MB Specs - 8A per channel? variable voltage per channel? - gregoryx - 04-07-2025
Looking to use an MB board (KinCony ESP32 Battery Monitor) to monitor DC circuit power.
I can't tell from the specification if it's 8A per channel or 8A for all 16 channels?
And it's unclear if it can be different voltage on every channel? Can I have 12VDC on one channel and 24VDC on another channel and have correct measurements on both?
thank you.

1. can you take a photo of your MB PCB. i don't know whether you have bought 8A version? because it according to "collecting resistors".
2. if is 8A version, that means per channel for 8A.
3. sure, different channel can detect with different voltage. for example, channel1 detect DC12v. channel 2 detect DC24v.

I haven't purchased it. Hence the questions! :-)
So if I purchase one today it's 8A per channel and variable voltage per channel?

Yes

Thank you. Was about to purchase and noticed there's a 16A version. Same specs apply? anything lost by going with the 16A per channel versus 8A per channel? Thx!

if your load current <8A, chose 8A version is better.
if your load current >8A and <16A, chose 16A version is better.

Sorry to pester... is the difference the accuracy? More accurate at 8A than 16A? Any way to clarify the change in accuracy?
thank you.
RE: MB Specs - 8A per channel? variable voltage per channel? - admin - 04-11-2025
accurate according to your load active current. so chose range near by your active current value. Do you think use 1 meter ruler to measure 1cm is high accurate?

Understood. Might have one load outside the 8A range, so... went 8A for accuracy. Ordered. Thank you.
