Got bored this weekend so decided to rewire my batteries and sort out my split charging.
I moved everything including the winch to the main battery, with the auxillary battery there to support it via the relay.
looks quite busy in the battery box now!!
-
I have never found a split charger powerful enough for competition. Have you used the charger in anger :twisted: :twisted: :twisted: :twisted:
I always find the battery flattens :( and Im running yellow and red optimas.
I have run them in parrallel for six months now with zero problems and in the only instant that I flatten them both. Left it ten mins and the V8 roared back into like :twisted:
-
Is this the best method of auxillary power supply then?
-
I found it was and I know alot of the guys doing the nutty stuff run the same setup. The split chargers cant cope with the power needed to transfer the current over the the aux. I run ALL the mods off the aux (yellow top) which is winches, lights etc etc and then the truck runs off the red. Both are in parrallel so in a way you could say thats irrelevant BUT having spoken to a battery enginneer he said it will make the differnce and as long as you run a deep cycle and a starter you'll get the best set up.
Its such a good set up I put a new loom in and somehow (dont ask....) managed to leave the alternator out :roll: :roll: . Anyway, it ran for three play days at Whaddon and Brickhill with out the alternator and I even used the inch once!!!! Only then did it go flat!!!!

I dont do comps so the winch dont get the heavy duty long periods use that you boys put them thru.
I used to have my winch running off of the auxillary battery but it seemed to lack power - it now is thru the main and I can link the two so that I have two batts powering it - should be much better.
Not sure that this is the best method of wiring but if it works then Im happy!

I have a simular set up on the series. I run a red top optima for the engine and a yellow top for the winch, lights and accessories. I use a powerline split charger and it charges both batteries like a dream.
-
If your never going to really push it I think thats a far better way of running it. At least if you do flatten the battery the car will still start and if its a play day or green lane, waiting 20 mins for it to charge is hardly a chore :wink:
Id stick with the split if you not going to compete.
-
If you are using heavy load on the winch, run two batteries for the winch, and mount a third elsewhere to power the vehicle on longer leads

..and then fit uprated springs to carry all that extra weight... :lol: :lol:
-
more battery power than a milk float!
:shock: :wink:

Talking of which I get my winch fitted on Monday :lol: :lol: . An a couple of long travel shocks at the back. The ones on there at the moment are on full travel just sitting on the drive.
A ton of sand would probably help :lol:
