Luna Cycle 72V Sur-Ron Battery Pack

The Luna Cycle 72V/40Ah battery pack is the gold-standard range extension upgrade for Sur-Ron Light Bee X owners who need more miles between charges. Built with premium Samsung 40T 21700 cells in a 20S4P configuration, this pack delivers 2,880Wh of total energy, a 50% increase over the stock 60V/32Ah battery.

Designed as a direct drop-in replacement, the Luna pack uses the same form factor and mounting points as the factory battery. No frame modifications, no adapter plates, no rewiring. Remove the stock pack, slide the Luna pack in, connect two plugs, and ride. The entire swap takes under 5 minutes.

The higher 72V nominal voltage also increases top speed to approximately 52 mph when paired with the stock controller, or 60+ mph with an aftermarket controller like the EBMX X-9000. Range extends to 50+ miles of mixed-terrain riding thanks to the higher energy density Samsung cells.

Built-in BMS (Battery Management System) provides cell-level balancing, overcurrent protection, thermal monitoring, and short-circuit protection. The pack is rated for 800+ charge cycles before reaching 80% capacity. Includes a matched 72V/5A fast charger that delivers a full charge in approximately 8 hours.
