Doubly-fused charge cable on double batteries?

[Pskhaat]

Wiring my aux battery. Trying to avoid getting fried out like I did in years past. https://expeditionportal.com/forum/threads/traveling-in-a-fried-out-combie.28802/

If the charge cable ends up grounding (it happens to me, see above) ¿may I assume the benefit of fuses on each battery as to not short the positive from either side?

Yes.

Absolutely yes. A fuse for every current source, lest your carefully installed wires become low-efficiency heating elements and highly efficient voltage-to-smoke converters.

Which...they do Always.

Blue Sea makes a fuse that goes right on the terminal of your battery. If you haven't seen these, they really are super slick.
