This helps simplify charging and provides useful information for maintaining your battery.
⚠️ Charging Note:
A compatible Spektrum Smart charger is recommended to access Smart features and automatic charging setup. Always use a charger that supports NiMH batteries and follow the manufacturer's charging instructions.
Charger sold separately.
💡 Pro Tip:
A 7-cell NiMH battery provides 8.4V nominal voltage, compared with 7.2V from a traditional 6-cell NiMH pack. For compatible brushed RC vehicles, that additional voltage can provide a noticeable performance boost while maintaining the simplicity of NiMH battery operation.
