Hi @ephan -
Those ratings are not relevant! The power the BlueBoat draws does not flow through the BMS. The BMS is connected in parallel to the cell voltages, and so 5A of equalization current is ample - typically this only is 100mA.
This is the unit I’d recommend!
Hi Tony, I have another question for you. I’ve setup the solar panel with the Victron MPPT and blueboat battery, but the victron will only start charging when the PV voltage is at least 5V higher than the battery voltage. With the batteries running up to 16.8V, it’s having trouble reaching the cutoff of 21.8V to start charging without strong sun conditions. Once it starts charging it’s fine, PV voltage can be as little as 1V higher than battery voltage, but it’s just struggling to start sometimes. Did you use a workaround for this?
Hi @ephan
That’s correct, the panel voltage does need to be higher than the battery- although I would have guessed the difference could be smaller than what you’re finding. The panel I used had a sufficiently high open circuit voltage so that when doing
MPPT tracking, the battery charged just fine. I think the workaround is the battery voltage dropping, as it’s not likely to remain pegged at 16.8 for long!
