This is a Graphene V3 high voltage ULCG 4000 mAh 7.6V 2S shorty battery by Maclan Racing. The Maclan Racing "Race Formula Graphene V3" battery is the latest 2020 chemistry. Maclan continuously evolves the batteries with the latest technology to improve capacity/weight ratio (for better physical spec) along with lower IR (for better discharge performance). These properties will provide more competitive performance for extreme racers.
We also created all new ULCG (Ultra Low Center Gravity) super slim case options for both stick and shorty styles. Those will provide more competitive performance for extreme racers. The Graphene V3 offers all the popular configurations, (stick and shorty) for both on and off road applications.
The MCL6019 improves its capacity from 3600 to 4000 mAh with the same super slim 18.5mm package and same weight.
