The AMP E-Bikes 48V 21Ah battery is our best budget option for riders who want reliable performance without compromise. We love that it gets more people into electric riding — combining affordability with the same high-end design principles used across our premium range. Though this is our lowest-capacity model, no time, design, or expense have been spared. Every pack is built for efficiency, safety, and long-term durability, making it a true high-quality performance battery built to last.
Housed in a compact, heavy-duty shell, the 48 V 21 Ah battery is lined with 360-degree heat-resistant silicone foam that provides complete vibration damping and superior thermal stability. Certified to UN38.3 vibration and IPX7 waterproof standards, it delivers dependable performance in all environments.
Inside, fire-resistant fish-paper insulation separates the balance and signal wires from heat and abrasion, while precision-moulded cell holders ensure correct spacing for airflow, cooling, and structural integrity. At the core, silver-plated copper busbars and laser-welded connections achieve ultra-low resistance and up to 95 % efficiency under heavy load.
The smart 50 A BMS continuously monitors performance, balancing cells, regulating temperature, and providing complete protection against over-charge, over-discharge, over-current, and short-circuit conditions. With a cycle life exceeding 1 000 charges, this pack delivers consistent, long-lasting reliability. Finished with a 5V USB output for convenient device charging, it pairs perfectly with AMP’s 1000 W – 1500 W kits, typically providing an estimated range of 25–35 km, depending on terrain, rider weight, and power settings.
