Got a Battery Charger that is an Amp Hog? Well here is a solution for you!
The power supplies I have in the picture below represent the most robust and safe system I could come up with and now after building a few, I thought I'd my sell my spares.
The parts I needed to makes these work were
(1) Nylon screw and washer
(2) Pin headers to plug into the main board to turn the power supply on.
(1) Zener diode to provide a dc- case ground if we have a fault.
(2) 30A keystone binding posts. (use ring terminals for more current)
(1) Angle aluminum to make the front plate out of and fasten power supplies together.
(2) Jumpers with ring terminals to wire the power supplies in series or parallel.
(4) Internal jumper wires to go from the binding posts to the main board.
(1) Holes drilled in the angle aluminum with the jumps and binding posts installed.
(1) Heat shrink tubing.
The first two Power supplies were completed and tested (and then proudly shown off) and wound up being sold to Doug Harnish.
Now I have three sets left and figured that they could find a good home. All of these have been load tested and come with my personal GUARANTEE to work at full load. I'm asking $100.00 for each set, which is exactly what it cost me to purchase all the parts, never mind the extra for shipping. The power supplies can comfortably run the power lab 8 at full power (24V) on a 4s battery (~650 watts) while simultaniously running a cellpro 10 and cellpro 4 at max (12V).
--Oh, one other thing: They also come with a special "Y" harness power cable for plugging into the wall outlet. This is a factory made plug that is used on these type of power supplies for redundant power supplies.
