Which RC vehicles does it fit?
- Designed for NQD 1:14 remote control monster cars and DE68, DE44, DE45W, DE42 remote control trucks, as well as water guns.
- Because it is larger than typical 500–800mAh batteries, confirm the compartment can hold 66x18.5 mm cells.
Charging the battery
The included USB cable has a built-in overcharge protection circuit that stops charging when full. A red LED indicates charging; when the red LED turns off, charging is complete. Some units may not turn off the LED; if that happens, reconnect the charger. The 0.8A rate charges faster than 0.5A chargers.
Will this battery fit my RC car?
Measure your existing battery: it must be no larger than 66 mm in height and 18.5 mm in diameter. The SM-2P plug must match your vehicle’s connector. If your current battery is a 3.7V 500mAh cell, this replacement is thicker and longer, so the compartment must have extra space.
