CAUTION: When two LiPo packs are connected in series, do not connect them to two
separate chargers that are wired to a single power source. This sets up the dangerous
condition in which the series-connected packs are being charged in parallel (the power
source provides a common ground). One or both chargers, as well as the packs,
will be damaged. This condition will be avoided if the chargers are driven from two
unconnected power sources (e.g., two lead acid batteries). For safest charging of
series-connected packs, disconnect the packs from each other before connecting them
to chargers.
Connecting non-Cellpro packs
FMA Direct offers plug-and-play adapters for charging LiPo packs equipped with node con-
nectors made by other vendors. Check the Cellpro section at www.fmadirect.com for the lat-
est adapters.
If an adapter isn’t available for the pack you want to charge, or if the pack doesn’t have a
node connector, the FMA CPBP7 LiPo Pack Node Connector cable assembly will make the
pack compatible with the Cellpro 4s Charger. The diagrams below show how the Node Con-
nector attaches to packs of various configurations. Additional assembly information is pro-
vided with the Node Connector.
