  • Post in thread: Going off-grid in the North

    Thanks for thinking of me but I don't do video's nor do I put my face out anywhere on the Web. I have written up everything from land purchase and clearing to building everything out to a point. I stopped posting it as some "stoopid" started to happen and I just wasn't going to deal with that...
  • Post in thread: Who is still building DIY batteries

    Due Diligence = Learning the most you can about a subject / tech prior to diving in. It's typically a 6-month (the real keen learners) to 12-month learning curve. Sorry No Instant Rice Society solution.

    Agreed BUT Politics = Toxic Hazard to be avoided in friendly social environments like here. Universal Agreement pretty much by everyone, everywhere. All Politicians are the Lowest Form of life on this planet regardless of their parties, flag colours or other things... They're all scum ! They...

  • Post in thread: Building a 24 V battery bank: Using 12V batteries is much cheaper, but is it worth it over using 24V batteries?

    The JKbms with 2A Active Balancing is fine for the 280's, my packs all use those BMS'. The B cells are Voltage & IR Matched and still quite reasonable at that price point. They are fine if you build a straight 8S Battery Pack with it's own BMS. I have A Cells, B Cells, Used EV Cells in my bank...

  • Post in thread: Ordered 8x272ah Lishen Cells from Amy at Shenzhen Luyuan

    A tidbit of Trivia. At the end of 2019/early 2020 no vendor put a name card or showed the tests to clients. I and another member suggested to Amy (who was @ Xuba at the time) to do this and to put a Name Card with people's orders so they knew it was theirs and a fresh photo, not just a recycled...

  • Post in thread: Xuba Electronics: DEAL - 280AH LiFePo4 cells. Purchase & Review

    TECHNICAL UPDATE The "Bumps" people have mentioned. I just got these two photo's (combined them to two) from Amy @ Xuba, she peeled the top off to show what is causing these bumps people have reported. NO DEFECT ! It's a manufacturing plug. This is reassuring and I believe people should not...
  • Post in thread: Just Place new Order on Alibaba- 280AH x 8 for 1260.00 USD Delivered, Grade A to Canada

    Hehehe... well I have had almost daily chats with Amy for months and it's not just battery cell talk... She is Happily Married with daughter so it's NOTHING like what some might think. I've facilitated introductions between XUBA and Chargery BMS' Company an others as well, they now offer...
  • Post in thread: 24v Bank Dead - upgrade to 24v LiFe or scrap system for 48v - WANTED recommendations

    Yes but you have to understand that I designed & built my home and did so with Efficiency in mind because right from the start (even before buying my land) I knew I was going offgrid solar powered with this build... It's my final build and my Bucket List item I wanted to do and I had a lot of...
  • Post in thread: Documenting Purchase from Amy Wan of Shenzhen Luyuan Technology Co. LTD. Alibaba

    Ironically, had he setup an arrangement with Amy @ Luyuan and he could have arranged bulk buys & deliveries... Volume = lower sale price. Even if a bit higher for the Matched Cells the bulk cell options are there too. It is ironic, considering some have bought volume and got great pricing, but...

  • Post in thread: Almost everyone is charging their LFP wrong!

    A missed Connected Dots. LFP Nominal cells voltage = 3.200V which is 50% SOC per manufacturer specs for the chemistry. The tested & validated working voltage range is from 3.000 to 3.400 , it's a simple fact of the chemistry, regardless. LFP will always settle post charge regardless, it IS the...

  • Post in thread: Cell prices coming down

    A point to NOTE: Alibaba is NOT AliExpress and many vendors do business on BOTH sites. Each has its Pros & Cons when it comes to dealing with vendors <-> Customers and their resolution processes. Each are essentially both Chinese Amazons as such. You can also buy the same Batteries & Cells...
  • Post in thread: Samlex: Dual AC and Solar Controller inputs, BMS Controllable, Fully programmable

    Hello everyone, I am a recent member to this Forum and have noticed very little knowledge about a certain product line of Inverter/Chargers, namely Samlex who has been in the business quite a long time.

    There are NO STUPID QUESTIONS EXCEPT FOR THE ONES NOT ASKED ! Below are A-Typical" installations. Each battery pack is Fused. You can use MRBF (up to 36V) , Class-T or Mega-Fuses. for 12V, MRBF is very suitable. Each should be fused for Max Output amps which is likely 50A for each battery...

    Dumped the 3500 Square Foot CapeCod styled house. Got rid of the 64 Chevelle SS, 69 Beaumont SD-396, the Dodge Ram and all that "Junk" and downsized to a Ranger 4x4 & inherited a Military K15 4x4 for the Really Nasty Days. Bought unmolested rural land, South Facing, Top of a 1700' Ridge where...

  • Post in thread: Utility rate increases

    Eye openers for anyone interested. https://www.electricrate.com/data-center/electricity-prices-by-country/ kWh rates are only one part... A LOT places have delivery fees, assorted surcharges & levies and of course taxes added on top. Now that is a real stew of "stuff" that varies everywhere...
  • Post in thread: Utility rate increases

    A New Build can be optimized for solar and there are now several companies making Solar Shingles as an option. Roof Angles etc can also be better optimized and designed to accommodate solar... think skylights, vent pipes etc which can all be a huge PITA if in bad spots. East-West roofs can...

    I apply the Rule of Three as a sanity/safety check. 3 Attempts and that's it. There is no 4th. If Lied to or Info Misrepresented it's an Automatic 3 and they're out. Humans use this all the time qithout realizing it... It can save one a LOT of headache & stress and can be applied to almost...

    To properly Match & Batch cells (of any kind): Simple breakdown each cell must be mounted into a testing machine, each cell has to be fully charged to 100% and IR tested. Each cell is discharged at Varying Rates and at specified setpoints, IR evaluated & recorded @ that Volt Setpoint. Each...

  • Post in thread: Just Place new Order on Alibaba- 280AH x 8 for 1260.00 USD Delivered, Grade A to Canada

    There IS a trick to this … a ZEKRET for shopping on Ali* DHGate & others.... Often a company will list the price of "single" units at one rate, then in "bundles" with a slight discount per "item" depending on the size of the bundle, 4, 8,16 cells, in this case. So you must pay attention to...
