The BT-E8036 is a genuine 630Wh battery for STEPS e-bikes, designed to sit integrated inside the frame's down tube. It's the high-capacity option in the integrated range, so it's a good choice if you want to replace a tired battery or add a second one for bigger days out.

At 36V and 17.5Ah it has the capacity for long rides on Shimano's mid-drive systems, and it's built to hold more than 60% of its capacity after 1,000 charges. A full charge takes around 4.8 hours with the EC-E8004 charger, or about 3.2 hours to reach 80%.
