I’ve been using this in my camping rig for about a year now and I must say it is an impressive piece of kit. From sub zero winter excursions to Sahara summers the M30 has not skipped a beat and is the perfect companion for the Lithium battery I use. After my long term test here are some of my personal pros and cons: Pros All in one unit – no “addons” required including support for Solar Hugely informative graphical control panel Input terminal block is detachable – removing the unit doesn’t require disconnection of each individual input and output. Very useful if you don’t want to leave it inside a vehicle when not in use. Compatible with every battery technology imaginable including LiFePO4 Cons: Its huge! Its not weatherproof which limits mounting options Stats are instantaneous and not averaged – so things like “days left until flat” depend on what is running at the moment you look at it. No way to export data – the controller provides some very useful charge and utilisation statistics and it would be great if you could export these to keep a long term log. Would I buy it again? Yes absolutely
