Turnigy Bolt LiPos are built to the highest standards and are capable of providing competition level performance. A new chemistry composition matrix allows them to be safely charged to 4.35 volts DC, which is higher than the typical nominal voltage of 4.20 volts DC inherent to LiPo battery packs (requires Turnigy Neutron charger). All Bolt high performance battery packs include gold plated balance leads and silver plated, heavy duty discharge wires. These battery packs are particularly ideal for use in high current draw applications such as 3D helicopters, EDF and F3A. Available in all HobbyKing warehouses.
