Saving my 12v batteries with a DC-DC Boost Buck Converter!!

I found out that my 12v battery charger was putting out nearly 16v while charging my batteries!! They were literally sizzling inside! Here I use a DC-DC Boost Buck Converter to lower the output to a much more sensible and safe 13.80v. Here are some specs on the converter I purchased: Input voltage: DC 3-15v Output voltage: DC 0.5-30v Input current: 3A (max) Power: 25W (max) Conversion Efficiency: 95% Switching Frequency: 150KHz Output Ripple: 40mV (max) Load Regulation: +/- 0.5% Voltage Regulation: +/- 2.5% Operating Temp: -40c to +85c Dimensions: 48mm x 23mm x 14mm approx. Open Short Circuit Protection: Yes Thanks for watching, and please check your chargers output!,
