Featuring an AC function and a separate corresponding balance port for each battery pack, it is particularly well-suited for RC cars and helicopters.

Warnings:
Observe any cautions and warnings included with your battery.
Never leave the charger unsupervised during use. If any malfunction is observed, immediately terminate the process.
Keep the charger away from moisture, dust, dirt, heat, direct sunlight, and vibration. Do not drop it.
Double-check all connections prior to starting the charging process. Do not connect with reverse polarity.
The charger and the battery to be charged should be placed on a heat-resistant, non-flammable, and non-conductive surface. Never place them on a car seat, carpet or similar. Keep flammable and volatile materials well away from the operating area.
When charging LiPo batteries, we suggest using a LiPo charging safety bag, available from most hobby retailers.
Never charge a LiPo battery that is swollen in any way.
To avoid short-circuits between the output power adapter cord input connectors, always connect the adapter cord to the charger first and only then to the battery to be charged. Reverse the sequence when disconnecting.
