got an incredible deal on battery packs, brand new in the box from a exoskeleton robotics company that went out of business end of 2023. Got these packs for $100 a piece local pickup (www.batteryhookup.com). The batteries packs were manufactured in Sept of 2023. They are a 14S5P config and contain Molicel 42a's in them. It had some proprietary BMS built in and a 100 amp rated fuse. I know these cells in this 5p config can easily do 200 amps. The pack build itself will fit well in my application, so I do not have to completely break this pack down. I have one stripped out already, tested the batteries in series, then hooked them to a temp BMS to charge and balance the cells. When I go to use it, I want to add on a BMS that is capable of more amps. Maybe 150a or 200a and put those Molicel's to use. What do I need to look out for in the pack build that might not support the extra amps? For one, they use these tiny bare wire pairs from the buss bar to the batteries. Look a little flimsy imo. Also, I planned on using the original positive and negative bolt on terminals that I left intact, but my spidey senses tells me that might be problematic down the road as well. I am no expert in the higher voltage/amp arena. So I don't know the acceptable gauges are on this level across key areas in the whole pack.
Have new battery packs that I am stripping the proprietary BMS and adding one that is capable of more amps. What do I need to look out for?
