A high performance HV (11.55v) Li-Po pack with a handy built-in capacity checker for those that want that bit more performance from a Li-Po pack, but within a compact size and weight.
Unusually, there is also a small electronic capacity checker built in. No more guessing if the pack is charged or not, just press the button to check!
To use this performance fully, you will need a battery charger with an HV charge regime. The latest Sigma chargers like the EVO, ECO II, Touch II etc all have this.
