The battery on my Aeromax dies after a few day when not used, which is an annoyance

I started it with cables and a spare battery, but I am not too sure this is safe for the electronic

I guess, the loom is similar to the Aero 8, and I wonder if any of you has fitted a masterswitch to avoid the issue

If so, I would be grateful to see how you routed the cable,(Especially pass the scuttle) and where you located the switch

I may use one of the switch I still have somewhee in the garage and do it during the Christmas break

Thanks in advance
