Yes I do have the PS4 charger. But, I don't think it is putting out anywhere near 15 amps per battery using the Honda 2000. It might do better when hooked into a 30 amp dock circuit. I know the Zivan is providing 16 amps because I can read it on the XBM. I need to run down the bank then use a clamp on DC current meter to check the how much current the Dual Pro PS4 is actually providing each battery when charging via the Honda. Unless someone has already done this? If it was providing 15 amps per battery I would think it should be charging the bank faster than the Zivan. But, I don't feel this is the case.

Hi Mike . i thought you have a PS4 . On their website Dual pro rate this at 15 amps each output . It maybe that motoring at 15 amps puts a higher strain on the charger than just 15A charging batteries. Wheras the zivan has a higher rating so is not so affected.
+++++++++++++++++++++++++++==+++++++++++++++++++++++++++++++
PS1 One 15-Amp Bank 15 Amps 5.00"H x 8.25"W x 6.38"L 7.00 lbs. 12V
PS2 Two 15-Amp Banks 30 Amps 6.00"H x 8.25"W x 9.50"L 14.50 lbs. 12V, 24V
PS3 Three 15-Amp Banks 45 Amps 6.00"H x 8.25"W x 13.00"L 22.50 lbs. 12V - 36V
PS4 Four 15-Amp Banks 60 Amps 7.25"H x 8.25"W x 15.78"L 29.80 lbs. 12V - 48V

> Be careful about confusing Ac amps into the charger input vs DC Amps on the output. This is an issue I've been wondering about. I have a feeling the Dual Pro does not charge the bank as fast as the zivan. If the Dual Pro is pulling 10 AC amps from the Honda I am assuming all four batteries in the 48 volt bank are discharged about the same amount . This should be divided evenly between the four individual charges meaning each individual charger is getting 2.5 AC amps. I have not seen a circuit diagram of the Dual pro but, judging from it's weight it seems it has some pretty hefty step down transformers inside. Which will lower the AC voltage but, increase the current on the output of the transformers. I know my Zivan is providing 16 amps DC into the battery bank as measured on my XBM battery monitor. I just don't think the Dual Pro is providing all that much current into each battery and so seems to take much longer charging using the Honda. But, I have not as yet measured it. I don't think each charger in the Dual Pro would be capable of providing the 15 Amps dc you require for cruising. If it were to be used as a power supply for motoring. I welcome other comments on this from those who may know more about the Dual Pro and it's circuitry.
