Hi. I just finished making my first 20s 12p battery pack but I'm having a little issue not sure if anyone could help. My ant bms 300amp is reading 70.5V and my multimeter is also reading 70.5V on the main positive and negative of the pack but through my main discharge cable the multimeter is only reading 61.4. It's very weird to me I have no idea why, if anybody could help that would be awesome thanks.
 
Is this while under load (if so, how much current?), or just sitting there turned on?
