Windless cable size, cable manufacture and battery type?

Engine = 4 108 Perkins
Boat 36'

We are about to install the cabling for our Lewmar H3 windless. The run is about 22 feet. It will be no further than 25 and no less than 20. As you can see I do not have an exact measurement. I will this weekend coming.
From what I can tell a 4/0 battery cable would be the size to use. I am not positive though. Can someone say for sure so I can make the purchase as soon as I make the exact measurement leaving room for error?


Lewmar H3 windless

12 volt
Motor Power = 1000W
Max Pull (Kg) = 890
Working Load (Kg) =215
Normal Current Draw = 85A
Circuit Breaker = 110A

Also I was thinking of going with Berkshire marine cable, made here in the USA. Any good or bad on this brand?
Berkshire Electric Cable Co., Leeds, Massachusetts USA

And what battery would be recommended? This battery will be used as a starting battery and a windless battery.

Any bad or good on this maintance free West Marine AGM PWC* Battery, 26 Ah, 500 MCA? It is both deep cycle and starting applications. Price seems ok.

Ok maybe this one would be a better battery choice:

Group 34; 55Ah; 12V; 795CCA; 970MCA. 120-minute reserve capacity
Measures 10-3/4"L x 6-7/8"W x 8-3/8"H
18-months' free replacement, 5 year pro-rated warranty

Thank you,
