Charging Lead Acid and Lithium

[RichieM]

Hi, Apologies if this has been asked before but a bit of searching couldn't find an answer.
I've just upgraded my old AGM leisure to an eco-worthy 100ah Lifepo4 battery. After some fiddling with settings it's been great. Sitting on a festival site for 3days with no EHU, fridge working great and 200w solar panel keeping lithium battery charged. (Does help having some fantastic sunny days though).
My lead acid starter battery is struggling however and currently down to 12.2v

I have all Victron bits. 100/30 MPPT and Orion XS. I also have an IP22 when on hookup. I had hoped that if the lithium battery was being charged the starter would too.

I have an Aferiy powerbank that I did connect to the EHU to see if that would also charge the starter but no luck.

Have I perhaps got a setting wrong somewhere?

Cheers

You don’t have the necessary hardware to charge the starter battery. Search the forum for Ablemail AMT 12

I have roughly the same setup and no, it doesn’t charge the SB. I fitted an ablemail MT 12 which trickle charges the SB from the LB.

AMT12-2 Trickle Charger charges Vehicle Battery from Leisure Battery with Solar Charger /Mains Hookup or only a Secondary Battery - Ablemail Electronics

The AMT12-2 Trickle Charger, Battery Maintainer, Battery Equaliser keeps Vehicle Battery charged during Vehicle, Boat & Motorhome inactivity.

Aha, looks like I was flogging a dead horse constantly fiddling. In the shopping basket for next week now. Cheers guys.

Third vote for the Ablemail. Brilliant bit of fit and forget kit. Simple to fit, tiny, effective and reasonably priced.
