I have made a battery pack with 18650 cells and the configurations is 4P3S
Now not able to under stand how do I charge the pack
there is some charger available in the market but those charger able to charge a single cell at a time !!!
I need to charge full pack at a time and
I have a B3AC balance charger does it work???

You should reopen the pack .and repack by using these steps.
1. Make 3 nos 4p1s packs
2. Connect these in series.
Now you can charge these using b3ac .but it'll take 2year minimum to charge.

Surajit, There are many online video tutorials available which you can refer. The basic thing is you need a 3s Jst xh balance wires and balance charger like imax b6 charger or any similar ones.

@Tanmay.mathur
Was that sarcasm or Based on real calcs.?
Appears real to me

AS the two years are getting over, suddenly the lights go out and you start the charge all over again. LOL.(If the lights go out in the middle of a charging; the B3ac; when switched on again; starts discharging the cell and then again chargin')
Have a Great time

Hey;
shouldn't it be 18650 mah?
If the battery has 18650 cells (I KNOW that it is stated 3s)
You would require something like this to transport it from your home to the rc ground :


P.S- It was just my Silly humor. Do not take it seriously

I have been using these Laptop batteries for long now. Not for flying but for all ground work.

They are good and search on MY Geek show for details.

Charging is super easy at least with Accucell charger.

was that laptop batteries?

Just some lappies use it.
Man that 18650 is a 3400mah . So you will have a 13600mah 12.6 v battery.
And yeah that WilL take 2-5 years depending on power cutoffs.

Will weigh 560 + grams.
