Battery Ah size recommendations

[pdid]

Good find. I totally bypassed the CBE stuff and just use the DS300 as a fuse box (for now) and don’t get any flashing lights on the panel. I’ve not even noticed if the EHU light comes on or not. Possibly because I now don’t use EHU with lifepo4 and solar! The battery indicators are useless and (on my poverty 100 panel!) there is nothing else of use other than the basic on/off switches. In the future I will remove it and fit some CBE switches and USB chargers instead. If I want to know what’s going on with the power I use the Victron app. I guess if one has a dual voltage fridge or a better panel it is useful to connect the signal.

This was what I suggested in my post?

Lithium leisure battery upgrade

Page 8: Instructions My BB1230 is the green stripe model with one lithium setting.... Reading between the lines I can fit the temperature sensor but it would not be adjustable so set at 0c for lithium. The manual you linked suggests a maximum of +2c anyway which isn't really high enough...

I highly doubt it's doing anything other than lighting the indicator, I suspect you have separate issues with your starter battery so keep an eye on that.

This is just it, the information I have, albeit based on reading forums, suggests the trickle charge for the starter only works whilst this hook up symbol is lit.

From my own experience of the battery alert flashing I believe this could be the case.

The solution in post 680998 would have worked but was far more technically involved, soldering a PCB vs connecting a few wires, so wasn't the solution I was after. It also took me a while to get my head around what I was trying to achieve.....

Anyway, happy for now and I will keep an eye on the starter battery. I have now purchased a multi meter, just need to learn how to use it!

Thanks

Yep, good point, you get the trickle when on EHU. I fitted an Ablemail instead as that essentially works from the leisure battery so also works from solar or will also sacrifice LB charge to maintain the SB if you have no charge coming in. It’s brilliant for camping or leaving the vehicle standing for long periods.

Apologies - on re reading I should have been clearer that any PSU would work and that the PCB based ones were a suggestion if you wanted to tinker as I don't think many people are aware of them

Hopefully you're getting some good van time in over the summer
