Transmitter Battery
When purchasing a transmitter battery use the following:
Part name
HT5F1800B (6V/1800mAh) NiMH battery
FT2F1700V2(6.6V/1700mAh)/2100BV2 (6.4V/2100mAh) LiFe battery
Please do not use the transmitter batteries HT5F1800B and FT2F1700V2/2100BV2 as the
receiver's battery.
Since the transmitter's battery has an overload protection circuit, the output power will be
shut down when the high current load is applied. This may result in runaway or fatal crash.
