Well done bro.
Thank you 😊
بسیار عالی 👍
Nice
Good Good Gooodd..
Too Good
Thank you 😊
Just curious is it work if we charged it via old type 9v battery charger like Energizer compact charger, Not through usb port?
No it won't work, also will damage the battery and converter module..
very tidy
Backup how many hours tell me
Backup depends on your Application i use it for RC car remote which gives me approximately 9 hours of backup. Which is a week useage..
did all lipo battrey have low voktage protection already ??
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??
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?
There is a TP4056 module available with stepup voltage feature but the one i used doesn't have it... Thanks 😀
@@TechRallyofficial I see, thanks :)
@@TechRallyofficial Do you think the charging board can charge 2 batteries in parallel?
Yes, but you need to use same capacity and same model battery..
I would set the voltage all the way up 😂
😂
a dab of hot glue over the pot on the boost board will help keep it set at the right voltage even with vibrations...
Good idea 💡 ,
Thanks for watching 😊
easier to buy one
Everything is easy to buy,
But nothing can give the satisfaction doing yourself..
Thanks for watching 😊
