12v trickle charging

[michal]

Hello, I would like to set up a system of trickle charging of the starter battery but accessed from an interior. Unfortunately there is no easy access to the battery (+) connector (without removing the battery). Does anyone have any idea or experience whether it is possible to use a free fuse connector for low current charging in the fuse box in the leg compartment of the passenger seat ? There is voltage equal to the starter battery voltage so it is connected and very easily accessible from here but I dont know if the charging current applied here could go in reverse direction through some electronics and cause damage. Or is there any (+) connector safely and easily accessed from the interior?
Thank you

I leave the leisure battery plugged in to the normal socket and this automatically keeps the main battery trickle charged as well.

Thats the lucky issue for a classical MP. My situation is different. I dont have the external power socket as this was not installed in Horizon MP as a standard. Moreover I need solution for situations with no access to the power. I will use either fotovoltaic power or transportable battery eg Ecoflow and I dont want to connect cables provisionally to starting jumpers in the engine compartment from outside..
