AMP E-Bikes 52V 21Ah battery is one of our best-value options, offering exceptional performance for its size and price. It stacks up closely to our larger 30 Ah models thanks to its highly efficient design and the integration of new technology and cells maximises energy output while minimising heat and loss. The battery is housed in a compact yet heavy-duty plastic shell, lined with 360-degree heat-resistant silicone foam that provides full vibration damping and superior thermal stability. Certified to UN38.3 vibration and IPX7 waterproof standards, it delivers consistent reliability in every environment.
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 and long-term structural integrity. At its 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 provides real-time monitoring and complete protection from over-charge, over-discharge, over-current, and short-circuit conditions, while balancing cells and managing temperature for optimal lifespan. With an impressive cycle life exceeding 1,000 charges, this pack delivers lasting reliability. Finished with a 5 V USB output for convenient device charging, it pairs perfectly with AMP’s 1,500W – 2,000W kits, typically provides an estimated range of 45km, depending on terrain, riding style, and motor power settings.
