Mr. Wright's question about mobility scooter batteries has poked me into
asking this again.
1) I have a 12v towbar winch, which I need to cable to the front of the
2) This vehicle tends to sit for weeks unused, so I'd like to be able to
plug in a charger in the garage and run a cable out to the car to put it
on charge in the inevitable rain.
3) I seem to be the only family member with a charger. Last time I had a
flat battery I had to ring round to recover the chargers. I seem to have
lost the 2 mains extension reels that they borrowed with the chargers.
It seems to me that something like a 30foot length of cable with
something like Anderson connectors on each end and a few adapters to
croc clips etc would be a useful thing to have handy. I gather Anderson
connectors are used to charge mobility scooters.
Winch current draw depends on the load, but apparently can range from
10A up to 90A for short periods.
2 questions: These connectors are said to be reversible. I can't get my
head round whether there could be any problem if they were lent out. If
the extension cable were connected the wrong way round, it would
presumably have + on black and - on red, but this would be corrected in
My guess is that either 4mm 41A or 6mm 53A stranded cable would be good
enough for the intermittent winch current in the open air, but I'm not
clear what size connectors would fit, or how easy this cable would be to
carry, store or handle.
Has anyone done this sort of thing?
