Important warnings for users of Lithium Polymer
(LiPo) batteries:
Lithium Polymer (LiPo) batteries are significantly
more volatile than other rechargeable batteries.
• ONLY use a Lithium Polymer (LiPo) balance charger
with a balance adapter port to charge LiPo batteries.
Never use NiMH or NiCad-type chargers or charge
modes to charge LiPo batteries. DO NOT charge with
a NiMH-only charger. The use of a NiMH or NiCad
charger or charge mode will damage the batteries
and may cause fire and personal injury.
• Never charge LiPo battery packs in series or parallel.
Charging packs in series or parallel may result in
improper charger cell recognition and an improper
charging rate that may lead to overcharging, cell
imbalance, cell damage, and fire.
• ALWAYS inspect your LiPo batteries carefully before
charging. Look for any loose leads or connectors,
damaged wire insulation, damaged cell packaging,
impact damage, fluid leaks, swelling (a sign of
internal damage), cell deformity, missing labels, or
any other damage or irregularity.

LiPo (Lithium Polymer) batteries
are made from stacks of flat
rectangular cells so the battery
pack is rectangular, blocky, and has
square corners. LiPo batteries also
have balance connectors. For older Traxxas batteries
with first generation High-Current Connectors, the
balance connector and the multi-colored balance
wires are separate. For Traxxas iD batteries, the
balance wires are integrated into the High-Current
Connector (see Know your connectors on page 6).
NiMH (Nickel-Metal Hydride)
batteries are constructed using
6, 7, or 8 round battery cells that
are soldered together and and
wrapped with heat shrink material.
NiMH batteries do not have a
separate balance wire.
Know Your Batteries
The EZ-Peak Plus® 4s is able to charge two different types (chemistries) of batteries: NiMH and LiPo.
Batteries are normally clearly labeled, but they can also be visually identified as a confirmation step.
