Right I'm totally confused!
I'm needing to get a pump box for a van system. There are lots of options and batteries etc so just a few questions (excuse my stupidity)
A.h- What is it? I presume a 110ah battery last longer than an 85ah? What Ah do I need for a van system??
Also, a split charge thingy looks a bit confusing, and I'd be happy to charge my battery in the house at night, does anyone do that?
My WCW backpack lasts for ages (a good 3/4 day's work on a 3hr charge!)- so can I not just put in a WCW backpack battery into a pump box and charge it with my existing charger? Or would a 100psi pump really drain the small battery alot quicker than the backpack pump?
Thanks in advance!

You should get 3 to 4 days out of an 85Ah leisure battery,that's plenty.I've been wfp for over 4yrs now,and never needed anything bigger than that.I have an Exide 75Ah that's over 2yrs old,and i'm still getting 2 days out of it.A wee tip,get yourself a smart charger that cuts off when the battery's charged,and always put it on a slow trickle charge,the battery will last longer!

Ok mate, are these 85ah leisure batteries lead type or gel ones? Does that charger thing plug in via your standard house socket then?

Lead acid batteries are fine,and you'll get a good charger from halfords for about £60,but mind and tell the assistsnt that it's a smart charger you're after,so you don't get any old sh!te that'll fry your battery.The new tank arrived today,so you can collect the old one anytime after tomorrow mate!

and the AH stands for amp hours. Ie if your pump draws 5amps (which mine does) and you have a 85ah battery,then the battery will last 17 hours constantly running (85 divided by 5).

Ok thanks pal. Will see what weather is like. I'll have to work if it's dry, so might be next week if that's ok? I'll drop you an email and let you know anyway. |

That's with the pump running flat out. If you use a digital controller the amps drawn are drastically reduced. I've run my pumps direct from the vans own battery for 8 years with no problems, currently a Bosch 63Ah. Two things that will determine how much power the pump will consume are- type of flow control & hose internal diameter. The smaller the hose the faster & harder the pump has to work to get water down it meaning more amps drawn. If you use a bypass system, or even no flow control at all, then the pump is drawing maximum amps all the time it's running. |

I have just converted my van to a split relay with a heavy duty battery to go with it .This was because i was fed up with recharging my batteries overnight and eventually them going flat and needing to substitute them durring the working day.
Its been working great , and supplying two pumps .
