Under voltage setting of 2.6v,
I think the inverter will hit under voltage before that.
I ordered mine on Jan 14th, 2021, no updates on Fedex.
Alix says they have till April 24th to get here, what the LFE!
I think you're right, I did my discharging with a victron 12|250 inverter and I forget what I set the low voltage shutoff to. I did not have a low voltage alarm on the smart BMS, but I had let my phone's screen lock and figured maybe it reconnected and had cleared ?
I didn't know the smart BMS units (overkill solar type) would adjust battery capacity without hitting the programmed low voltage disconnect, but it did (the 98.82ah figure)
I charged it back up with a Victron MPPT and 24v power supply as PV, to see how wonky things would get in normal charging conditions without the aid of a RC hobby balance charger. The MPPT with aid of a Victron Smart BatterySense nailed 13.8v on the nose as measured by BMS and Victron app. This is better behavior than I get in my other setup with a BMV712 providing voltage and temp.
At a 20 amp charge rate I was obviously exceeding the balance ability of the BMS by an enormous factor, but at the end I was at 13.8v and a high cell of 3.472v, ~30mV delta. Once a brief absorption ended (to give additional balance time, but ended up not having any benefit), the cells instantly settled to 1mV difference. I could run this as is but I decided to parallel the cells and take them to 3.6v. I just completed this using the iCharger X6 once again at 30 amps, worked great and didn't overshoot.
I'll let them hang out in parallel for a couple hours and then reassemble in series for another discharge test, then another charge through the MPPT to see if that 30mV high/low cell difference is gone at the same charge rate. I don't know if that's to be expected, this is my first time doing a proper top balance.
Just watched Will's video on the overkill solar bms and damn do I have cell envy. Would almost be worth getting in to 3d printing to try and make the cell caps that the Fortune cells have. Minimal bulk added, compression and mounting options all in one, terminal protection, a shelf for BMS or breaker. Would be so damn nice.
