F PACE BATTERY CHARGING FROM BOOT ( CTEK )

Connect the positive on the CTEK to any convenient positive terminal that goes direct to the battery, or if there's provision direct on the positive battery terminal clamp, preferably add a 10A fuse to this wire for protection. The negative should go to any convenient chassis point, not the battery negative. This way the CTEK charge current flowing into the battery will still be monitored by the BMS, which is incorporated into the negative battery cable.

The BMS is the small black box on the negative lead near the clamp. The 2 small cables, 1 is +ve the other CAN bus.

@diesel's diagram is perfect and spot-on. He's indicated the ideal locations for a charger to be connected. Using the +ve bus bar and a convenient chassis point for -ve will still be fine. I don't have a permanent connection for my CTEK on the F-Pace (I do on the XKR) as I use the jump-start terminals under the bonnet. No doubt these have a higher resistance back to the battery than the ideal points to use, however it still recharges just fine.

Should you ever need it - If the F-Pace battery should ever die and you need to open the tailgate, access the car via the passenger side emergency key hole lock. Unlock the rear doors by stretching over. Fold the rear seats down, climb into the boot area and on the tailgate latch is a small hole to the right. Insert a small screwdriver and move it to the right, this will manually release the tailgate latch.

CTEK make a direct connect cable for this exact purpose, directly connect it suitably to the battery and leave in place. I have fitted this to the XKR and it hands about discreetly in the boot. I use a 2m CTEK extension cable, connect to the direct connect cable, route over the tailgate aperture rubber and can easily close the tailgate over it.

I use the extra 2m cables as the CTEK is mounted on the wall in my workshop close to the shutters, and when connected to the XKR the cable can happily trail over the floor then up into the boot. The F-Pace lives just outside the workshop in the courtyard and the extension cables enable the CTEK to be connected to the under-bonnet terminals with the croc clips. I can route the cable between the headlamp and bonnet then close it. Any damage will just be to an extension cable, but they seem very durable anyway, plus careful handling all should be fine.

In my XKR the CTEK charge socket is just left loose in the boot after feeding the cable so the boot floor panel can trap it in place, with a short length exposed. I don't have a permanent connection in the F-Pace as the car is used more often than the XKR but I use the under-bonnet battery connection points when required.
