    We use Ford C-Max (Energi) 7.6 Kwh per battery and we pay less then $75 per kilowatt and they are Panasonic made in Japan cells. Been using them since 2018 with no BMS and they run our home 24/7 and yes, I have checked the cell voltage a few times and they have stayed where they were when I purchased them so take it or leave it.

    I've built two EEL cases and both times dropped a screw in the back, which fell through the slots. Try using the foam cutouts (scrap, for the battery vents) to block the slots in there before you install the balance lead bars with the screws in the back

    • @johnhufnagel
      @johnhufnagel 4 месяца назад +2

      ok rather than delete/amend, i'll reply to my own post, since I didn't do enough diligence.
      So looking up the total cost of an EG4 LL-S delivered to me, it'd be ~$1700.
      the complete kit ((China stocks) 15KWH DIY Battery : 48V DIY 280/304 kits + 16pcs EVE LF280K V3 cells + Inverter cables + RS485 connector) would run me ~$2000 delivered.
      So for an extra $300, it's nearly triple the capacity. It's a lot of scratch to lay out at once, but it's also a lot of capacity.

By comparison the CHEAPEST Price on the EG4 PowerPro Indoor Model battery is $3,299 BEFORE Taxes, with Tax (for me anyway) it jumps to $3,529.93 so I saved like $1,345 by assembling the battery myself.

    Good job & nice build, looks like a solid unit, I did notice it is missing the Confirm (yellow) button, or is that how it is meant to be? Would be nice to know more details of the BMS used, type, surge capacity, balancer type & current, etc…
    I would double check ur sequence for installing the balance leads & battery main leads, as I thought ur supposed to tighten down ur battery leads before plugging in ur balance leads because if ur 1st & last balance wires are mot making a good contact when you plug in the leads it can give a BMS error msg, but it may not be the case with this BMS.
    What an excellent build this is, been checking out ur other vids, good info. Cheers

    @candro5510 Год назад +1

    Good job. I am on my way to build myself one. I bough the DIY box kit from Cassie Zhang (I'm from Europe). Next month I will buy the cells. From what I saw, eye-shopping around, this kit looked ok. Yes, for a 15kWh battery, the price is around 2/3, and you learn something in the process. I have 22kWh installed already (from ready made batteries) and according to what I know now, for the price I should have 32kWh. I do believe that DIY is the way to go as the readily made batteries become more expensive instead going the other way due to the increased number of manufacturers. Anyway, here in Europe, the energy is quite expensive and being self reliant on it is a must (due to prices and the less maintained grid). Let's not forget the natural disasters that could become more frequent due to the already well felt global warming.
    Having more EV's is putting a strain on the grid. I suppose that on the long term, if nothing happens (like WWIII), the batteries prices should go down.

I ended up having to pay $127 for them to ship out 3 replacement batteries. I think Jenny Wu should have covered the cost completely. I also think having to wait a month is pretty shameful. BUT I guess it could have gone worse. Well, it did get a little worse.....
      I also had a problem with one of the Apexium boxes. One of the temp probes was not soldiered on to the balance PCB correctly. This took me a couple hours to figure out and kept my battery offline for a day..... It was actually just glue that was holding it to the PCB and keeping the temp probe leads in contact. I let Jenny know about that and took pictures to make sure their manufacturer does a little better quality control. They are sending me a new board.
