I really enjoy Will's education and leadership in the DIY solar and battery community. I have a small off-grid solar system (800w) powering my amateur radio shack, but before finding Will's YouTube channel, I didn't realize how mismatched and inadequate my 12v Pb-acid AGM 200AH battery bank...

They are Gator cases - the 4U, 19" deep molded version (G-PRO-4U-19) - I found a really good deal on Amazon for them. I selected this case as a battery holder because 1) I wanted something "portable" that I could move with by hand (or with a hand truck) if I needed the power somewhere other...

Next update in the journey! I used the repackr site to group my 960 A123 26650 LiFePO4 cells (32ea 3.2v 65AH matched packs of 30 cells) to make 2ea 48v 65AH batteries - paralleled together to make 6.24 kWH of 2nd life LiFePO4 powerbank goodness! Working now on cutting the 32ea 17.25" copper...

Yes, Signature Solar sells EG4 Brightmount splice/extension kits separately https://signaturesolar.com/13-75-in-splice-connector-bonding-jumper-kit/ https://signaturesolar.com/brightmount-extension-rail-kit/ And EG4 does not sell individual components (or anything) directly to the consumer. I...

another update - I just ordered 12 ea SunPower 250W mono panels and an Outback FLEXMax60 MPPT charge controller to replace my 12V 800w array with a 48v 3000w array :) looking forward to getting that setup to pair up with my 6.6kWH LiFePO4 power bank - I ended up getting the (used) panels...

I am using a hybrid approach - I am soldering a copper bar to a 2p nickel strip and spot welding that assembly to my 15x2 cell packs to make the 30p groups. I will series connect 8 of 30p groups with copper bus bars on each pack using bolts and short lengths of copper bar and use a 4ga length...

one minor edit - since I will need 64 copper bus bars (not 32 - darn maths), I had to order more copper 110 bar stock. For each battery's main positive and main negative, I opted to use 1/8" by 3/4" copper bar (vice 1/8" x 3/8") to give my main battery terminals more "meat" to which to connect...

lol - you will have to ask those YouTubers from whom I borrowed it...

here are the links to the nickel strip that I found matches the particular 26650 cell holders I bought https://www.aliexpress.com/item/33026815694.html (nickel strip) https://www.aliexpress.com/item/1316346683.html?spm=a2g0s.9042311.0.0.27424c4dxpdxwS (26650 cell holders) shipping times from...
