LingsFire 2pcs 18350 3.7V 1500mAh Rechargeable Li-ion Battery

In short, 1500mAh batteries in pair lasts for good few hours - thought there is a voltage drop when it nears complete discharge.

Comes well packed, 2 batteries in the box - both sides almost looks same but finding out which is positive and negative is not that hard. Important rule is to keep recharging before it completely drained out. That will keep battery healthy and you won’t notice the voltage drop

They are non-protected batteries, but overall I’m happy with the purchase. These batteries are advertised as 1500mAh but please expect only 10-15% lower output as most of the other batteries do. Please do check out the pictures to see how the both end looks.
