RC Battery Care Guide – Safe Charging, Storage & Tips

(Prepared by The Thing Shop)

1. Types of RC Batteries

  • NiMH (Nickel-Metal Hydride) – Beginner-friendly, durable, less maintenance.

  • LiPo (Lithium Polymer) – Lightweight, powerful, longer runtimes, requires special care.

2. Charging Safety

  • Always use the correct charger (LiPo balance charger for LiPos).

  • Never leave batteries unattended while charging.

  • Charge on a fireproof surface, away from flammable items.

  • Use a LiPo-safe bag for added protection.

3. Storage Tips

  • NiMH → Store fully charged.

  • LiPo → Store at storage voltage (3.7–3.85V per cell).

  • Avoid storing batteries in extreme heat or cold.

  • Check batteries monthly if not in use.

4. Voltage Guide for LiPo Batteries

Cell Count Full Charge Storage Voltage Do Not Discharge Below
2S (7.4V) 8.4V 7.6–7.7V 6.0V
3S (11.1V) 12.6V 11.4–11.6V 9.0V
4S (14.8V) 16.8V 15.2–15.4V 12.0V

5. Extending Battery Life

  • Don’t over-discharge LiPos — stop when you notice power drop.

  • Let batteries cool before recharging.

  • Keep packs clean and dry.

  • Cycle NiMH batteries occasionally to maintain performance.

6. Signs It’s Time to Replace a Battery

  • Swelling or puffiness (LiPo).

  • Cracked casing.

  • Cells won’t balance or won’t hold charge.

  • Run times drastically reduced.

👉 Tip from The Thing Shop: The right battery + charger combo is just as important as your RC car itself. Visit us in-store or online for NiMH, LiPo, and smart chargers with expert advice.
