Leisure battery charging via tow socket
Hi all,
I’ve recently installed a 12v battery in my trailer tent to power lights, USB sockets etc. The electrics I’ve added are physically disconnected from the battery once the trailer is in configuration for towing. If I connect the leisure battery to pin 9 and 11 of a 13 pin trailer socket appropriately, will the car electrics look after the charging current or do I need something in line (DC - DC charger) to charge the battery correctly? I’m aware caravans have a habilitation relay, I don’t really need this as the loads in the trailer will be physically disconnected, but if it’s a legality will fit one. I’m likely to be changing the car soon (possibly) from a EU3 engine to a EU5 V70 if this makes any difference (possible smart alternator?) Thanks |
