One thing that caught my eye. He used LED Strip lights which have colour capabilities. Wouldn't it be cool if there was a way that a BMS could send a signal that changed the LED colour if there was an error or fault of some sort. White for good, yellow for warning & red for "Oh Shit something...

WOWZERS, some of the stuff posted in this thread is Gobsmacking - a Few dingalings have popped their heads up for target practice. A few comments made really help to alert WHO to completely ignore & place in the Ignore/Block list. I miss the good old days when this forum first got going...

I watched the Video, everything there is really well done and I see no issues of any sort. This is inside in a temperature controlled environment so that eliminates several possible issues. The cells are bound enough to prevent any stress on terminals from the small amount of expansion &...

I had a situation with my old ford recently and had to change out a cable and silly me, rushed down to the local UAP/NAPA and got one off the rack, I checked the crimps and just before I was about to add my own heat-shrink on the ends (they had none) I noticed the wire looked odd ! I decided to...

Spotted a GOTCHA ! You have Active Balancing running when the cells are in the middle of the Voltage Curve. Lessons Learned dept, that does not do any good and actually causes other side effect issues. Back in the day, I started with QNBBM Active Balancing, then tried the Heltecs for...

WOW ! To go through all that to provide power to the grid ? That setup could likely power your house with batteries & zilch grid usage. Now your deep into the Rabbit Warren of hooey with power co & town...

I don't think this is that nefarious. If you use grid power - the CoOp will be the sole provider and that you agree to purchase that power from them according the rates/tarrifs that apply to the company. The limit is a CAP for what that they can/will only provide for a Commercial...

For me, JK has been good & solid and the new Inverter Edition BMS' answers several needs & wants beyond the previous versions. They are flash updateable to stay current (many are not) and they are being enhanced & updated regularly. I have been using JK 150A & 200A BMS' for quite some time...

Once a Cell reaches cutoff voltage (set in BMS), the BMS will set to 0% SOC and shutoff Discharge. Depending on what is set for Power Down Voltage it may completely shutoff, this is correct behaviour for the BMS. If not powered down, it should still have Charge Enabled. Cell 12 appears to be...

OK, just to be clear. You want to use a 16S Case, but configure the cells into a 2p8s for a 24V/560AH battery pack, with a Max output of 300A. 300A Continuous or just for surge handling ? Yes, you can use a 16S Case and setup the cells in 2P8S but the Cross BusBar will have to be sorted. You...

Honestly, series connections to make 24V or even 48V is NOT the best way to go, it presents MANY complications & potentials for drastic things. It is FAR BETTER to stay Native meaning for 24V system use 24V Battery Packs. Kludging & bodging together stuff "always" complicates unnecessarily and...

I would be helpful if you could screen capture that pack when it is charging & reaching "full" and things are tripping & being logged. Pack 1, Cell 15, also has a higher resistance, might wanna check that & verify it's good & tight. Your pics do not show cells 8 & 16 but you have a couple of...

The house burning down due to a fuse failure can happen with ANY Battery Chemistry regardless of voltage as well. Quality Breakers & Fuses rated for " the purpose" they are being used for with proper & correct mounting is essential towards building a safe system. A great deal of people are...

If they are not Pure Copper they are good Orange Brass at least, Now I am checking the resistance through the terminal, which is 0.38 mOhm. Brass is extremely recycled, every recycle makes it lighter/whiter, the more orange it is the more copper within it. Pure Clean Brass is fine but recycled...

The Single Terminals are plated copper, M8 Bolt, dimensions are 35mm X 35mm, cover dimensions are 108mm X 90mm.
