What's wrong with my battery capacity indicator?



i use this battery capacity indicator

i’ve a 12s setup 44.44v (2 batteries 6s 8000mah 35c 22.22v each one), they are almost full 99%
battery 1 - 4.19, 4.20, 4.20, 4.19, 4.20, 4.19
battery 2 - 4.19, 4.19, 4.19, 4.20, 4.20, 4.20

i use this power switch

this is a picture of my build, i only want to show the capacity indicator when i turn on the switch

but the battery capacity indicator only indicates 84%, why? any idea?

thank you


It might be on the wrong mode. There is a button on the back. Hold this down as you power the board on and you should be able to change the mode.


Also, your power switch might melt given it handles such low current.


Yeah, wiring looks great. Definitely some configuration issues


thank you for all your responses! :slight_smile:

@lox897 yesss!!! it works! when i turn on with the button indicator pressed i can choose an option from 0c to 15c, then to save the setting turn off and turn on again.


Awesome. Set it according to what 12s is.


Personally, I think it’s better to monitor voltage.
It doesn’t seem like percentage meters are accurate enough.
Also, you need a high voltage anti spark switch.
The switch you have won’t hold up.


Any recommendation of volt meter?


I think the meter you have can switch to volts.
