6.5 kWh high-voltage lithium battery pack for Stark VARG MX 1.0 Gen 1 and Gen 2. Delivers the full performance spec of the original build with a max operating voltage of 420 V. This is the factory replacement for first-generation VARG MX bikes only — not compatible with VARG MX 1.2, EX, or SM. Plug-and-play installation with no software changes required. The batteries must be handled carefully and always stored and moved in their shipping crate when not installed on a bike. Keep away from humidity, heat and fire. Aftermarket skid plates that are not approved by Stark Future can damage the batteries.
