Each to their own lol.
So no answer other than LOL because my pumps and battery should have failed? And yet they don't. Must be irritating to some that some people get through more flow controllers than I get through pumps.
Mate you crack on if you're happy. I think I have more info about pumps & batterys etc but we'll just agree to disagree. My pumps & batterys will last longer with a controller & a good charge routine.
Well tell me about them. If it works then explain.
How long have your pumps and batteries lasted?
Mate i don't know exactly how long. Years in both vans. I don't want to get into all this. I can't type that quick & it's frustrating.
But if a controller allows your pump to only be working at say half power it will last twice as long in theory. It will also use only draw half the power thus draining the battery less. With a decent leisure battery & charge routine (split & bench combined) you'll then be taking less deep cycles out of your battery. Read up about battery cycles & not draining them below a certain percentage on the net if you're not convinced. It makes for the most efficient system.
Plenty will get by with their scrap yard starter battery or connect to vehicle battery & say they never have a problem I know but it's just not the way to go.
I can't type any more. My fingers ache.
