Title: K Systems
Post by: Evan on March 19, 2021, 07:15:39 pm: Any of you guys ever had a k systems fitted?
Having problems with battery as when I use the pumps and electric reels I lose power but if I leave van running it works fine..dont know anything about battery and wiring just wondered if anyone has experienced the same? Or could help with what I need to do

Do you have a way of testing the volts of the battery?

Do you bench charge the battery at all?

It could be totally flat.

Depends how many miles you do. Even if do do a high mileage it is still best to bench charge with a good quality smart charger occasionally.

Two pumps and two electric reels

Post by: Smudger on March 19, 2021, 10:51:38 pm: Your leisure battery requires a top up - unless your driving a good few miles a day it will deplete over several days to the point it can't run the equipment - as it runs when the van is running means the system itself is good
with all that electrically operated stuff you may need a second battery wired in - what size battery are you currently using

I would suggest a Numax 31 MF and a CTEK MXS 5.0 charger to go with it , bench it every night regardless and you won’t go wrong

Two pumps and two electric reels

As P&F says, you need a combo battery - a leisure battery class 2 that also has a CCA rating.

If you are winding in 2 electric hose reels at the same time a standard leisure battery isn't designed to pump out 40 to 50 amps, even if it is for a short duration. You will 'kill' it.

I have a diesel heater running along with 2 pumps. After a hard day and the run home I have a deficit of 13 to 15% of my 105 amp battery capacity. I have to put the charger on every night to fully recharge my battery for the next day.

Running 2 electric hose reels I might even be tempted to look at a 100amp plus starter battery.
