Fantastic service
Everything as advertised
Zero complaints.
Decided to go the DC to DC chargers for a few reasons
1) Ben Sterling from Sterling UK got back to me within hours, talked me through it and assured me that a 36si @105 amps will run 70amps of chargers without cooking the alt - 70% load is what the target is and, in reality, what the wakespeed...
So, my choices will be:
Wakespeed vs DC - DC charger
My concern with the oft touted DC - DC charger is 2 x 35 amp (Sterling for $350 each) chargers pulling from the starts will still be loading up the alt enough to cook it.
I'll jump in on this thread vs opening a new one.
I am about to try the alt > lifepo4 charging route
I tried it before with a large AGM bank but cooked the alt so gave up on it until now
We are an ex trawler, big slow spinning motor, often doing 6+ hour runs
We never, ever go into marinas so...
Victron battery monitor is showing overall battery SOC is 77.4% and down -200ah from 840ah
Guessing the app/BMS needs a bit of time to recalibrate itself
Been so long since I needed to do anything I've forgotten the quirks found in the early days.
Yep, just went down below and visually checked. Shot everything with laser thermometer and tested voltage on all cells.
All same and all seemed good.
Unplugged BMS harness, blue lights off and reconnected.

Hi, a year or so ago we bought a batch of Eve280 A grade matched and batched cells from one of the recommended suppliers here.
Made 3 X 24v batteries connected as a single 840ah bank
Did it all by the book, top balanced, noalox, etc etc and they have been trouble free appart from Battery A...
Perhaps it's just one of those weird things.
If I open the app on tablet vs phone it doesn't have a record of it but does have a record of the same on a different battery at another time.
Weird.
Hi, just noticed today that I had an overcurrent alert for 3.362v on a bank of 8 x lf280k cells.
Any idea as to what's going on here?
Thanks in advance
