Leisure battery upgrade

[Jonesy68]

Hi guys I have had my LB fitted for a few years now and the original 105ah isn't really big enough so thinking about Lithium 200ah but looking at all the well known brands I'm not sure if it will fit where the current battery is. Any recommendations? I don't really want to use the other space under the passenger seat as I usually store my inverter there.

Measure the existing battery, then make a brew and start hitting the Internet. Most sellers list battery dimensions somits easy to see what'll fit.

Going from 105Ah AGM to 200Ah lithium is almost a 4 fold increase in usable capacity.
Perhaps less than 200Ah lithium is enough?

105Ah LiFePO will fit in the same space as the AGM

I'm not aware of a 200ah lithium that will fit under your seat other than the dedicated seatbase batteries .
230ah seatbase is around £650- £750 'ish

100ah lithium might surprise you, very small but effectively double the capacity of your current battery.

As my girlfriend points out size is one factor, but keeping it charged is the challenge.

You won’t get a 200ah battery in there but a 105ah lifepo4 would fit easily. Twice the usable power of your current battery when it was new. Would that be enough? Or you could go for a 230ah seat base battery but you would need to move the other bits under the seat.

My setup:

The Roamer 160ah fits in a seat base?

Or the Fogstar/roamer 230ah

...

I run a Fogstar 230ah in one van,

And twin Roamer 230s in the bus.

I had a 105ah same as @ginkster and it was good for at least 4 days without top up running my fridge, interior lights and smart TV. A quick 30 minute top up off the van was enough for another day easily so going for a drive to do a bit of shopping was enough for that.

Yes I think I'm going over the top (not for the 1st or last time!) with 200ah.
Like the look of the fogstar 105ah.
So do any of you guys have a Victron dc/dc, if so do you use the default Lithium settings?
Nothing else I need to change is there?

I had Renogy and recently swapped to Victron. Mainly due to size as I updated to seatbase battery. Standard settings and works just fine. I find set at 30ah is fine for me as its a daily driver so it's usually topped off every day. So much so I turn off the charger some days to allow it to discharge down a little.

I have setup a custom profile using the Victron settings provided by Fogstar on the FAQ page. The default lithium setting is fine too.
