While hunting for the water leak the other week I removed the rear card which was water marked. Sorry, no photo of before. Gave it a clean today but didn't get rid of the watermarks beyond about 50%. Quick look on the net and white vinegar/water 50/50 mix, spray, let it soak, dab it off.

Unbelievable! Keep it in mind for your own boats & vans.

White vinegar is our go-to stain remover. My rugby tops suffer from grease stains.

Proces is: spray liberal amounts, chuck in washing machine set to 60℃, set delay time to 1hr so the vinegar can do its work.

The benefits of LFP over Lead are multiple:
- Better energy density
- Much longer lifespan
- More efficient
- Deeper discharge

That "300Ah" LFP will be happy discharged to 10% or lower every day. However a similar Lead battery will age quickly if you discharge it lower than 60%. So the additional cappacity is way more than it might seem at first glance.

I'm sure the self-contained LFP incloudes a "solution" to prevent it chrging quicker than the altenator can comforatbaly provide power. Particularly as this can simply be a 20mΩ resistor. In fact the BMS probably imparts this resistance without even trying!
I'm definitely going LFP for van 2 - eco-worthy have a 280Ah one for just over £400 currently!
I'm very much looking good forward to seeing that. I've deliberately not allowed myself (LFP) it this year. I like to live in some form of artificial scarcity to keep the value of things in view. Any idea when Rich? Ecoworthy often do sales, might be worth tracking the price?
When? Quite soon is the idea. Trying to decide what is most important size & height & features wise for the new van - want to be able to stand up, to have a fixed bed, with garage for mountain bikes underneath. I'm currently looking at transit L3h3, as a kind of natural progression from my transit custom - still (just) under 6m long, but with plenty of head room, as I'm 6'3"

L3H3 Transit really is enormo!

Tough to park and not much fun on lanes. I know you're a giant, but do you really need something that big?

I know what you mean, kind of.
My current van is a Custom L2, which is 5.4m long. I haven't found it bad for parking or fitting down lanes over the last 8 years - So, the L3 is 0.6m longer (which will mean carpark spaces are more tricky) , and only a few cm wider. Obviously much taller, which is actually my main concern in terms of driving / fitting in places - wind could be a real problem, and overhanging trees!!

I did think about getting the high roof custom L2H2, so no increase in 'footprint', but it is only 1.75m high inside, so I'm still stooping (1.89m).
Our aim is to have more organisation inside, as well as the fixed bed and the MTB garage, so the only solution so far is to get something bigger (I'm definitely NOT going for the L4 version, which is another 0.7m longer!! - that is getting a bit silly :lol: )

A nice few hours.

Utility cupboard now has a mirror and a doorstay. Cut out a couple of floor mats from No1's old Zoe EV for door entry I to van.

Ran up the 500W heater on ehu.

Image

Then realised I'd rather export that 500W so switched to the 200W ceramic heater out of the Bongo and ran it up offgrid.. Believe it or not its actually getting it done. :)

Image

Image

Fridge test on ehu ongoing!

Image

Hoping to get away next weekend so swmbo can feel the difference in space and mod cons compared to the Bongo.

Image

Image

Swmbo working magic soon. Work surfaces are beginning to reappear too. :D

Water side all tested again and topped up. 500W ehu heater is on and offgrid kettle & radio are working well. AAA's for the three led pir lights all good too, charged from offgrid.

SWMBO bought two offgrey bound carpet runners from Aldi middle aisle at a tenner each. :D
They're excellent underfoot, such a difference!

Radio gets an offgrid charge too and runs at least 12 hours blasting out classic fm.
