About the Cellpro 4s Charge Protection Module
The Cellpro 4s Charge Protection Module (CPM) protects FMA Cellpro Battery Packs from
overcharging during charging from a non-Cellpro charger. Cellpro Packs have special connectors
that enable the Cellpro 4s CPM (as well as Cellpro 4s Discharge Protection Modules) to monitor
the voltage of individual cells within the pack.
During charging, the Cellpro 4s CPM monitors cell voltages and disconnects the charge current
when the first cell reaches 4.2V. This extends pack life by preventing overcharging.
Features

Works with any standard LiPo charger.
 Handles up to a 4s Cellpro Pack.
Three Cellpro 4s CPMs can be daisy-chained to handle up to 12 cells in series.

 Connects to charger through Deans Ultra connector.
 Integrated LED provides status information.
Precautions

Follow all instructions in this manual to assure safe operation.
 Before charging through a Cellpro 4s CPM, allow packs to cool for one hour. During dis-
charge, inner cells become hotter than outer cells. If a pack is charged when hot, cells will be
damaged because their different temperatures result in different charge rates.

Always watch LiPo packs while they are charging. Never leave LiPo packs unsupervised dur-
ing charging.

Follow all LiPo charging precautions, as listed in the warning sheet provided with FMA LiPo
packs, including charging packs in a fireproof container and monitoring the entire charging
operation.
