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.
