Questions: Why some people perfers to 13.8V? There is voltage drop due to cables or old battery, then 13.8V is perfect to work for your 12V load as the car audio or other loads will get enough voltage to run. What is ACC? ACC works as a switch when your vehicles have ACC to avoid battery drains. How to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.7=14.28A 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.
