Hi,
So I recently completed my solar upgrade from the standard 140w to a 340W panel and a 100/30mppt victron controller.
I also installed a battery sense module which tells me the volts and temp at the battery so any voltage drop caused by cable loss is negated - this is the biggest issue with controllers is they dont bulk charge the battery to the correct voltage.
The controller is excellent and over bluetooth I get a bunch of config and data.
Now the question
I have the universal AGM's which have very limited specs online. this is only one I can find.
https://www.solar-electric.com/lib/wind-sun/D5751.pdf
this document says a "cycle use control voltage" of 14.6-14.8volts. I am taking this to mean that they want bulk charge to between 14.6 to 14.8volts. which is pretty high
I can configure my new victron with this charging profile. before I do, does anyone have better specs for these universal batteries?
