Hey there, presently I'm using this circuit here: 12V powered, 12 V battery charger to charge a 12v 5ah SLA battery. It takes a 12-15v input and uses it to charge lead acid batteries. At the moment my input is a 12v AC-DC adapter but I've been looking to also find a cheap solar alternative. I found these: **broken link removed** and was wondering if this would work fine with the above circuit for charging a 12v SLA if I was to wire 4 panels in series for 14.4v (on a sunny day) and use it as the input.
