OK!

hello, can i parallel 18650 .21v difference?

[@user-ss4xr2xx5d]

Hey, interested, can you try to make parallel tester for 1Ato40A, because used battery pack for repair.

[@yousun2827]

OK! Thanks!

[@madysouma4254]

Hi is that possible to use different capacity like 2900mah and 2000mah to create a battery pack?

[@yousun2827]

Yes!

[@hassangamal6531]

what is the resistors do ?

[@yousun2827]

Limit current to prevent excessive current flow.

[@kmuralikrishna1582]

Seems good but is there is any cell protection...? What you did here is just measured each cell voltage Measured each cell current(amps) The you started to recharge the cells ..im I right.? And finally when you recharging what is supply voltage? and current ?you gave to the cells? since there are more cells to we need to multiple voltage or current??

Charging and balancing batteries.

[@internettv8059]

When you put different type of batteries in parallel, sometimes they don't really charge. How can i resolve this problem

[@yousun2827]

There is a problem with the charging device or the battery is broken. I haven't had this problem.

[@nazmulhassan7008]

Where i get this charger 😔

[@yousun2827]

You can make this yourself.

friend: good afternoon. For you who make these types of videos, because you never put a connection diagram of the elements for us beginners in learning about lithium batteries... I see that you have a lot of knowledge, but for you, not to share. Thanks and sorry.
