Why almost all 48volt to 12 volt converters are TERRIBLE and how to install the RIGHT one! I will show a tried and true voltage converter that works unlike the Chinese ones that can be dangerous. This Chinese converter pulls 13 14 milliamps all of the time with no load. The new upgrade pulls only 3 milliamps all the time with no load. so that is more than 4 times less. I know these seem like small loads but over time it drains the batteries, especially lead acid batteries. This parasitic drain gets worse as the capacitors degrade over time.
