有D差機說明書咁講呢 (hyperion):
"It is critically important that you use either a fully charged 12V~24V lead-acid automobile battery (or better, deep-cycle marine battery) - or a high quality AC-DC power supply in the range of 12V to 28V DC output, with minimum current rating of 10A. When charging high voltage batteries at high current (charger output 360W) the AC/DC Power Supply (PS) should be 15V minimum with rating of 350W or more, to insure reliable performance. Note that PS load control features DO allow you to use lower-rated power supplies reliably, but that total charger output wattage will be limited accordingly. (See details later in this manual).
If you have any trouble charging after confirming that input and output cables are properly connected and of the proper materials, be sure to check the charger on an automotive battery. Many problems are associated with poor quality or inadequate switching AC-DC power supplies. Use PS Load control as needed to reduce load on your PS, or upgrade your PS."
