F225 Isolator charging coupler

[Gigman]

I believe there are more than 1 coupler for this engine. One of the couplers comes with a fuse, is the fuse needed with all of these couplers? The other non-fused couplers are different lengths, do they come with battery lugs attached? Thanks, Lou

Either one will work, you should put a fuse inline. Yes they do have battery terminal.

Isolator cable

Isn't there one that has the fuse as part of the cable?
Will these isolators work with the 2 batteries in parallel? Thanks

MAR-69JIS-0L-ED Isolator lead with 50A fuse. Connect Isolator lead to positive terminal of second battery, connect a jumper lead between negative terminal of battery 1 to negative terminal of battery 2.
