........ I have the dipswitches set on my charge controller but have not hooked it up to my computer yet as i do not know what values to enter for things like absorption, float, and what not. If any of you can provide some insight, that would be appreciated.

Tell us about the specs of those batteries, any numbers you can share?
Chemistry - LFP or NMC?
number of cells in series? ( that will enable you to go from cell voltage to pack voltage settings. Probably something like 12 or 14 for a 48 v pack )

I have the 45amp tristar mppt controller and two of the 48v powerwalls from bigbattery.com (https://bigbattery.com/product/48v-li-ion-powerwall/). These powerwalls each have one anderson sb50 port so i was going to make two y connectors, one to parallel them and another to go from the batteries that are connected to the inverter i have and the charge controller (similar to this but with 6 awg wires https://www.techdirectclub.com/ander...llel-cable-36/). I have the dipswitches set on my charge controller but have not hooked it up to my computer yet as i do not know what values to enter for things like absorption, float, and what not. If any of you can provide some insight, that would be appreciated.

Thanks
