Hi I am going to built a 280ah 12v 4 cell lifepo4 battery for the first time, this will be to replace the current lead acic battery bank in place.
Well while reading / researching before the built I came across this in a sticky here on the forums from @Will Prowse :

[/QUOTE]12V 4S LiFePO4 Battery w/ BMS:
- Absorption: 14.5V
- Float: 13.6V
- Inverter Cut-off: 10.7V-12V (depending on size of load and voltage drop etc
But when I look at the spec sheet for my 1500w pure sine inverter it lists the low voltage cut off as 10.2v
The inverter is mainly used to run the microwave which runs for 3.5 minutes twice a day and when running my draw at the shunt is around 120amps.
As far as I know the low cut of voltage on the inverter is not adjustable, so will this be an issue even before I start to built the lifepo4,
Actually after typing this all out I just realised about the daily bms cell low voltage protect setting, I was gonna set it at 3v, so am I right in thinking this will shut the battery of once it reaches 12v assuming all cells are equal.?
