I've a second (leisure) battery, in my van conversion. It's linked to the main battery via a 'split charge relay' aka a voltage sensing relay. It basically charges the leisure battery when im driving.

The leisure battery is Hooked to a 2000w inverter, giving me 2 x 240v sockets when 'off grid'.

My mate (a carpenter) has the very same setup for charging power tool and drone batteries!

Once you have a way to recharge the leisure battery, and a decent inverter, it's simple enough to setup!

Sounds like a good set up. How much does it roughly cost to set up? Or is there a diagram or plans or anywhere that sells it as a kit

Your power tools probably normally use a DC input (probably 18v) from an AC adapter, fitting an inverter is a waste, you're converting DC to AC and back to DC. You probably just need a boost converter with the right connectors. Something like this...

Basic setup about 300 quid.

Leisure batt (110 Halfords)
Inverter, depends on watts (120 ish)
Split charger. Cables. Fuses. (70)
Cables n stuff.

I'm a total noob, and did all my own elecs...

Be handy to have the 240v sockets for other stuff. And you can run 12v bits (I've lights, water pump, USB port and cool box) from the leisure battery

you can get 12v chargers for power tool batteries :

That's the job sounds perfect. Ye I could do with 240v for other uses too. I'll pick up the gear and try it.

Very good thanks i didn't know they had such a thing. I'm looking for a 54v dewalt charger

Dont get a much bigger inverter than you need they can be very inefficient when running much less than capacity. I'd rather a decent brand used than some rebadged chinese crapola. But the time you're added on heavy duty cable, lugs, fuse, fuseholder, sockets, something like this can be very cheap - get it delivered with DPD parcel wizard for an extra couple of quid:

I have a cheap 300W Lidl inverter that I plug into the dash cigarette lighter while driving. Cheap and charges all my stuff while on the move.

Mollified square waivers are renowned to be poor at powering phase angle fired chargers and appliances...mostly because the angle is 90° and not at all sine.

Easy peasy do with a ~300VA true sine wave. Here's a Studer in disguise.
As for charging the van battery..you get what you pay for.

I bought a vsr kit with leisure battery but I just came across info saying the split charge relays can't be installed on Newer vans, euro 5 euro 6 engines because of newer smart alternator.

Any one know anything about this?

Yurp it'll discharge your service battery.

Get a second alternator or a battery to battery charger if you need diesel electric power.
