Now before we start digging into battery packs, I want to touch on some safety items specific to lithium-ion cells. Lithium cells in battery packs are always connected by spot welded tabs that connect the positive and negative terminals and you need to be careful when cutting them. Now what? It's just for measuring the cell voltage to see if they are salvageable. If you're into RC and have electric vehicles and have experience with LiPo batteries, you can skip this, but if not, it's important to understand that messing with lithium-ion batteries can be hazardous. Let it run until it's fully-charged. 99. The camera battery didn't do so well.

You'll need to completely drain the battery for this to work, so once it reaches zero percent, keep turning it back on until it doesn't even have enough power to boot. Multi-cell packs have an added feature called a battery management system with a balance function that monitors and distributes charge current and voltage across each cell, making sure each gets charged with the same amount of current and voltage. Most of the time, these batteries will be dead, and I mean dead. 4.1 out of 5 stars 22.
