Hi to anyone interested in my feed back.
I have run one of these for exactly 15 months now, installed May 2022.
Initially on intall the most immediate observation was the speed my diesel cranked and fired into life, brilliant benefit straight off aside from wieght benefit.
Have utilised it to winch with, but nothing as extreme as suggested here in a comment.
In regard to wiring query for second battery.
The only sticking point is:
You need a difinate seperation of batteries once vehicle alternator isn't charging, hence I installed a ignition sensitive relay, when ignition on = motor running relay joins batteries, ingnition off, relay seperates batteries.
Why? Voltage regulated units that are usually utilised to seperate batteries generally cut in over 13.2v joining batteries and drop out at 12.7v seperating batteries.
Issue, at 12.7v the 1420CA Pro is basically flat and can't be relied on to crank/start your motor.
So, if you utilise a regulated voltage seperation device as I was, (Redarc 1225D) I just placed the relay prior to create a definitive seperation at high voltage.
Now don't see this as a draw back, it's certainly not been an issue for me, the battery as a starter/winch has been totally brilliant.
For the record, I utilise 3x Itech 12v 54 amp lithium as auxiliary batteries, am I happy with my setup, 100%.
Hope this helps with queries.
Oh. To Itech Worlds credit, I was asked if I had auxiliary batteries on purchase of 1420CA Pro and was advised I'd need a definitive seperation, not to rely on the 1225D.

Great video, I have ITechworld 120 in my vehicle as well, so much better starting my diesel and accessories

I'm getting closer to getting one of these. But not sure how to run all the wire's from my dual set up.

It would be great to do a proper winching demo with this battery, with a current meter on the winch cable. ie. L4 in park with park brake on up a slope.
