I have two RSP-2000-48 units in good condition for sale. I bought them about 4 months ago and have used them 2-3 times to charge my 96V R6 conversion (28s). We were on the bike for about a two weeks and I realized that with my current riding I just have no need for fast charging. I have only done two mods on them. Drill a small hole in the top of one unit so you can get to the one pot that allows you to adjust output current (like 80-100%). I have also added white silicone to the inside of the units on the inductors, the larger capacitors, and the vertical boards to help make the unit handle vibrations better
I will sell them as a package with the diodes installed as is for $625 shipped. PM me with any questions or offers.
Thanks
Kyle
