Tenergy 31001 18650 Battery Pack
3.7V / 5200mAh / PCB Protection
Tenergy has come out with an all new 18650 battery pack: the 31001. Featuring a power-packed capacity of 5200mAh, the 31001 battery pack is a significant step up from the 31000's 4400mAh. This pack is completely rechargeable due to the li-ion technology within its two 18650 cells. The 31001 has a longer life than traditional NiMH cells, and doesn't suffer from memory effect when charging. Lightweight, energy-dense, PCB-wrapped, and protected with a built-in IC chip and poly switch for (over/dis)charge protection, you'll be hard-pressed to find a better 18650 battery pack than the Tenergy 31001. In fact, Tenergy recommends these for building battery packs, and can be increased to 7.4V/5.2Ah packs when connected in parallel.
