From Vampire Racing:
Vampire Racing’s new LiPo safety bag is ideal to charge, discharge and store LiPo battery packs in. Made from fire-resistant fabric the bag measures 185x70x60mm which is large enough for at least two or three standard 2S LiPos or one 4S pack. Flashy Vampire Racing graphics make the bag stand out while protecting the pit area and surrounding people in the unlikely event of a LiPo pack going boom during charging, discharging or storing.
