I bought one these from BJ hole sale club which it on sale right now for $39.99
I thought great let me see what inside of it well it has the following——>
I am VERY CAREFUL when working with these types of batteries
One time I was welding on some 18650 cells and the positive side of the battery I missed one side of the tab and in between the “+” and “-“ terminal this was NOT a pretty site the battery was leaking after that miss haps it dose not take long at all when you do for the battery real hot
I make batteries pack off and on for my battery operated tools I also have a battery spot welder to weld these cells (18650) cell and just bought the tool for the battery spot welder to do the batteries that are in a pouch because some time the tab that you can solder to break off and part that still there you can not solder to it you weld a new tab to it that you can solder to
One other note it had 3 no name brand caps on the board that has the USB ports and balancing protection board and has two what looks to be Mosfet,s which caps were replaced
3 high flat cells high amp batteries which has a what looks like a balancing protection board
That part of is good so far but here where the problem starts there NO FUSE it in what so ever on the batteries This is a REAL problem not good at all
It has a flashlight which is real nice and 2 USB ports 2 amps each real nice
The first upgrade is that on the high amp output it is going to have a 10 amp in line fuse
If BJ still has any left next week I am going to buy one more of them to have 24 volt pack when I need 24 volts
