So simple, he assumes we already know how to do it?? I'm looking for something just like this, but zero luck so far!
maybe you could run a relay with the power running that beeper, and run a contacts cutoff switch. the cheep Ebay battery monitors have a relay for 20 amps .the higher amp ones you ad your own relay /contact switch. some may have temp cutoff too. mine with no temp, was like 3 bucks afew years ago. and it has Bluetooth.
Put some ~1.5" diameter holes around the bottom of the pipe with the power resistor in it. Set it up on-end with the holes on the bottom, and when the resistor warms up it will draw cooler air in from the bottom to make up for the warmed air exiting the top thereby keeping the resistor cooler. AKA, the chimney effect.
So is there somewhere that shows how to build this unit?
I have a powerlab like yours what settings would you use to discharge your homemade battery. Any help would be great. Thanks
Should we bottom balance while making the packs? I mean each cell?
300 ah at 3.9 volt, would need 38 more of those for an ev. Would take a lot of space. What exactly did you build that one for?
is all the pack for power wall solar are made in 3.7 v all the cells in paralell and connected in series
Lol marketing that good
Can you balance a pack that is in parallel and in series(18650 pack making 11.1v)? Or you can only bottom balance batteries that are in parallel?
This 2.7V is the cut-off voltage of the cell(specs).
Maybe add a fan to help dissipate all that heat
Iv been thinking about the balance issue. For a smaller pack it should be possible to build the battery with "some" switches so that you could easy disconnect the cells from both paralell and series. Then using individual chargers for ea battery set to the prefered volt. Doing this every time you charge = balance and never have to top charge or bottom.
Also using A bms for protection during use.
Good concept or stupid?
can you make a video on how to make this thanks
Also, my battery manufacturer recommends connecting all the single batteries in parallel before putting however many in series for 24 hours, I imagine this makes them balance their charge, they are all at around 3.2, what type of balancing is this? Is it really useful in any way? Gracias!
Thanks for the info! For what I heard on another of your videos, I should probably use my new batteries for 100 miles or so to discharge them some, then do the bottom balancing slowly and carefully… I'll have 144 batteries in a 24s6p pack, it's OK to just do the bottom balancing on the 24s not the whole 144, right? Thanks!
I dont understand why every video i watch, after completely draining the battery everyone charge to 3.5V per cell? Why 3.5 always?
