Smart charge wiring help pls.

[davchad]

Hi All.
Due to the Covid probs i do not use the car as much.
I have bought a Ring smart charger to keep the battery topped up.
I would like to keep it in the boot permantly.
What cable amp and fuse would i require to run from the posative jump start point
to the boot.
I have some 27amp not sure if it would be suitable.
The lenth would be 3.5m or 4m.
The charger gives out max 12v.

Thanks for your help.

David

Cable you have will be fine, BUT it is essential that you include a 15A inline fuse just before you connect to the jump start point.
