    Creating a spare pack

    I have 1 spare sitting at 3.8V that i can easily get charged or Discharged similar to the rest of a string to swap out for errors. I also like to have more strings (packs of 7 cells in series) and have the ability to take down a Pack without loosing power totally

    Expanding Li battery (Nissan Leaf)

    The Other thing you can do is pre test each Cell (pair of cells) for capacity and Build your next battery with balance in mind from the get go. Match each cell as best as possible and then you will need little balancing.

    Kinda Similar to deicing fluid on planes. Even like a car windshield sprayer just enough to help start the melting.

    What are some practical techniques for sorting cells in bulk quickly?

    the Capacity tests are my active packs capacity. For these packs in service they are held to 4.05V to 3.6V per cell but for the most part their cycle depth is really shallow. The cells tested were sitting for 6 months held a set voltage of 3.8V set by a digital voltage PS that I have...

    What are some practical techniques for sorting cells in bulk quickly?

    100% Agree Wolf. I have batteries that I have tested good Let sit a Month and are still good. After sitting for 6 months some are showing some self discharge. I realize that is kinda going overboard but all my built packs using the above method are still 97% the same capacity 2 years...

    I think I found the issue... HEATERS!

    Huh that is kinda opposite of I would have thought. I was thinking that lower capacity packs would bypass more since they would reach higher voltage sooner it would start to bypass. but yes after changing packs one would need to backup the data then reset it to get an Idea of the Health...

    i think i found my perfect solution

    Why 9 Inverters? 45KW??? that's an insane amount of Current.

    lightweight electric lawn mower

    Here in canada we have the Mastercraft Brand from Canadian Tire and I have their 40V 19" wide cut lithium powered lawnmower. It's nice and light and collapses down to a small size. was $299 CAD and is a very nice lawnmower. brushless design that will speed up if it encounters thick grass and I...

    Holding the cells together in trays

    I drill holes in the black area's of the Holders and over the Bus bars. (Bus bars are 3 strands of 14awg copper) then that holds the pack together

    MPP Solar LV6548 Inverter

    Ouch Yea I'm looking at staying single phase. That an it will be an easy transition to 48V as I have my batteries setup in matches 14s sets (Currently in 7s Config) The Other thing I did see was integration with a BMS but they looked to be tied to specific Battery system manufacturers...

    MPP Solar LV6548 Inverter

    So I've been looking to upgrade my home Inverter lv2424-hs to a MPPT model and higher Wattage and came across this Beauty LV6548 Looks to be a nice upgrade (3x the Wattage) and up to 8000W of solar input Pricing I have found looks to be in the $1000 + USD which for me will be closer to...

    Charge two 14s 18650 packs together?

    Just when connecting the 2 packs together check and verify they are at the same potential. I use a 1W 10 Ohm resistor to slow the current for any batteries that are not the same just to eliminate the big Amp draw and Spark associated, But i have not had problems doing this. I do connect...

    MPP Solar vs Victron

    When I was looking at my setup where I have solar but also want grid charging and the ability to switch from grid to battery with no loss of power I looked at a couple different Hybrid units. None of them has it all so I was looking at 2 units anyways but with the MPP solar 2424LV I get...

    Dala's Leaf buildthread (2015 Nissan Leaf)

    Wow That's a nice rate. Not sure what the coneversion to Canadian would be but we are currently paying 10.1c /Kwh due to Covid but normally we were paying Peak @ 20.8c /kWh Mid Peak @ 14.4c/kWh and Off Peak @ 10.1 c/kWh. We will see what they do on the pricing when this is all over
