We charged at the same 120 amps DC at 12v nominal with the AGMS for the whole time, except when we were at 180 amps the early days. We could only control field % then so got automatic reduction at...

Your charge rate is actually pretty close to what we have only we would have higher DC amps and lower voltage on the DC side as you do. We charge at a bit over 120 amps at 13.7v and by the time you...

Just like our monitor does.


A couple of issues we ran across when trying to set an 85% SOC synchronization point was the limitation of the tail current, which can't be set higher than 10% of...

Thanks Avanti, great information.

It does give some insight as to some things I was wondering about.

IMO, cumulative AHs drawn is big one for overall life considerations, especially when...

I think you are correct on this, and it was my first impression when I read how detailed their warranty was stated as cycles, miles, and time. I wonder if they are also tied into the vehicle history...

I was thinking the shunt might be in the Cerbo or standalone, but in the same place as the control makes sense. I tend to think, probably, based on the smaller system setups that all the current...

I assume the BMS does not have all the current going through it and controls external relays?


I also assume it probably has access to a shunt somewhere in the system.

Very interesting indeed, and especially to me the holding at 100% full all the time as that has been more and more being defined as not a good idea. Maybe Victron knows it is not as big a deal as...

Do those monitoring keep a charge cycle by cycle history of depth, or even better a continuous SOC graph which would be slick if it was easy to have it sort out things like DOD range total or such.

Thanks Boxster, great data point.



I hope they got it all straightened out this time.


I would imagine that the high end Victron integrated systems would be similar, although they...

How are Volta units doing over time?

Lithium systems are proliferating very quickly and products are, hopefully, maturing with the longer real world feedback that is out there by now. Recommendations are still all over the map for how...
