Hello, I need to find a battery charger able to deal with an AC input that is quite unstable in terms of voltage and/or frequency - it comes from an old hydraulic turbine that feeds a very small village. Now with low water flow its output is irregular. So, the question is, in this situation which one is the best battery charger for flooded lead-acid batteries, and which one would be the best for LiFePO4 batteries. Thank you very much!
