Introduction
A good battery charger is just as important as the batteries themselves. The right charger charges your batteries safely, extends their lifespan, and gets you back in the air faster. The wrong charger – or the wrong settings – can damage your batteries or create safety hazards. With the wide range of chargers available from Gens ace and Tattu, how do you choose the right one?
Understanding Charger Specifications
Wattage
Wattage determines how quickly a charger can charge your batteries. Higher wattage means faster charging. For example, charging a 6S (22.2V) battery at 5A requires 22.2V x 5A = 111W. If your charger is only 100W, it can’t deliver 5A to a 6S battery.
AC vs DC Input
- AC Input:Plugs directly into a wall outlet. Typical AC chargers range from 60W to 1000W.
- DC Input:Requires an external DC power supply. Allows for higher wattage – up to 9000W.
- AC/DC Dual Input:Supports both, offering maximum flexibility.
Channels
- Single Channel:Charges one battery at a time
- Dual Channel:Charges two batteries simultaneously
- Multi-Channel:Charges 8 or more batteries
