E-Bike Batteries

Ebike Essentials stocks 48V and 52V lithium packs for Bafang mid-drive and front-hub conversions, from compact Dolphin packs up to the 1,176 Wh Whale Shark. Every pack ships with its mount, keys and a matched charger, and each product page lists watt-hours, dimensions, weight and a defensible range estimate.

Not sure what fits? Battery choice depends on your frame space and your motor's voltage — run the fitment checks or browse complete kits with a battery included.

Replacing an existing pack? Most riders replacing a worn e-bike battery need to match three things: the pack voltage, the connector, and the case shape their frame mount accepts. Our packs use Anderson connections and are built for Bafang kits — check your existing pack's voltage and measure the frame space before ordering, and send us your bike details if you are unsure. Cells lose capacity with age, so a replacement will usually out-range the pack it is retiring.

Which voltage? Both Bafang mid-drive kits (BBS02 750W and BBSHD 1000W) run on either 48V or 52V — a 52V pack delivers more peak power from the same motor. Front-hub kits use 48V. Whatever you choose, the charger must match the pack voltage; our kits pair them automatically.

How far will it go? Range depends on rider weight, terrain, assist level and speed. We quote a band of 13–24 watt-hours per mile, so a 672 Wh pack is roughly 28–51 miles and a 1,176 Wh pack roughly 49–90 miles.
