Very Inexpensive Battery Maintenance Charger
1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but ...

Those little chargers IMHO are garbage. The ones with separate TRANSFORMER and regulator circuit. Too many regulator failures. But with the regulator cut out of the circuit stick a 3 amp axial diode inline with the positive charge lead and the transformer gets tamed. Recheck voltage. If need suggests it add a second diode this time a shottky to further reduce voltage by .4 volt. Ideal is 13.3 to 13.6.
Mex, would this work the same if trying to lower/change the voltage output range of a power supply unit such as the meanwells, megawatts, or even my turnigy? For example, my turnigy has an a adjustable range of 13.6 - 18 volts. Could I change that to say 11.6 - 16 volts, or would it only limit the upper end of its output range? so, 13.6-16v?
Thanks!
