[QUOTE="stevewilko, post: 644005, member: 8651"] Hi, if you can help please. 2 x 100AH AGM replacement. (holding 12v overnight still, but useable amperage is low and relying on solar PWM feed daytime charging) I want to buy 1 x LiFe PO4 @ 135AH I have 380w solar. 20 amp PWM. Need MPPT controller to suit LiFe PO4. How do I determine the best battery (brand) to buy? How do I determine the AHours correlate to the promoted / advertised capacity? Which Amperage MPPT is best suited? Care to nominate a proven manufacturer to assist me make an easy decision? I think to not buy the cheapest, and I do not have greater demand than 240v / 400w x 1/2 hour rice cooker and then it is only laptop, phone and 12000millivolt powerbank, gps etc. This means I do not want to spend $1000! Not being trained in electronics etc , I do have a small dometic condenser fridge that pulls 8.333 amps and I only have ever run it on gas. Perhaps I would like this to be part of this equation. I have crank battery isolation with 12.7v minimum feed to house battery available while driving. Thank you, Wilko. P.S. I cannot fit 200AH as the dimensions won't fit my battery box. I do not see greater than an 135AH battery choices neither. (should I install 2 x 100AH LiFe instead?) I am probably predisposed to an eBay purchase for convenience. [/QUOTE]
