if I bought a lithium battery to replace my two 100am batteries, what other costs would involved? I know it’s not a case of just swopping over.

I have 2017 Hymer. Fitted with two solar panels but no inverter.

Could I fit this myself and what should I look out for?

If you buy Lithium’s with built in BMS then you don’t need a separate BMS. The only other items to check are your charger(s), are they capable of charging Lithium’s (both the van charger and solar controller)

If not then you will need to change them.

That’s it.

Fairly new to the market (I was told at the NEC!), are LIFOS Lithium batteries. These are said to be "swop and play" i.e. no other modifications needed. They also seem somewhat cheaper than other Lithium Batteries on sale, at (only) £700 each. Have a look at https://www.lifos.co.uk/ .The stand promoting them at the NEC was "Sail and Trail". Their website is www.sailandtrail.co.uk .

I have no connection with either of these companies, but have been exploring having two fitted to our recently purchased new MoHo, with a 1500 watt pure sine wave inverter so that SWMBO can use her hair drier and tongs! SMC, from whom we are buying our new MoHo are actively promoting fitting these LIFOS batteries, but I have held off for the moment as expenditure is already exceeding budget!

Even with the cheaper, Non E Approved (Legal for road use) Lithium batteries have to have specialised DC to DC charging Very few vehicles are set up in such a way that a Lithium battery can just be dropped in to replace an existing "non lithium" battery

What about these , expensive but lighter and effectively one almost replaces two.

Most decent lithium batteries will replace two conventional batteries power wise for about half the weight

On my new van I took out two 100 Ah lead acid batteries that weighed about 35Kg each, and replaced the 70Kg with two Lithiums that only weigh 15Kg each and gives me double the actual, usable 12 volt power

Wow that is impressive !

less than half the weight and double the power.

Roughly 3 x the price ?

My Son-in Law is a Fire Officer.

His view is still too many incidences of them igniting for his liking....

Not sure how many is too many but once would probably be too much..

That is why we will only sell Lithium batteries that are E13 Accredited for road use. If there were an issue and the batteries were not legal for road use, I am sure that issue regarding insurance would soon raise it's ugly head!

It’s what keeps all the cells balanced and makes sure that in the event that any cell isn’t within defined parameters then it shuts down the battery, it’s just a little box of tricks and in the grand scheme of things not expensive (y)
