Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

No temp compensation I'm aware of. My AGMs showed a full charge usually around noon.
When I set the Absorb voltage on the Outback, that tells the controller to start charging at Bulk (whatever voltage it chooses) until the battery voltage reaches the Absorb point. That's what it does, that's what the manual says it does, but that's not what I want. I want the voltage to rise to the 58.4, then taper off to Absorb.
The only way I can see to workaround this is to set the Absorb to 58.4 and the Float to 55.2 (the absorb voltage.)

i think he said the lithium needs 58v for a fast charge
