Is the lifepo and lead acid together in a series? if so that lead acid is probably holding the other back.. They have very different charging curves. I think good Lifepo4 can easily last 10 years. But mixing chemistries isnt great for them.
No I have the Lifepo4 as one circuit and the lead acid as a completely separate circuit.
They both have 2 of the 4 300 watt PVs powering them.
So they are standalone systems. Yes Lifepo4 and lead acid would not mix well in one circuit.
The lead acid circuit powers a large 5000w inverter I use for power tools and backup in case the Lifepo4 circuit ever fails while the Lifepo4 circuit/battery powers 3000watt inverter which feeds the fridge and lights and laptop etc.
This is because Im not as sure off the Lifepo4 handling heavy current loads as the lead acid...but the Lifepo4 is better with constant moderate loads and holding charge over night.

Oh cool. That makes more sense. So are you offgrid completely?
reply
Yes.

Some lifepo4 can start cars now. I do know they arent as good at large motor current draws though
reply
Yes the 110 ah lifepo4 is spose to be ok up to 100amp draw but the skilsaw motor probably draws a bit more than that when its starting up and working hard so safer to use the lead acid battery for that.

In my experience most of these. Batteries will push more amps than they are rated for, no problem.
