Bottom Line: This cell has a low current rating, 5.2A, but uses the safer “hybrid” NMC (nickel-manganese-cobalt) chemistry version of “ICR”. It does not use the more volatile LCO (lithium-cobalt oxide) chemistry version of ICR that is also used in LiPo’s. NMC chemistry is used in the 25R, VTC4/5, HE2/4, and other cells we use often and consider to be pretty safe.
It also has a low capacity rating, 2600mAh, compared to several other <10A batteries. There’s very little reason for a vaper to use this battery. If you do use them, stay below 15W to get what you can from these cells without the weak battery warning appearing immediately. The 18650 ratings table has been updated to include this cell.
