I am looking at modifying our caravan 12v setup. It is a Coromal Pioneer Dirt Road 2009. As standard it came with a Wialki power supply / charger. Now initially I was told this would be fine when we decided to add an AGM. It was for a few years. What I did not realise was this is a single stage charger, so when 240v is hooked up continually charges the battery to a point it destoy's it. One $400 AGM doen the drain, however I suppose I did get about 5 years out of it first.
Now I am looking at alternate set ups so as not to destroy a new battery.
The simplest option as is is to maybe just put a timer on the charger and only charge as required.
The second option is to replace or add a decent multi stage charger. I am looking at the Projecta IC2500. Question is will this work for the whole setup? Should I remove the Wialki altogether? Or run both? eg Run the wialki from 240v staright to 12v fuse box and then run the Projecta from 240v to battery to fuse box or just turf the Wialki and run the Projecta from 240v to battery to fuse box?
Or is a better set up a CTEK 300ms charger to a 250s dual that will also allow for solar?
