Parallel charging batteries

Luckily I only have 2 batteries

But handy tips if I get more.

2 batteries equals about 10-15 minutes of flighttime, you will want more once you go out flying.

I've got 5 3S batteries for my Eachine and 4 new 4S ones for my 180 quad. Till now I've been charging single batteries, even though I did buy a parallel charging board a while ago. I haven't used it yet because I'm not exactly sure what settings to use on the charger. Seriously don't feel like starting a chemical fire in my livingroom, must be careful.

But I didn't buy that parallel charging board for nothing, so I am going to try to see if I can get it working.
Over half a day for charging 5 batteries individualy is much too long anyway, and having to switch all the time gets annoying after a while.

 

Watched several videos and gave it a try, after a bit of carefully messing around I got it working. I can now parallel charge my batteries.

First had to discharge 2 batteries to equal the others. When I finally started charging I found it went very slow, so I slowly raised the amps step by step, while checking the batteries for heat. All remained cold so I assumed it was good, and waited till they finished charging. Once done I checked and saw they where all charged exactly the same voltage.

Very happy with this. Not only it saves time and trouble, it's also nice I don't have this 'fire alarm' going off in my house 5 times a day.
The batterycharger has a rather loud 'finished charging' alarm sound that sounds exactly like a fire alarm.
