    Yet another Yellow Ninja 250 Conversion!

    I have 4500 miles on the Ninja so far....took the CALB batteries out last weekend. They are still going strong with no noticeable loss in power. I put them in a 4 cell configuration for 12v and ran a 300 watt load. Got 40 AH down to 2.8 volts per cell! I pulled them as I just bought 11 Leaf...

    BMS Battery Alloy Shell Charger Problems

    I have the 600 watt 84 volt version. I was running 24s but recently added a cell. Was pleasantly surprised that with just a 1/2 turn on the Voltage pot I got 88 volts and a full charge with 25 cells. I'd add another cell except Im now at the top limit of the Kelly Controller. After a full...

    Inside view of a sliced TS 90Ah battery

    Can a post mortum be done to determine why it failed? When these cells fail due to over discharging what fails/happens??

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

    Thats the part most disapointing to me...they stated them as new when they CLEARLY are not. They said the single cells were new, and they are. I was going to order a 7S3P pack...now I definately won't. If they said as is then fine...but instead they chose to lie.

    A123 20AHr Pouch Cell Battery Build & Info Thread

    I looked at this last night, was thinking of keeping the tabs flat against each other and using two cotter pins, facing opposite directions...then solder a balance lead and 2" shrink wrap to finish. Pretty simple and effective!

    Me too, no problem...56 cells $18 each, got them 5 days after paying. Smooth as silk. It appears buying cells goes smooth...modules have had problems, buying, packing, quality. These sellers are just traders....when the supply goes away they will sell rubber dog shit if they get it at a good...

    Not at all! Mavi's spec is "Nominal Capacity: 18.5Ah min, 19.6ah nom" down to 2v right from their website and plot....All that graph proves is that they just sent you the VERY best plot they had!...actually above their spec @19.7 Doc's cells and mine all vary by about 1 ah. Look at Docs cell...

    No one knows for sure....the cells that have been bought are definately new and meet the same spec as that posted by Mavzin...offical A123 supplier. As for the packs, they are worth the gamble because they can't be BOUGHT anywhere else for ANY price. They are being sold as surplus and very...

    I see Jack R has a prebuilt 28S3P pack coming in from China. Did anyone see in his video he had a nice little clamp with a terminal post? Would make it very easy to assemble P packs.

    No need to get an "unbiased, cough" graph from Mavizan....right from their own website they spec 18.5 - 19.6ah @2.0v lvc nominal capacity at 1C right? I have over 80 plots of my own that meet this! Does this mean I have grade "A" ? maybe, but I DO have same as Mavizan. I also have dozens of...

    No YOU say it covers all grades, sorry, but you just have no idea. FACT: The A123 from Victpower meet SAME spec as posted by Mavizan, as YOU call grade A. A123 uses 2.0 as their LVC ....useable in real world? hell no. But its what they do.
