I am considering a P-Squared Phantom 2/3 Quadcharger GO ( P-Squared Phantom 2/3 Quadcharger GO ) which is priced at ~ $80. There is also a P-Squared Phantom 3 Quadcharger Pro Package that includes a 27V 20A Power Supply ( P-Squared Phantom 3 Quadcharger Pro Package ) which is priced at $369. So the Power Supply cost is $289. While not impossible, it is difficult to find and costly to purchase a 27V 20A Power Supply, however 24V 20A Power Supplies can be obtained at reasonable costs and are readily available. The OEM Phantom 3 Chargers have an output voltage of 17.5V at either 57W or 100W (A versus P). A fully charged P3 Battery Voltage is 17.4V, and the "charge controller" is contained within the Battery. My thoughts are to purchase the Quadcharger GO without the Power Supply, and obtain a 24V 20A Power Supply for the voltage source. My question is: Is a 24V (as opposed to the 26.3V or 27V) source adequate to fully charge the P3 Batteries? Any input/comments appreciated. RodeoGeorge NOTE: The TP-1527PS Power Supply (27V 20A) can be obtained for $150 as opposed to the $289 listed above in the Combo Deal.
