Surron 72v Battery Upgrade Guide
Sur-Ron 72V Battery Upgrade Guide: Best Packs for the Light Bee X
A 72V battery upgrade is the single biggest performance modification you can make to a Sur-Ron Light Bee X. It transforms the bike from a 6kW trail machine into a 20–28kW performance beast — without touching the motor, suspension or frame.
In this guide we cover the best 72V ebike batteries for the LBX, what controller you need, real-world power figures, and which pack offers the best value for UK buyers.
Why Upgrade to 72V?
The stock Sur-Ron LBX runs a 60V 35Ah battery producing around 6kW peak. A 72V upgrade battery increases voltage by 20%, which — combined with higher-capacity cells — pushes peak power to 20–28kW depending on the pack and controller combination.
The result: faster acceleration, higher top speed (typically 55–65mph with matching controller), and significantly more torque for hill climbing and technical terrain. Range also improves: a 72V 45Ah pack contains roughly 3,276Wh versus the stock 2,100Wh.
What You Need for a 72V Upgrade
Important: a 72V battery alone will not work with the stock LBX controller. The OEM controller is rated for 60V maximum. Running 72V through it will damage or destroy the controller. You need both a 72V battery and a compatible aftermarket controller (eWatt, EBMX, Votol EM-200 or similar).
The 60V upgrade batteries (eWatt 60V 53Ah, Chi Gladiator 60 Max, Chi X60 Compact) work with the stock controller and are a simpler, safer starting point if you don't want to replace the controller.
Best 72V Batteries for the Sur-Ron LBX
eWatt 72V Race Battery v5 (28kW peak): The most popular race-spec option. 72V 45Ah, 3,276Wh. Delivers 28kW peak with a compatible controller. 2-year warranty. Available from VoltTrail.
DHS GT 72V 50Ah (charger included): Best-value 72V option. Comes with a fast charger, ships immediately, and delivers 20kW real-world power on the stock eWatt or Votol controller. Popular with trail and green lane riders who want more range without full race spec.
Chi Battery Gladiator X72 Compact (72V 38Ah): Slim-profile pack that fits without frame modification. 25kW peak. Ideal if you want 72V performance in a compact form factor.
60V Upgrade Batteries (No Controller Needed)
If you want more performance without replacing the controller, the 60V upgrade packs are the simpler route.
The eWatt 60V 53Ah and Chi Gladiator 60 Max (60V 60Ah) both work with the stock LBX controller and deliver 18kW peak — a significant step up from stock. The Chi Gladiator 60 Touring (60V 70Ah) gives maximum range at ~40 miles per charge.
Is a 72V Upgrade Worth It?
For trail and green lane riding: the 60V upgrades deliver excellent value — more range, more power, and no controller hassle. For racing, freestyle or anyone wanting maximum performance from their LBX: yes, 72V is worth it. Budget approximately £1,200–1,800 for a complete 72V battery and controller combination.
