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."

不過一般差電應該冇咁煩掛...

Yellow +12V,  2 black 0V (Ground), red +5V, .....

you can set 24v, 17V, 15.3V, 12V, 7V, 3.3V output upto you.

Good Computer's PS will auto adjust output efficiency stablization upto near 90% output.

你意思係 " 黃 " 駁差機既 "紅"。"黑" 就駁 "黑"
24V 就 2 條"黃" 駁落差機"紅" 。照樣 1 條 "黑" 駁返 "黑" ?
17V 就 "黃"+"紅" 落差機 "紅" ??
係唔係無論駁幾多條 "+V " 落去都整係駁一條 "黑" 就夠?

有無可以相清楚 D 呀

Yes  = 12V output

24V 就 2 條"黃" 駁落差機"紅" 。照樣 1 條 "黑" 駁返 "黑" ?
No  = 12v Output

17V 就 "黃"+"紅" 落差機 "紅" ??
= Short circuit ( no output )

係唔係無論駁幾多條 "+V " 落去都整係駁一條 "黑" 就夠?
= no, diff. +v cable joint up will short circuit ( black cable=0V = grounding )
