split charge query

[mikeymike]

Hi All,
I am currently converting a new custom to 4 berth camper.I have converted many vw t5.This is my first transit and just love it.My question.I plan to put a leisure battery under drivers seat and use a durite split charge connected to main starter battery to keep it charged up to run fridge lights ect.I have done this many times on the T5.1 but had a problem on a 2016 vwT6 (as it had a electrical regeneration system).Will I have any problems doing this on the custom ??

Simple answer is Yes it will have problems, there have been a few posts on this topic, I run an inverter for charging tool batteries and my leisure battery never fully charges, if I charge the battery weekly it's just about usable.
I've looked at Sterling battery to battery charging systems and despite the cost it's really the only way to get a 100% use ability, someone has fitted one on here and so far I haven't seen an update on how it's working. I've got to sort my system out in the next week or two ready for the pre season fun and games.
I will try and post a link to previous threads..

I'm well confused...

I've looked at the links and the video, thank you posting them, but I'm still none the wiser. Other than it looks like I need to spend £240 on a charger?

I've got twin batteries with a third battery in the back to run my 240v. I had it connected up last week and the third battery never seems to charge. It's on a split charge relay system, but I'm not sure which battery up the front it is connected to, which should it be to get it to charge the rear battery?

Looks like it wasn't worth me getting the split charge system hooked up, I might as well just plug my 3rd battery in at night

Hane all the customs got smart charging or is it after a certain year?

[moley551]

I think it's a Euro5 and 6 thing so will apply to all Customs.

Great that's gonna be expensive then thanks

From the video, the battery SHOULD get to 80% charge, but I've only ever seen mine drain down and top up on my battery meter. I think I will just charge mine up every week for how little I use the 240v, I'm thinking about disconnecting the split charge system completely in case the increased voltage damages the battery, if and when it does charge it.

this is what you need.

That's too much money for my needs.

cant you fit a separate solar charger and a panel on the roof? just a thought, might be easier.

most campervan builders use this flexible type and use either high strength double sided tape or silicon adhesive to stick the panel to the roof. its a much lower profile than the solid panel type and is easier to mount.

My leisure battery was about 5 years old, the run time has declined despite showing fully charged, so gave up and bought a new battery it's now working properly again.
