Renogy Settings for Victron SmartSolar MPPT 100/30

Victron Energy SmartSolar MPPT 100 Parameters.pdfRenogy Battery Charging Settings.pdfI have a Victron SmartSolar MPPT 100/30 solar charge controller and two Renogy 10 Ah Smart LiFeP04 Batteries. I reached out to Renogy to ask what the proper charging parameter settings were for their batteries. They responded with the following chart. The parameter descriptions don't exactly match the Victron setting descriptions. I assume that Renogy's "Boost Voltage" is the same as Victron's "Absorption"

Looks like you're correct about boost. Boost return is float. And set absorption as low/short as possible. They say none.

@phk1853@gmail.com @kevgermany Boost return is float

Looks like Boost Return is the equivalent of victron's "Re-bulk voltage offset"

Allowing the Li battery to go down to 13.2v would equal about 60-70% Soc?
