when the battery is fully charged or when the first cell reaches peak
voltage. Depending on the battery, this may reduce the charge time
by a few minutes.

WARNING: FIRE HAZARD!

The fast charge LiPo setting is for occasional use only. LiPo
batteries that become severely out of balance over time can

create a hazard if one or more cells are discharged below
the recommended safe voltage during use. See additional
warnings and precautions in the beginning of this manual.

Balance Charge (recommended)

Always balance charge your LiPo batteries for maximum capacity,
voltage, and battery life. This is the default setting for Traxxas iD
batteries. The EZ-Peak Live performs a balance charge quickly and
efficiently.
