    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    Wanted an A123 (28s3p) Battery Module. I originally purchased three from China which arrived with varying issues. One of the packs came with a shorted cell and smashed in corner that obviously had happened prior to shipment. I was able to bypass the damaged cell because it was on the end and...

    Given your modules look square and nice. Did yours come with wood feet added in middle and a thicker bottom board as I suggested to Xin they needed to do? If yes, I am glad someone benefited from my input. Attached pictures shows the fine care and quality of packaging Victpower used on my...

    Based on prior experience on a Prius pack, Paypal will require you to send back the modules. If you are willing to send back on slow boat at a lower cost, and wait to get additional module or through other methods as was just suggested, I would NOT drop dispute and continue to keep Paypal on to...

    If I can’t get the Mini to run reasonably well on two packs for trips to work (if other two packs are any good), I will likely try to salvage the bad pack if enough cells take and hold any charge. All the cells except the shorted one were down around 0.6 volts Right now I can only attempt to...

    Sorry you are correct nothing new. I was so worked up over their final offer last night, I had forgotten they changed the terms from when I ordered. In my case Xin wrote me before the sale that they would replace defective module if bad. When I said I wanted to return the bad module for...

    As we understand now, Victpower knowingly shipped obviously defective modules and appear to be using the high return shipping cost as their protection. Before you buy a module, you should also understand, they require you to return the defective module at your cost, and also require you to pay...

    Did you mean to say or was there a typo: "To charge to 100% you should charge at 3.65v at a constant current until cell or module voltage is 3.65 then decrease current holding voltage at 3.65 ..." I am not sure your required or would want to try to drive current to a level to force the 3.65 v...

    Oatnet, Thanks !! That’s what I hoped; a very flat curve compared to what I am use to. Now I can continue with yours and Miro13car’s input with less concern. I have experience charging our 300v 84 module Prius NiMH 13 AH pack we assembled at 4 amps. Since the 4 amps is a much higher...

    Been charging the module that came at 77.4 volts using a fixed 120 V power source and old power slide resistor. Charging at 2 amps which is max of the four 30 volt vicor modules I am using in series. Module voltage came up as one would expect. Put in about 20 AH and now all the cell voltage...

    The module were delivered to US Indiana. From pickup in China to my driveway in 3 days , amazingly fast. There were no added costs or hassle, the payment transaction and delivery arrangements went exceptional well. The main issue with the shipping packaging IMO is need for additional wood...

    Received our three 28s3p packs today. Two modules are significantly out of square. It seems this is due to the shipping packaging or improper handling. All three modules are used and have heatsink compound on their bottom. One of the significantly out of square modules has one corner of...

    HumboldtRC, I ordered three of the 28s3p packs last week to replace the small Prius battery pack in our Mini-EV project. Curious to know if the material connecting the cell tabs is all the same? I was speculating that for the Al cell tabs they were using Al, and for Cu Tabs it was Cu. I...
