MPPT 100/20 and Bioenno Battery with Built-In BMS

Hello,


I have a MPPT 100/20 charger with a Bioenno 30Ah battery that has its own BMS built-in.

I'm wondering if I need to change any settings in the MPPT due to the embedded BMS in the battery. As I look at the MPPT's history data on its Bulk/Absorption/Float states they seem reasonable for the setup I have, but I wonder if the MPPT is really achieving any of those states given the downstream BMS in the battery, which the MPPT is unware of. Maybe the charge mode of the battery is being dictated by its own BMS and I'm never really officially in Bulk, Absorption or Float.

As long as you have the MPPT charger voltage settings set according to the Bioenno battery recommended specifications everything will work just fine.
