48V 21Ah Li-ion Battery — S10
The S10 is a 48-volt, 21-ampere-hour lithium-ion battery designed for reliable, everyday power — good for e-bikes, scooters, backup power, and small off-grid systems. It balances long run time with a compact form factor and built-in safety to give you predictable performance without fuss.
Benefits
- Go farther between charges — higher usable capacity means fewer interruptions during trips or tasks.
- Reduce downtime — faster recharge and stable output help you get back to work or riding sooner.
- Feel safer and more confident — integrated protection reduces risk of overcharge, overdischarge, and short circuits.
- Simplify installation — a compact, mountable pack that fits common frames and enclosures.
- Spend less on replacement power — efficient chemistry gives more usable energy per kilogram than older battery types.
Features
- 48 V nominal lithium-ion chemistry for consistent voltage delivery.
- 21 Ah capacity providing approximately 1,008 Wh of energy.
- Onboard Battery Management System (BMS) with overcharge, overdischarge, and short-circuit protection.
- Cell balancing to maximize usable capacity and extend cycle life.
- LED charge level indicator for quick status checks.
- Standard charge port compatible with common 48 V chargers.
- Mounting points and a handle for secure installation and easier carrying.
