Li-Ion is good too, as long as it isn't some random cheap brand from China. Panasonic, LG, CATL, BYD, EVE, Samsung, BAK are good names.
I built a 13S10P battery out of BAK 21700 5Ah Li-Ion batteries, I've pulled a 30A load on the battery, and it never got the tiniest bit warm. The warmest I've seen the temps on the battery when it was charging at 20A was 35C after about 2 hours of charging.
My DeWalt tools use the Samsung 50S 21700's, these have a maximum 50A draw. I got bored one night and used my drill with an old t-shirt in a sort of helicopter. It overheated the batteries. I disassembled the pack and found that abuse caused about three to go dead, basically open circuit. No smoke whatsoever. The pack was just hot. That was also an expensive mistake, too. The 20V, 10Ah packs from DeWalt are $200.
