Is it OK to solder wires to this battery ?

by NickName, on 07 June 2019

the ideal would be an 18650 battery holder and solder it, it is how best and safer it is

Really 4Ah, when the best bateries have around 3.5Ah?

There are no 18650 Batteries with 4000 mah in the market, so the manufacturer lied at his description. I measured about real 2100 mah and I dont like liars.

Order came quickly, but the capacity was tested to be only 2200mAh Max.. Other users reported this same issue, so I would only recommend this if the price is lower than another 2200mAh battery..
