did all lipo battrey have low voktage protection already ??

@TechRallyofficial 2 жыл бұрын

If you use the BMS it will have the over discharge protection

@@TechRallyofficial wait the step up and charge module already have auto stop charging right?? and lipo already build up with cut off low voltage??

@TechRallyofficial 2 жыл бұрын

TP4056 module has auto stop charging (technically its over charge protection) but the battery should not be left in charge for longer time it will cause swelling or damaged. Most of the 3.7v lipo battery comes with over discharge protection if your battery has a small PCB than it has.

TP4056 already has a step voltage feature, why do you use the DC to DC converter?

@TechRallyofficial 2 жыл бұрын

There is a TP4056 module available with stepup voltage feature but the one i used doesn't have it... Thanks 😀

Yes, but you need to use same capacity and same model battery..

a dab of hot glue over the pot on the boost board will help keep it set at the right voltage even with vibrations...
