Our 52V Competitor battery pack is comprised of Molicel P42A cells, and is designed specifically for high power and high speed. A specs comparison chart is below. Please note that you must use a 52v (14s) nominal l-ion charger with male XT60 connection for this pack (see here).   

All our battery packs are carefully spot-welded using .3mm pure nickel connections, with a bms for balance on charge and discharge. They are then fully potted with Epic Resins S75253 thermal epoxy to isolate each cell a minimum of 2mm from any neighboring cell or surface, and encased in aluminum for high heat dissipation, fire-propagation resistance, shock absorption, and water resistance (read all about it here). Handmade in Los Angeles, our battery packs are arguably the toughest and most high-performance batteries of their size.   

All batteries are made to order. Please allow two to four weeks for delivery.
