I know there are a lot of threads about this topic already, but I still have some questions about it. Anyways, I am thinking about making a 50-80 thousand mAh power bank depending on the batteries and how many of them I get to build them up. I will need a protection board if my batteries do not have built in protection. Then I would also need a charging board. If I do not have a protection board or built in protection, then the power bank could catch on fire, a safety hazard. I obviously don't want this power bank to be a safety hazard. So I am just wondering if this will work. So I am thinking I could use this board to charge the batteries:
However, I don't know if it can handle the current. If it can't, where is a link that would have all the nice features that this board has like led indications with at least 1 usb for my phone/devices?
I know the batteries here seem legit and has built in protection, so wouldn't need a protection board:
With these batteries, I would probably buy like 16 of them, so 16x3400 mAh=54400 mah and wire these in parallel. So these batteries I am like 90% sure they're not fake.
Anyways, thanks in advance.
