Thread: Winching on just one battery?!

Looking at Runva:

12000lb Competition:
RUNVA EWX12000 Winch Package -12V or 24V | Trade Me

or
9500lb
Runva Winch 12V 9500lb *OFF ROADER* | Trade Me

What do the boys and girls with winches think?

You don't need dual batteries to winch - it can be beneficial if you use the right type of second battery, but is far from necessary.

Winches typically have low duty cycles for thermal reasons so your battery will have some opportunity to recharge anyway.

I'd suggest you check out the Mako Avenger winch in a 9500 - iirc you have a 90? A 12000lb winch is typically a 9500lb winch with a higher reduction gearbox - it'll have plenty of pull for your rig and be faster too.

Should be fine with one battery but those Runva winches have big amp draws... the avengers are better in this regard but achieve it via a slow line pull in comparison to other winches.
I'd try and find something between the two ie a winch with reasonable speed and an efficient motor.

Ok - good to hear. Haven't seen the Mako ones on NZ so will look them up. Yes I have a 90.

I originally (27 years ago) had two batteries on my RRC in case I stalled in the middle of a river, etc. This would let me winch out with one battery, then attempt to start the motor with the other. Eventually I went back to one battery, and haven't had a problem running my winch, which is a Warn 8000lb.. Like you I winch a couple of times a year, and I leave the motor running in case of an excessive battery drain. The hand crank (1981 RR) would easily start the motor on a low battery, but when fitted, the winch obstructed the crank hole. Catch 22!

Tikka,

The Mako Avenger winch is also branded Kingone TDS Mako Avenger and this fellow sells them in NZ.

I had the "Gold Fish" version in the UK (extra water proofing) from Good Winch and the 9.5 is VERY fast compared to even the Warn's in its class. I can recommend for value for money!

Cheers,

There you go again Lou thank you!

I do abit of electrical work with my job occasionally, and I would suggest this warning also;

If you create a dual battery setup for winching, you will require a different battery than that which would be required for running a fridge for long periods.

Cheers, Adam.

Righto - deep cycle for fridge not so good for winching?
