

Lithium motorcycle battery dead. Lithium battery failures the technology has advanced enough to include battery management systems bms which balance the discharge and recharge loads. Lifepo4 is all but dead at 9 5v. Bms shuts down the battery if an overcharge is detected to prevent overheating and the potential to catch fire. You can check the age of the battery pack and measure the voltage if able or check for date codes on the circuit board inside.

But it s not recommended to drop below 12 85 20 for max life. Lithium ion cells don t like to be discharged below their over discharge voltage usually between 2 5 and 2 75 volts at the most. Remember usb is only 5v so your dead li ion battery needs to be rated under that. It may not recover and or lose it s rated ah capacity.

However many li ion battery systems on the market are made from large prismatic cells connected to an external management system. So yes a dead battery pack may be jump started by simply applying a charging voltage until the cells regain an appropriate voltage allowing the battery management system to reconnect for discharge. A lithium iron motorcycle battery is very light and is supposed to hold a charge for a very long time but if you re lithium iron motorcycle battery goes dead you can use a car battery charger set. Most of the time these batteries will be dead and i mean dead.

If your lifepo4 battery has stayed at low voltage for very long. What hurts batteries of all types is staying dead for very long.
