Simple question I think?
On the BMV-712, If the auxilary input, used for the Starter Battery, is at 12V, will the BMV still work and keep all the current data if the main power input is removed? So when the Main input is back, it will carry on where it left off in terms of data?
Unfortunately I didn't think to check this before I started a couple of battery discharge tests, and which I am now in the middle of so cannot check this with either of my BMV-712s in case the answer is no and I loose the SOC and Ahs used info when power is re-established.
(I am doing a full discharge test on a LiFePO4 until the BMS cuts out so expect to have the 12V cut out at some time)
