temperature and voltage keep battery lipo
« on: June 20, 2021, 03:26:00 pm »
1) the temperature in my home ranges from 31-34°C for maximum long term storage is it better to keep Lipo at 3.85V or lower it to 3.6V??

2) If I don't have the smartphone and the original charger To charge discharge a xiaomi BM20 and Nokia BP-5L battery what is the best option?

Hello again.

3.85V is good. 3.6V is even better. I suggest you print this out, frame it and put it on your wall.

For 2), there is no good answer. If you know how, you can design a good charger but that's a lot of work and requires competence. Another option is getting the original smartphone, that's definitely the easiest way to get the proper charger circuit and proper contacts for the battery. Third option is use some Aliexpress crap which may or may not work and may be lethally dangerous to use.

Please, this is your third thread with more or less the same question.
The reason for not getting more answers is that there are no definite
answers to your question, only rough guidelines. And these has been
provided in your other threads.

I will lower the voltage to 3.6V this voltage also works for counterfeit batteries or from a simpler manufacturer? does all Li-Po have a lower self-discharge rate at 3.6V?


the resistor just touches the contacts of the BM20 and BP-5L batteries and discharges the battery? Universal charger LED takes a long time

I don't know the best option to charge because I don't have the smartphone and the options are few to charge the Lipo BM20 and BP-5L so I asked for suggestions

Fourth actually fifth, I reported one, which was removed (so maybe more).
