Cllena 30A 360W DC DC Buck 360 Waterproof Transformer, Step Down 12V DCGregor Convverter, 36V/48V to 12V Converter

Wiring: OUTPUT+ to LOAD+, OUTPUT- to LOAD-; INPUT+ to BAT+, INPUT- to
BAT-Note: * Never connect to solar panel, PWM/MPPT charge controller, inverter or wind turbine. * Never charge the battery. Keep good air convection. * Never reverse the polarity. * Use the enough big cable to avoid the voltage drop.
Application: 36V/48V DC battery as input power to 12V DC appliances as output load.

Voltage ConverterQuestions: How to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/ 0.8 = 12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/ 0.5 =20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.
