I've seen several articles and videos on batteries for ebikes and power walls.
The techniques are similar but some of the details vary.
Spot welding battery terminals to nickel strips seems to be the best way to connect to the cells without damaging them with soldering iron heat. On the other hand, I'm not sure how much I like that nickel strip as a conductor.
BMS sounds like a good idea but it also seems like some BMS may cause more problems than they solve.
Who here has worked out the trade-offs in battery construction and figured out the best construction methods for a DIY pack?
Lastly, I'm getting a case of new old stock batteries. What is the best method for testing and balancing them before I assemble them in to a pack? I don't want to spend a fortune on a charger/tester but I also don't want to spend a month testing batteries.
