li fe po4 battery upgrade?
I am considering upgrading to lithium batteries has anyone here don that. I am looking at installing 3 100Ah batteries in parallel and using a PD 9160 converter to recharge them when my Outback solar...

I guess I fail to understand why that, intrinsically, multiple Li standalone, drop-in type Lithium based batteries (i.e. batteries with built-in charge management circuitry) can't be ganged together - in a BALANCED configuration - just like lead acid batteries can be and should be.
It seems like the Li battery's built-in charge management circuirty should not care about, or know about, other batteries around it if they are all seeing identical external loads, as they do if hooked up in a balanced way. "Hooking up in a balanced way" is merely a matter of maintaining - among all the batteries - equal current path resistance (i.e. equal cable lengths) to the loads whenever multiple batteries of the same voltage are interconnected in a parallel configuration. This assumes that all of the drop-in type Li batteries in a multiple battery bank are the same age of the same model from the same manufacturer.
