Have you run into a situation where the charge mos is off but the app is showing the cell temp higher than 32 degrees (40 degrees)? Can't get a charge into my battery right now as a result.
Thank you for making the video! I'm new to all of this so I may be missing something, but why not just use an absorption of 14.2 or so, which would be enough to trigger the 100% reset, low enough that the charger would actually get to that voltage (so it doesn't get stuck at absorb forever), but not so high as to trigger the over-voltage charge shutdown? Then you avoid the drift and need to manually reset like this. I'm about to upgrade my house from AGMs to a single Epoch Dual Use 300ah battery -- and the manual recommends 14.2. I will have some Victron charging equipment (DC to DC off engine battery/alternator and MPPT 100/30 solar, plus a Kisae inverter/charger for shore power), but I don't plan to use Victron communications, and I only have the single battery so I don't have to worry about multiple batteries getting out of sync.
Your planned battery doesn’t have this full charge protection warning/charge disconnect. The parameters are mentioned at about 6 mins. Edit: I amend my statement to “I don’t think your planned battery has this…” (if @mvintrigue isn’t sure, neither am I! 😉)
As Jim Duke mentioned the full charge protection parameters are greater than 14.0 volts, less than 3.6 amps, for more than 10 seconds. You can charge to 14.2 but you will enter into full charge protection. Again if you have a single battery not an issue but with multiple batteries you would need to clear the FCP. I dont believe the Essentials or the Dual purpose have full charge protection
@@mvintrigue-trawlerdiy1101The 300AH Essentials will open the charge FET at 14.70 battery voltage or 3.70 cell voltage. The SOC counter will reset at 14.20 so there is need charge to the protection level. Also, the 300AH Essentials calculate SOC strictly on AHs withdrawn and like the 460AH its not very accurate.

If the temp dips low enough to shut off the charge mosfet (32) it has to rise above 41f for a bit before the charge mosfet will turn on again.
@@mvintrigue-trawlerdiy1101 Thanks. It's charging now but not sure why the heaters never came on.

Good info - thanks !
