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 an
EC5, XT60, or T- 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. Always include a 40A auto blade fuse in both the red and black discharge leads or purchase
REVO PN: PN: CP8S-SBP18-40A which already includes the fuses and solder on the mating end of the
connector attached to your battery pack. Alternatively, consider one of the Revolectrix MPA or MPA-4P
which vasty simplify the interconnections and allow safe parallel charging. See Parallel Charging below
for details. Visit http://www.revolectrix.com/adapters.htm

The PowerLab Touch balance port accepts direct connection of a universal JST-XH balance connector up to
the max cell count supported by the model (9-pins on 8s models, 7-pins on 6s models). To connect a pack
lower than the 6s or 8s max cell count, 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 PowerLab Touch series does not support balance-wire-only charging.
WARNING: Failure to comply with the above could result in fire and/or
damage not covered by warranty!
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.
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.
Note: Best practice is to connect balance connector first, then connect
discharge wires.
