im in the same situation as you, my biggest battery is 5ah at the minute and the grinder goes though them fast, I currently have about 6 batteries and I drain them all using either sds, die grinder, angle grinder, impact driver etc. 2 rapid chargers and a bestek 400w inverter would cost the same as 1 12v charger and will charge them much faster, im not sure if it means I will need a second 12v battery and split charge yet because that will start to bump the price up a further £150 at least id say, I will see how I gt on just charging them with the van running, if I find I need to charge them with the van stationary then il go down the route of a second 12v battery.
You don't want to be leaving the van running for 40mins a time to charge them. That's going to soon add up to a lot of diesel and extra servicing costs plus the chance of somebody nicking the van.
If you are driving about enough between jobs then you could charge them when it's running anyway.
Another option is put a low battery cutout isolator into the van battery and leave them charging all the time plus add a decent size solar panel onto the roof to keep the battery topped up.
My last van had a second lesiure battery on a split charge but they only lasted a year or so at €100 a time to replace.
I get through 2x 6ah a day on the grinder.
I have 2 drills doing 4mm and 8mm holes in steel with 4ah that will do a week in the 4mm and 3-4 days in the 8mm.
I am thinking of spending £200 on 2x 12ah battries so I should only need to charge them every 2 days. Put the 6's into the drills and I will probably only have to take battries in for charging 3 times a week at most.
It's easier for me to carry them into the house and chuck into chargers on the desk than mess about in the rain trying to plug power cables into the van.
You will need one hell of an inverter to run a welder, you might be better off with a genset welder and use it as a generator to charge tool batteries if you need to chuck them all on at once.
quite complicated when you get into battery run times but if I worked it our right 2 rapid chargers totalling 310w to run on a 100ah leisure battery means I would get 1.85hours of run time before the 12v battery no longer has enough power in it.
Don't do that on anything modern!I'd add a second battery, and a relay powered by the alternator warning light battery (little wire from alternator) so it's joined to your main battery when the engine runs (means you won;t run your main battery flat)
Transit battery setup depends on how they were specced when ordered. They can vary from a single small enhance flooded battery, to a dual AGM battery setup.although... what kind of van is it? iirc almost all transits have a split battery system from new now (might just be the long wheel base ones, all mine do)
Just had a look at a Bosch charger,
I have fitted a fair few inverters into work trucks for people and the main problem I have found is most inverters have a low voltage cutout to make sure you can still start the van again.
This means they will switch off at about 10.5v so if you do fit a second isolated battery you can still only use the top 10% of the power in it. (Or 10ah from your 100ah battery)
Biggest system I fitted was 3x leisure battries with split charge, bigger alternator etc.
The guy wanted to run a 4" belt linisher 1/3hp or so.
It ran for maybe 4-5mins before the battery alarm kicked in and shut it all down and that was on brand new batteries.
The inverter was a demo thing from a Ring rep who was trying to get stuff into our market so they took it back and adjusted the cutoff down but the overheat alarm would then kick in before the linisher stopped.
Got it to about 10mins run time in the end but this was halved under load/in use.
