If your existing system does what you need, stick with it. P The only thing I'd look at is using EFB type lead acid battery. Still a wet cell type, but more resilient to being discharged. They will work fine with your existing alternator and split charge. A lot of stop/start car batteries are moving back to wet cell efb from AGM as AGMs haven't proved as durable as expected. 2007 110 TDCi Station Wagon XS

if your existing system has worked fine and covers your needs then i would replace with the same. not sure how many years its done though?
we run an agm leisure battery and its fine for fridge and lights at night etc for 2-3 days (depending on use it does do more) eve in hot weather trips. |

It is currently an agm battery and is at a guess 7 ish years old. I used to get 2-3 days out of the fridge camping but now it is a few hours.
It would be handy if I could get an extra couple of days or charge it without the engine running though. 1995 300 Tdi Epsom Green - It's a keeper. Wide Track Sankey- In bits- Gone to a new home M0XQS |

I’m thinking about upgrading mine, dc dc charger, inverter, lithium battery, induction hob and perhaps small fridge with water pump, lights inside and out and the night heater. Possibly a small air fryer. Not sure about the solar panel. It’s a one person camper. I’ve currently got a vsr and second lead acid battery which runs lights and the heater, which is fine.

that's done very well. i would keep the same maybe goto a bigger amp battery if you have the space.
the dc-dc and lithium battery is a great set up a few friends have it and it will run a coffee machine, hot plate etc without issue. unless your staying in one place without running the engine or solar top up it can be a fair chunk of money to spend. i run mine without solar at the minute as i dont want to spoil the roof tent with panels. or you could do what a lot of aravan folk do and take a small silent generator to top up when off grid and provide 240v as well |

From my research, you’ll get 50% of the available capacity out of the lead battery, 60% from the agm and 90-95 % out of a li-on one. Also the more expensive li-on’s have a built in heater, so they’ll charge below 5 degrees. Apparently they’ll last 10 years too. But it really depends on what you want from it and then how it’s charged. I found the solar panel on our sprinter van to be more effective at charging than the dc-dc charger and of course it works when stationary.

Re an EFB as opposed to an AGM. I agree with Bluest, with our old school alternators an AGM will not last or perform as it would with an alternator designed for AGM batteries. An EFB is a far better and cheaper choice. The Varta LED range is ideal, being a dual purpose leisure and starter battery with minimal self discharge. |
