What lithium battery to buy?

WCF

Help Support WCF:

Ideally get a Lithium with a built in heater so you can recharge it if it gets down to 0DegC. Fogstar are a good brand. You realise you also need a dc2dc (battery to battery) charger - Renogy do a 20Amp one for about £100. Plus you need a mains charger suitable for Lithium. As long as you can charge it each night I would go with 100Ah ideally 200Ah to be safe.
 
I have a 150 amp one that runs 2 pumps ,2 reels and 9 kw boiler 8 hours a day and still is above 60% charge at tge end of the day

I don’t have an Ionic’s charging system. My mate who is a marine electrician does all my vans the charger is specifically for the battery , see the above picture
So that picture is your mains charger? Google leads me to believe a B2B charger will also work on the correct setting. I imagine the ionics system doesn’t have this setting as it isn’t for that function but the Sterling ones do.

The older Ionic’s chargers were c tech ones no idea what they are using now ,, you can have a B2B charger but have never bothered with it as when I had Renault vans they said fitting it would void the 4 year warranty, so have just charged them at night by mains electric less than 2 hours and the battery is fully charged
The charger in the picture will charge lithium , lead acid and AGM batteries you set up the charger according to the battery choice I don’t understand it all but my mate fits all this kind of stuff on super yacht s etc

The Sterling B2B chargers can be set in a similar way. The biggest benefit of the lithium is that it can be charged and drained over and over again i believe. The latest battery ionics have me was one a 150ah one. They tell me it can be topped up like the batteries always used to be. Now if only I could find some deionised water 🤔

You can discharge it to practically zero unlike a lead acid or AGM batteries and pick it up with your little finger it’s really lite ,had it a few months now and so far it’s been brilliant, I wouldn’t go back the the huge and heavy AGM ones

I bought a streamline system, it’s only little and serves as a back up. That has a lithium battery built in which can be easily removed and taken in to charge up. It’s a good system really.
