First you need to identify what your new van's actual charging cycle is. In other words, how smart is you van's charging system.Hi guys. Have bought a euro 6 van. I understand that the split relay differs from this to earlier models.
Will it damage the van to run on the one that comes with a window cleaning warehouse system? Or should I upgrade this
I have a 62 plate Peugeot Boxer. The alternator charges at 13.9v all the time. I could use a vsr but the maintenance free leisure battery needs 14.2v to charge it fully.I have a B2B charger in my 2018 dispatch. Just bought a 2014 Doblo and will be fitting a B2B charger to this also. I haven't had to charge my leisure battery since installing the B2B charger. My new van isn't euro 5 and doesn't have regenerative braking but I think the benefits of the B2B charger far outweigh the costs.
To be fair you were the one who gave me the idea too. I love that B2B charger, can't fault it. I remember you saying you'd install one of those even on vans pre euro 5.I have a 62 plate Peugeot Boxer. The alternator charges at 13.9v all the time.

I can set my Sterling B2B charger to the output voltage I need. I set the charge voltage to 14.6 for my old flooded leisure battery.
.... and to be fair it kept up with recharging the battery just using a couple of pumps a day. During the summer I hardly 'bench' charged my leisure battery at all.To be fair you were the one who gave me the idea too. I love that B2B charger, can't fault it.

That's a great idea. Charge both batteries at once, nice.I have a fitted the charger lead on the starter battery input side of the B2B charger. My charger then tops up the van battery at 13.9v (the charger's output) as well as the leisure battery at 14.2v. (The Sterling unit boosts the charger's output from 13.9 to 14.2v.)

I just disabled my smart alternator, no issues at all so far.
The charge only ever sits at 14.2v when running, I assume when I did this the ecu was learning the change from the battery monitor system and besides my van only ever runs for a maximum of 20 minutes at anyone time so I think it's perfectly safe, thanksIf you have a sealed leisure battery (maintenance free - no caps to unscrew to top up water levels) then 14.6/14.7v is higher than the recommended charging voltage for these types of batteries.
If the van has regenerative braking then the alternator dumps charge into the starter battery at around 17 volts which is far too high for a leisure battery.
It obviously works for you but it doesn't appear to be a fix that is a popular solution on the internet.
