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.

The basic thing is you need a 3s Jst xh balance wires and balance charger like imax b6 charger or any similar ones.

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 ;D Title: Re: 18650 cell 4P3S Battery Pack Post by: prabal276 on March 02, 2016, 04:51:22 PM 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 : (http://i66.tinypic.com/35lhfz8.jpg) P.S- It was just my Silly humor. Do not take it seriously Title: Re: 18650 cell 4P3S Battery Pack Post by: rastsaurabh on March 02, 2016, 04:55:15 PM 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. Title: Re: 18650 cell 4P3S Battery Pack Post by: prabal276 on March 02, 2016, 05:12:16 PM was that laptop batteries?

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. Title: Re: 18650 cell 4P3S Battery Pack Post by: Tanmay.mathur on March 02, 2016, 06:05:47 PM Will weigh 560 + grams.
