That goes for Amazon sellers as well.

Looks like a different cell than mine. Yours has a larger stud and mine has an M4 hole in the top. Why don't they just sell them as what they are. My Amazon seller said the code was not relavant that capacity was what mattered and they failed there as well. I got 92Ah from mine. Made in March of...

Thanks for the confirmation on that. Buyer beware. What did you end up paying per cell after all was said and done? Mine were not cheap since I paid Amazon prices. I will probably return them. I just tested mine and got 92Ah at a .3C rate.

Here is the link to what I bought https://www.amazon.com/gp/product/B09TDKWBT7/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1 The question is did I get what I paid for or is this a bait and switch. I will do a capacity test soon and let you know what I find. Ok so I made my first battery...

The vnsznr guy said that they come from the same factory so Daly is just another distributor of the same stuff.

So is vnsznr just a US distributor for Daly? There must be a connection.

Is the REC contactor based or MOSFET based?

So what is the exact problem. It looks like it cut the charge because of one cell going high. Is that not what it supposed to do?

This is why I don't want something that is gray market from China. You have to hack it to get it working since there are no instructions in English and very poor documentation. You also have to wait a long time for it to ship.

I would connect the load (a motor) to the battery. The BMS would be connected separately from the motor. This would give the BMS control over charge and balance and no control over load. This would be stage one for me to use a cheaper BMS to manage charge and manually monitor cell health with...

I would only use a contactor for the load side on a high current application like an EV. The BMS can handle charge cutoff since that will be below load currents in most cases.

Where do you get a JK BMS?

I am leaning towards them. I did some research last night.

Ok was being somewhat sarcastic. It seems that most of these cheaper BMS units have little or no documentation and what little they do have is in Chinglish. I don't want to buy half a dozen of these things to find out most don't work as advertised. My application is solar and Electric Vehicle...

Another way of totalizing is a coulomb meter. Most battery manufactures have a voltage chart showing the state of charge as a function of voltage so that is a rough guide. You can discharge your batteries down to their limit and measure what is left. If you measured capacity when you put the...
