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

How does this go with the charging systems ionics install mate?

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

A dc2dc charger? I charge in my house with the charger that fogstar sell?

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.

If you can mains charge each night you should be fine.
A dc2dc charger is for charging while your engine is running - probably not needed if you can mains charge each night.

"Taken in". If you mean take into the house for charging, then Fogstar don't recommend doing that with their lithium batteries.

The last starter lead acid battery I bought for my van came with instructions to open the packaging outside and charge outside if necessary.

Victron, Sterling and Renogy are the main dc2dc players.
Personally, Sterling is great but programming the unit can be very confusing.
Victron can be programmed via the app on your phone.
I know nothing about Renogy.

The Renogy dc2dc is mega simple. Just 1 button on top to cycle through the battery types, that's it. Unless you get the bluetooth module then you have more settings to play with, like current limiting.

I have the 230ah fogstar drift, charges via Victron TR smart 18a isolated B2B charger in van, and the mains charger is wired in in case that fails.
The 230ah I’ve discovered is way over spec! Could easily have got away with the smaller one, I’m running 2 reels and pumps and it barely takes any percentage out with two pumps running all day on one job. With the usual stop/start day it’s always 100%.
Shop around - I’ve got a trade account with 12v planet and got about £90 off rrp, if you get one the instructions say to fully flatten and charge 3 or 4 times to help the BMS calibrate which I did.

This one is its own independent unit that plugs into the streamline compact system. In all fairness it's never been used so I've only charged it to test it now and again. It's one of those purchases that seemed like a good idea at the time. The part of the system its located has a flap and the battery has a handle and comes with a charger made for taking it inside to charge. I believe that suggest it has an 8 hour life.
