KOOLUX BK6SL1 E-Bike Battery 36V 15.6Ah

BK6SL1 battery 36V 15.6Ah Ebike Battery is a genuine lithium-ion replacement battery for your HITWAY or KOOLUX electric bike, supplied from our UK warehouse.

Each pack uses high-grade 18650 cells with an integrated BMS that protects against over-charge, over-discharge, over-current and short circuit. It locks securely into the original battery base and can be charged on or off the bike.

Before ordering, please match three things on your existing battery: the voltage (36 V or 48 V), the capacity in Ah, and the connector / mounting plate. If you are not sure, send our UK team a photo of the label on your battery and we will confirm the correct pack for your model.
