Safety primer: charging math, storage, and parallel basics
- Know your power math: Charger power (W) = pack voltage (V) × charge current (A). Example: a 6S LiPo is about 22.2–25.2V; charging a 6S 5000mAh at 1C (5A) needs roughly 125W–130W plus overhead. Two such packs simultaneously can push past 250W, so a 300–400W charger (or higher) provides comfortable headroom.
- Storage voltage matters: Keeping LiPos at ~3.80–3.85V per cell when idle reduces puffing and extends life, as explained in the Horizon Hobby “How to charge RC batteries” guide (2024/2025).
- Temperature and 1C: For longevity, 1C is a good default; reduce current if packs feel warm. Practical tips and rationale are covered in the Oscar Liang LiPo battery guide (2025 update).
- Parallel charging: Only parallel packs of the same cell count and similar voltage; double-check polarity and use quality parallel boards. Keep a fire-safe setup and monitor closely.
- Recall awareness: Avoid known-problem models and periodically check the 2025 U.S. CPSC recall for HTRC C240 chargers.
FAQs
AC vs DC: Which should I buy?
- Choose AC/DC if you want plug-and-play convenience at home without a separate power supply. Many AC modes are power-limited.
- Choose DC-only or DC-capable if you plan to parallel charge or run higher rates. Pair with a quality DC PSU or field battery to unlock full wattage.
What size charger for 6S 5000mAh packs?
- At 1C (5A), a single 6S typically needs about 125–130W plus overhead. For two packs concurrently, plan 250–300W minimum. If you want 2C charging, double the watts requirement. Leave 20–30% headroom so the charger isn’t running at its thermal limit.
Is parallel charging safe?
- It can be when done correctly. Only parallel packs of the same cell count and with similar state-of-charge; verify balance leads and polarity; use a quality board; never leave the setup unattended; keep a LiPo-safe container nearby.
Next steps
- If you’re upgrading your entire power ecosystem, make sure your connectors, parallel boards, and power supply match your chosen charger.
- For teams or clubs, consider one high-power DC station plus a smaller AC/DC unit for flexibility.
