The 7.4v Li-ion battery pack is the same as the 2 LED's 'Epic' version - with it's 4 cells giving 5200mAh. The battery has built in charge, discharge and short circuit protection. In tests the 7.4v Li-ion battery will last up to 35hrs on low and 2h 15min on max (The burn times have been tested in optimum ambient conditions and may vary from those times shown). The PVC case is small enough to fit under most stems, top tube junctions or slip into a hydration pack or jersey pocket.

The double IION - the latest development in SIGMA rechargeable batteries is called the IION XL. It is, as its name suggests, the larger version of IION. Its 4 Li-Ion cells provide optimum energy for the POWERLED EVO and almost double the burn time of the KARMA EVO.
Small, light with plenty of Li-Ion power. It benefits in particular from its low weight (140 g), its high energy ratio and its resistance to extreme temperatures. Its low self-discharge makes the IION much more efficient than NiMH or lead rechargeable batteries.
