    Lipo Load Bank for Discarging

    ***Sale Pending***
    Guys,

    I built an extra load bank I use for cycling cells and am offering the extra one for sale. The load bank has two 600W planar resistors that can be wired in series for higher cell count packs or in parallel for lower cell count packs. In series configuration for 8S/10S/12S the load bank pulls around 24A@42VDC. In parallel configuration for 3S/4S/5S/6S it pulls around 42A@22VDC. For the 3S/4S/5S/6s packs you could just use a single resistor for 21A. The heat sink is black anodized extruded aluminum approximately 10" x 6" x 2.5". There are four 24VDC Pabst ebm fans to cool the heat sink which flow enough air to keep temps reasonable. The fans are wired for 24V and are connected in pairs to each resistor. Hence when the load is applied in parallel wiring each fan sees the input voltage. When the load is connected in series wiring, each resistor and pair of fans see half the input voltage.

    You can use these as a stand alone load bank or this can be connected to certain chargers like the iCharger 4010 which can accept a resistor load bank. If you do decide to use this as a stand alone system always use a battery checker or cell monitor to check on voltages. And needless to say do not leave a battery discharging unattended.

    Asking $220 shipped CONUS. I will ship international at the buyer expensive. Any questions, post here.

    The pics show the same unit connected in series and parallel.

    Tyler, would you be offended if I offer $200 shipped to 91006? I would love to have a shot at this.

      Since you are in CA, how about $205 shipped.

        Tyler thank you so much for your generosity, may I have your PP info?
        Also I am at work and won't be able to pay until this afternoon.

                    Did I miss anything???
                    I don't think that is money he is offering, that is Brian's SAW pass speed!

                    I know we are not supposed to bump the thread, in case people are wondering, let me just say that it is well worth the price of admission. I already bought a power supply from Tyler as well as a junction box.
                    I have been looking for a meaningful Lipo discharger for awhile and I was just lucky to be the first one to catch this F/S thread last night.

                      Tim,

                      Just a little humor from Brian on his anticipated speed. We are tenths of a mile an hour apart on maximum speed and both just under the record.

                      And just for you Brian;

                        Tyler,
                        item arrived safe and sound.
                        As usual, this is wonderfully built and I look forward to using it for many years to come. The photos do not do justice to how robust this is constructed and the heat sink is a beauty! Wow...
                        Thanks for the deal!


                        BTW, I knew what Brian's offer was, good luck to both of you in your quests!
