    Tim is in da house with a powerwall

    Same here :P !!!! Still in the 'testing phase' of my cells. Due date for my project is next spring. By then I should have about 10kWh which makes it interesting to start of with. That means I would be able to run nearly everything of the powerwall during 'sunny months'. Only thing I still need...

    Start of a new powerwall in Belgium

    They were actual Panasonic battery packs. Out of the 43 packs I salvaged, unfortunately I only found 2 :(

    Start of a new powerwall in Belgium

    Full time testing and still dismantling (Have about another 20 ebike packs laying around ready to crack open). As soon as I have 1120 cells fully tested, I will start assembling the packs. Still on track for starting up in spring 2019. In the mean time the inverter has already...

    Greetings from Antwerp (Belgium)

    Tony, But if everyone is saying that... there will never BE a solution ;) Everybody needs to take a look in the mirror sometimes and think about what he or she can do to start making a change. It all starts with small (baby)steps. Anyway... WELCOME and enjoy !! Any project you're working on...

    Import & Custom?s per country

    @Franky, Didn't you know they have been saying this the previous 2yrs as well ? Don't panic, there will be power. Don't you think it's strange they come with that news just before local and government elections? All propaganda to try and influence people. Relax.

    My first harvest!

    I have a DIY spotwelder. Used the kit you can buy from Malectrics. You just need to buy a decent car battery and you're all set. I'm loving it. I already 'refitted' 3 original ebike battery packs with it. Now I'm testing all my cells to make my powerwall packs and then I'll try the DIY...

    Batterypack for speakersystem!

    Grymer, it sounds like you can use the Headway 38120 cells instead. Google it, like you have this community here that mainly specialises in powerwalls, there's also a community that's into audio. Mostly for car audio but since you want to work with battery it's the same. The Headways are even...

    Start of a new powerwall in Belgium

    So after reading tons of stories and watching hours of YT clips I've finally started off with the basics... 'salvaging cells' !! In the beginning there was nothing... After some searching I've finally found some sources. All of them are ebike battery packs (Bosch, Giant, Panasonic, etc...). So...

    Cell Counter

    ok... got you now. Starting official project now then. :D

    Cell Counter

    That's what I meant. Idiot me.... I never saw that line up top where you could just adjust . Thx Korishan for pointing out. Hmmm.... I can't select my project in the drop down menu !?

    Cell Counter

    Hi guys, Is there a way to update my cell count? I had 50 but I'm disassembling a BUNCH of ebike packs and the count is rising VERY FAST :P At the moment I'm already up to 360 something and still got about 18 packs to go !! Thx. Yoeri

    Sold to the Powerwall idea !!

    Woeha.... finally a big boost for the project. I was having trouble finding 18650 cells. Today... I had to pick up my moms electric bike with my minivan and bring it to the repair shop (problem with motor). I rolled in the bike, told him what the problem was and then I just asked him: "You...

    Does a BMS have some kind of memory(effect) ?

    Ok thanks. Were brand new batteries so they came in at nom voltage.

    Does a BMS have some kind of memory(effect) ?

    Hi, So here it goes, I've exchanged the old cells from my moms e-bike battery for newer better capacity cells (The green Panasonic ones :D ). I carefully dismantled the battery (Giant Twist) so I could re-use everything. All went pretty fine, installed that BMS again... everyting connected...

    Hello from Cheshunt, UK

    Hi, Join the club ?. ... and if youre a coder, theres enough help needed/wanted coding communication between different inverters and an RPi 3 for example. So a warm welcome.

    The finish-ish of a pcb based 14S 80P powerwall

    Looks really nice and interesting cause I don't like the soldering on cells. Most likely due to my handling, I'm quite handy but soldering 18650's doesn't really go well for now. Have you already been able to test out a full pack ? How is the heat dissipation at the terminals from the cell...

    Sold to the Powerwall idea !!

    As I'm calculating the necessary starting budget for my system, I came to the next question : "Would 7 panels of 300Wp each be sufficient enough to charge a 6kWh battery pack with a days yield?". Are following calculations plausible ? 2100Wp * 0.8 (correction for winddirection) * 0.8 (losses in...

    Sold to the Powerwall idea !!

    Oooh.... OK, sorry to be the 'pain in the arse' but I think I got it now. I thought when it pulls 20amps it would be divided over the complete string of 14 packs but it doesn't, in fact, it pulls the 20A from all packs. So if I calculate current I only look at the cells in parallel. Idiot me...
