    Hi, i have a small power bank which consists of 3 18650 batteries in series which are soldered together. Because these batteries are soldered together i am unable to simply buy a charger for these batteries and recharge them. So my question is how can i safely recharge these batteries without overcharging? At what voltage should i charge them? And how to prevent overcharging? Thanks for any help
