Hello!
I Could use some help, guides and/or similar. I want to be able to charge my power tool batteries off grid. I have been searching and all I could find is that people applied balance charging on the tool batteries.
I have a portable power supply made of 3S 18650 cells (expandable to 4s) and I'd like to use it to recharge my power tool batteries. All of my power tools are based on 12V (old 10.8V) LiOn battery packs. I've got a couple of Bosch tools, drill, jigsaw and angle grinder among others. I've got chargers for these as well (AL 1130 and AL 1115). I need only one so i'd gladly sacrifice one of the chargers for the cause.
My question is if it is possible to bypass the mains on this charger and power it with my 15 Ah power pack?!
Thank you in advance.
