We are just about through our winter here and starting to plan ahead for the coming caravanning season. We have a 2008 Swift Challenger 510 which I tow with a VW Touareg and am very pleased with both. I am in the process to upgrading the current battery system to LifeP04 Lithium which I have been thinking about for a while but never quite wanted to deal with converting the rest of the caravan electronics to make it all work. So far so good however I would like to replace the lead acid charger in the NE2006 CWS controller with a Lithium charger but have not been able to find good info on how to do this, hence me joining your group. I would greatly appreciate any pointers or links to discussions that might assist. Thanks for having me, regards Mike
