Hi, my color control is incorrectly showing batteries at 100% when they are only at 13.7V. I have another monitor which correctly shows the real %age charge at around 89%. Any ideas?

Color control/BMV 700 showing incorrect battery charge %age
Hi Zed. I know the figures on the GX can 'flick about' a bit as it samples, but drawing 11W and holding V in Float means they're 100%. Your batts aren't pocket sized (from memory), so up to you which meter you trust.
Fine to trust V or A on a meter, but SOC needs user input to calibrate. Any brand. And if that other one can't be tweaked, it's landfill. Perhaps it's just converting V directly to SOC? - definite landfill..
Tanks John, I hear you on that, except I know that they In a few days they will get up to 14.7v. They are a bank of 4x120ah ages by the way. So are you saying that they actually are 100% charged even though they are at 13.7v and won't be any more charged in a few days by which time they will show 14.7v?
