    I'm still trying to decide if I'm gonna go the 18650 route for building my power wall or if I'm gonna go with prismatic cells and build with LiFePO4 batteries since they're just easier to throw together and there are less individual cells to deal with. Your boards do make the decision harder though. Either way, I am going to have to deal with having a pretty serious cabinet in my house full of batteries though, as I want to get somewhere between 21-28KW of available power. My intent is to divide up the power output, through buss bars, to several inverters and to run different things like an instant hot water heater and mini-split air conditioner.

    Jehu, First Thanks for all the information. Second Can you break us off some knowledge on Supercapacitors? Whats up with those? Are they everything we are being led to believe on some YTChannels ?

    Watched all of first video to find it was a failed project without linking to a successful project. This video also is about an unfinished untested project. Just a dream so far.

    Jehu as you take down the old systems please photo them to document for the JeHu wing at the smithsonian. LOL

    Would these be a good way to run a 24V scooter? I would solder the cells.

    just an idea:: why not design a smart BMS (canbus) on the PCB?

    Hi Jahu.
    I guess i got the solution for your heating problem of your 18650 battery holders. I hope you have seen the heat sinks on computer processor. They are designed in a way to decapitate the heat out. To solve this in the cheepest way use the 1 inch copper tubing that is used in house hold AC. Cut them in the same size as the 18650 cells and then split them in half.
    Add heat sync compound on inside and put each half on every cell. Copper is the best metal to decapitate heat so it will keep your batteries cold enough that the heat won't get transferred to 18650 battery holder.

    I've been delaying my questions trying to figure this out but I need help to clarify my confusion. I'm going to build a 24v 18650 cell to power an electric driven reel mower. How and/or what should I use to charge this pack and how does a BMS fit into the story.

    What is your max allowable self-discharge for cells? If you charge to 4.2 and let them sit for a while how far do they drop before you call them bad cells?

    Hi! do you sell power wall sets already made?

    Where you getting your sma fuses and which kind for your v2 boards?

    I cant wait man. I want this now. Your going to be rich too btw.

    Merhabalar sizi yakından takip ediyorum fakat böylesi değerli ve mükemmel bilgileri türkçe alt yazı ekleyerek bızlerede sunabılırmısınız. Çok teşekkür ederim.
