SM-2P USB Charger Cable – 3.7V Li-ion/NiMh RC Toy Battery
SM-2P Universal USB Charging Cable for RC Toys & 3.7V Batteries
Keep your RC toys and small devices powered up and ready to go with the Skerimte SM-2P Universal USB Charger Cable. Designed for Li-ion, NiMh, and NiCd batteries, this intelligent charging cable uses IC (MCU) pulse-controlled technology for faster, safer, and more efficient charging than traditional USB cables.
Made in Mainland China.
Smart Charging Technology
Unlike basic USB cables, this charger employs intelligent pulse charging — alternating charge cycles that actively monitor battery voltage throughout the process. This helps extend overall battery lifespan and ensures a balanced, even charge every time.
Built-In Safety Features
- Input overvoltage protection – guards against power surges
- Output short-circuit protection – prevents damage from wiring faults
- Reverse battery protection – safe even if connected incorrectly
- Auto stop when fully charged – no overcharging, no babysitting required
Easy-to-Read LED Indicator
The two-color LED makes it simple to monitor charging status at a glance:
- 🔴 Red light solid – Power connected, ready to charge
- 🟢 Green light flashing – Charging in progress
- 🟢 Green light solid – Charging complete
- 🔴 Red light flashing – Battery fault detected
