​Our first EV car designed in just 9 months, (VM24 aka Big Sniff) features 96 18Ah Melasta Pouch cells for a total of 404V, monitored with a custom BMS and encased in a in-house built aluminum accumulator casing. We moved to 10" rims powered by a Turntide AF 125 motor and custom 7075 T6 aluminum driven sprocket/carrier.
