Btw… on the discharge floor setting, why 50% ? As it is Lithium why not 20%?

Thanks Vic I have made the changes. Will wait to do the sync until I get a few solid days of sun to get batteries topped off with the camper main pull plug off.

Small addendum  ...since you have BB batteries, if you have heated BBs the slight current they draw does not go through the shunt; hence, the SOC will not reflect the amount of current the BB heaters in your batteries have used..

 

I like the heated function on my BB since I can leave the Hawk in the sun while skiing during cold temps [below freezing] and the BB will continue to receive the solar charge...without the heater the BMS will stop charging near 32* F.

Thanks on that thought. No they are the non heated so won't have that ​current draw. I did move my DC/DC charger out of the battery box and mounted on the vertical beneath the seat (in front of the turnbuckle door. With door opened and I have a black fly screen,  the charger gets lots air flow. I need to review more about the charger as I have a feeling the wire that goes from the Truck to the camper is not that heavy a gauge. Would mean a lot of work to get a new cable in ...not sure it is worth the effort. The charger wire screws aren't that big to accept wire much bigger. I need to review the settings to be sure they are ok. (I have a smart alternator).

Seems my truck dash battery charge indicator states 15 Volts at times. seems high but what do I know?!

Very much appreciate everyone on this thread! 

 

Had the same question. And did not understand why the red to shunt was on one battery and black to shunt was on the other - that was a great explanation!

 

I've been lurking for awhile. Got my Victron BMS - and tracked our usage for a season (as someone suggested). Just installed the MPPT 100/30 - though that might be overkill for our use. Finishing off the wiring. Now I'm wondering if I shouldn't have got a bus bar - but the room is so limited in the battery box of the fleet. 

 

Mainly here to say a big thank you - I would not have got this far without people here!

If there is little room for a bus bar, you might consider a PowerPost Plus to meet the need.

I have found them useful for tight spots.
