A Charger Discussion

If you've ever thought about using your lead acid charger to charge your lithium powered battery, you might want to think again. All though the charger can provide charge to a lithium power battery there are some major energy and voltage differences that can be detrimental to your lithium battery. 

Take a look at what Sal has to say about the difference between lead acid and lithium battery chargers:

A charger helps keep the health of the battery for a long time when the battery is out of the bike or not in use. 

Differences Between Lead Acid and Lithium Batteries:

  • Lead Acid Battery is comprised of 6 cells each at 2 volts resulting in a resting voltage of 12 volts.
  •  Lithium Battery is comprised of 4 cells each rated at 3.2 volts resulting in a resting voltage of 12.8 volts

Differences Between Lead Acid and Lithium Chargers:

  • Both lead acid and lithium chargers will charge your batter to 14.6 volts
  • The major difference between these two batteries is how they monitor the state of charge. A lead acid power battery will mimic an elevated level of discharge which can kill the lithium battery since it has a different optimal discharge level. (see graph in the last part of our video.)

When it comes to energy usage and voltage making sure that your battery charger can operate and monitor discharge levels that do not over work and break your lithium powered battery.
