    Great for bench testing, or a starter solar pack, or a short-range EV. Can’t verify the exact capacity, but it still has enough umph to propel my 4300lb brick about 40miles/60km, so it’s still useful as a small pack if you have a 96v-or-lower vehicle project. These cells are about 15yrs old...

    Arrrrggg........ trying to find a reliable source of LiFePO4 is driving me nuts. Either they are ridiculously expensive, I mean $1000US per kWatt is not feasible, or its costing 10x the amount of the batteries to ship to NZ or just ask bad, duds. I am looking for something manage, 15 to 25ish AH...

    Hi, All, I’ve been watching AliExpress for 300Ah batteries… I ran across a store called “Shop 1102128819 Store” advertising new, grade A1 RoHS CE FCC UL KC 320Ah cells, 2 for $40.21. “The delivery by” date is long, at December 25. Free shipping. Apparently a store called Naiyowa-901 has them...

    I was recently given three Renogy SMART LiFePO4 12v 100Ah batteries that would no longer take a charge. After opening them up, I found moisture inside and corrosion on the BMS boards. The batteries were in a portable light tower and I assume we're exposed to rain. Upon testing I determined...

    Hi all. I have looked for similar questions here and have come up empty. I have been learning as much as I can about ev conversions to prep for my 1985 vw westfalia conversion. I am wanting to maximize range as I am fine with this slow beast staying so. I have been looking at the hyper 9 or warp...

    I'm in the midst of a EV boat conversion. Getting ready to order batteries and BMS. The batteries will be Lifepo4, 2P30S, 96 volt, 280ah each, 50+ kwh total. I'm thinking the BMS should be separated one per series group. i.e. one 30s BMS on each side. If one BMS trips out (low cell or something)...

    My truck went down in 2012 and has been sitting since. I drove over a year with the 200ah Calb lifepo4 batteries and decided to replace the manual tx with a 700R4 automatic and put in a larger motor. Just wondering what’s in store when I go to fire it up again. Lots of rewiring and have to...

    I need 8-10 3.2v cells to get my pack back up to the design voltage. I have 160AH Voltronix, about 5 years old. Looking for something in the that range of useful life to get my voltage back up to 144 after losing some to various issues. CALB or any brand is fine if they still have some life left.

    Hey everyone! I am currently working on a conversion and spotted these packs for sale on eBay. Now I know the dollar per kilowatt isn't that great on these, but I am trying to keep the costs low, so I plan to start out with a few of these for a proof of concept and then upgrade down the road...

    Has anyone had experience with LiFePO4 cells from "Shenzhen KM Technology Co Ltd"? I am looking at the KM-LFP34412-80AH model in particular. As the model says, it is 80Ah at 3.2 volts. The size is (prismatic) Height: 221mm, Length:137mm and Width:31mm I will be fitting two of these in parallel...

    As above, new or used, would also take the old 38120P or 8S of the S types (any format) or even LifeBatt X-1P.

    It's been a while since the first LiFePo4 batteries have been installed on the EVs, and now, after a few years, I think it's time to draw some conclusions about the experience with different manufacturers: performance, cycle life, any kind of problems ... So far I have noticed that many prefer...

    I have a large excess of brand new Lifepo4 cells in stock (in the United States) and ready to ship. They are priced to sell quickly, so if you are in the need for some cells or have an upcoming EV project this is definitely a steal. Here is what I got: Voltronix 180Ah Cells Voltronix 260Ah...
