Hi Guys
I have only been in this hobby just under a year but 'm learning by my mistakes, fast :-) Question, Something that is bugging me 

1. I have a balanced charging board but I'm a little worry about charging more than one battery at a time could somebody please confirm i have understood this correctly.
I have 2 x 350mah 3S lipos 

The instructions say 

I = charge Current 
V = Charge Voltage  
n = battery Quantity

I=i+i-i+in (n<6)                                                   I think this should be 700mah


V=v1+v2=v3=vn (n<6)                                         Not too sure what to put here (set charger to 6S? surely not!!)   I think this should be set to 2s on my charger as i have options for charging 2 to 6s at the correct voltages preset.

Thanks for reading, I'm just trying to avoid a lipo explosion.

Cheers 
Col

I think Oscar as everything you need covered!
Here is the link: https://oscarliang.com/parallel-charging-multiple-lipo/

Set to 3S because you have 3S.

Select lipo battery type and voltage should be automatic. Otherwise 4.2 x 3 cells = 12.6v

Current should be 0.7 amp

Read the tutorial first.

Thanks For the information guys
