Rated 4.9 out of 5 stars.
If your electric bike's battery is dying too quickly or won't hold a charge anymore, this 36V 13Ah replacement pack could get you rolling again. It's a lithium-ion battery, which is standard for modern e-bikes. The 13Ah (Amp-hour) capacity is a good mid-range size, offering a decent range per charge – how far you get depends on your motor power, assist level, and terrain. It's compatible with common 36V systems and motors rated around 250W, 500W, or 750W. The physical size is 390mm x 110mm x 75mm, so you need to check it will fit in your bike's battery compartment or mounting bracket. It comes with a matching 42V 2A charger. Safety features are built-in via a BMS (Battery Management System) that protects against overcharge, over-discharge, short circuits, etc. It has a long cycle life (over 1000 charges if treated well). The discharge port is either 2-pin or 4-pin – you need to make sure it matches your bike's connector. If you're not sure about compatibility, contact the seller with your bike model before buying. A cost-effective way to extend the life of your e-bike instead of buying a whole new one.
