EVFREAKS Race 81V 50Ah Battery for Sur-Ron Light Bee

Built for extreme performance, the EVFREAKS 81V 50Ah Race Battery delivers up to 60kW peak and 25kW continuous output – giving you all the torque and acceleration needed for serious off-road riding and competition-level racing. With a 550A peak discharge, this battery is engineered for riders who demand maximum power and responsiveness from their setup.

Every unit is hand-built in Germany using Grade AA+ 21700 cells, copper-welded (no nickel), and assembled with premium materials to ensure safe, reliable, and consistent power delivery under the most demanding conditions. Housed in a 1.5mm stainless steel IP65-rated case, and equipped with an active 650A BMS, AWG6 silicone cabling, and QS8 anti-spark connectors, this pack is designed for riders who don’t compromise.
