Hi guys, i was making a robot this week. And suddenly i came to think about the batteries. I was planning to use 2 li ion cells from old nokia cell phones. I happened to read about handling these cells and it says that u have to drain them bfore soldering. It also says that we have to use a balance charger. So heres what i had done so far.
- I took two 3.7v cell phone batteries ( to make 7.4v)
- I drained them using the phone and a couple of bulbs
Now what shud i do? Here r my questions
- How shud i wire the two batteries so that i can charge it again with a balance charger?
- Shud i take the current limiter out?
- Is it safe to solder?
