SK-72 V1 Battery — 72V 50Ah Samsung 50S | Sur-Ron LBX

SK-72 V1 — 72V 50Ah Performance Battery

Genuine Samsung 50S cells · 250A continuous / 350A peak · Built for performance controllers

The SK-72 is a high-output 72V battery built specifically for riders running performance controllers on the Sur-Ron LBX. Where stock batteries hit their limit — BMS cutouts, voltage sag, restricted current — the SK-72 is engineered to deliver sustained high power without compromise.

Why the SK-72?

Genuine Samsung 50S cells. The 50S is one of the highest-performing 21700 cells available, chosen for its combination of high discharge capability and 50Ah of real usable capacity. No mystery cells, no relabelled budget packs.

250A continuous / 350A peak BMS. Run your controller at full potential. Where stock BMS units cut out around 90A, the SK-72 delivers nearly three times the continuous output — no cutouts at full throttle, no power drops mid-ride.

Full 72V performance. More voltage means more power at the same current, stronger acceleration, and higher top speed on controllers configured for 72V operation.

Specifications

Perfect Match: SK-500 Controller

The SK-72 removes the battery as the limiting factor. Paired with the SK-500 controller you can run line current settings well beyond stock battery limits — with headroom to spare.

Fitment

Designed for the Sur-Ron LBX platform. Please check dimensions against your frame before ordering — the V1 is taller than stock at 18.5" total height.

Delivery

4–6 weeks door to door. Each SK-72 is shipped fully tested with UN 38.3 compliant lithium battery transport.
