Connecting Packs
General info
When balance charging, both a balance connector and the main discharge wires must be
connected.
When performing a non-balance charge on a LiPo, LiFePO4 (or A123), NiCd, NiMH, or
Lead Acid pack, connect only the pack’s main discharge wires to the two outer banana
jacks of the charger.
Pack discharge wires are usually not terminated in banana plugs (e.g., they might be
terminated in a Deans connector). For convenience in connecting to the charger, prepare
an adapter cable with banana plugs on the charger end and a connector that mates with the
pack’s discharge connector on the other end.
The GT1000 balance port accepts direct connection of a universal JST-XH balance
connector up to 7-pins, supporting packs up to 6s. To connect a pack lower than 6s, align
the connector to the right as shown. The negative pin of the battery pack balance connector
(usually identified by a black wire) must be connected to the ground of the charger balance
port (identified by an arrow or “GND”) in all cases.
The GT1000 does not support balance-wire-only charging.
Note: After a charge is initiated, never alter the connections between
the charger and the battery packs. Always end the current charge
session before making any connection changes. See page 25 for
more information about STARTING and STOPPING charge sessions.
CAUTION: When using the banana plug adapter cables described
above, ALWAYS insert the banana plugs into the charger BEFORE
connecting the adapter cable to the pack. Reverse the sequence
when disconnecting the pack. This will prevent the live banana plugs
from touching each other, which would create a dangerous condition
and could seriously damage the pack.
