2 LiPo Charger & Boost Converter? TP5410 Test Andrew: GreatScott, the over discharge protection of the tp4056 kicks in at 2. 5 volts. I have constantly read that 3 volts is the absolute minimum voltage that a lipo battery should be at before damage occurs. Is there something I am missing because every protection board I have come across has the same 2. 5 volt cut off. Is this safe/a good idea? I do know that under a load a battery has a lower voltage and when the load is removed the battery gains back some voltage. I still wonder wether that cut off is too low.

That lipo requires 4. 3v, the circuit looks designed for lithium ion?
Also, you can buy battery packs 1000mah on Amazon 4 pack for under 10gbp and they have protection for short, reverse and under over voltage. So this board with those batteries should be pretty good?

Hi
I am pretty sure you can translate any chinese datasheet using google translate. There is an option to upload a pdf file and translate the whole document. It does a pretty decent job, so dont let the chinese datasheets discourage you!

It looks like your lipo allready has an integrated protection circuit (the tiny circuit under the brown foil at the top of your lipo 0: 32min, so you wouldn't need any protection for the charger, right?

Can you design a circuit for 3. 7 v to 5v 2 amps.
S basically I want to power gsm sim800c and arduino nano together via li ion battery. Along with that I want to charge li ion battery also.
Thanks.

Can you suggest me module work like inverter circuit with lion cells which mean at same time I power device. If mains supply supply is off the device start working using lion battery
reply

is it possible to use this board to charge two of those batteries in series? the total voltage would be around 7, within the range of the 10 volts? and would it be converted to 5?
reply

Late, but in this case, would the original idea of using the TP4056 protection circuit combined the boost converter be the safer and more reliable choice?
reply

Aww, sad. I though you found a perfect replacement to the pair. Oh well, it could still be usefull for some applications. Or go adafruit.

There are super small boards for power banks, they give up to 900mA at 5v (rates 1A) charge your battery and have discharge protection
