    Update. Replacement BMS? What's next?

    I am actually pretty confident that you can get the old battery pack working with a new BMS. Then order two more! I know the Daly BMS rated for 250A have 2 gauge wire, but I don't have a clue how their numbering scheme works. I did figure out why mine doesn't count cycles, they sent me a...

    JBD SP8S004 8S 24v 150A BMS

    I have the 150 amp JBD on order. But 150 is actually the highest I will draw for my use. The Eve cells are very consistent, 5 amp hours below 3.0, and 5 amp hours above 3.4. That's measured discharge below 3.0, and measured charge in above 3.4v, I'd have to look at the data, but I think...

    Power monitor with surge recording capability?

    I have no problem paying the money for a Fluke, you often get what you pay for. If the Kaiweets doesn't work out, I'll try calling Fluke and see what they recommend. I've been very happy with my Fluke meters, had a 75 for about 35 years (Reagan was president when I bought it), then it...

    Power monitor with surge recording capability?

    Thanks, I've seen good reviews of other Kaiweets products and the price is right. I'll give it a try.

    JBD SP8S004 8S 24v 150A BMS

    Just as an FYI, cells can be over 3 volts and be less than 2%. 3.0 to 2.5 is approximately 5 amp hours. 3.4 to 3.65 about the same.

    Power monitor with surge recording capability?

    I'm trying to find a product that will record the highest surge used by a device (like an air conditioner or refrigerator). Does anyone have any suggestions, or products to avoid? I'd prefer something like a power line monitor for 120v AC, but would settle for a clamp meter that captures peak...

    16 New EVE LF280N cells from Wan Amy

    I paid with a virtual card number from Citi. Went straight through, everytime. A lot of people report having to send copies of their ID, that's why I recommend the virtual number. I just wanted to remind everyone (once again), Amy does have a deal for forum members. Please use this code...

    How do i capacity test with no equipment?

    https://diysolarforum.com/resources/daly-sinowealth-software.103/ I've checked and these are the same software and drivers Daly makes available. It's just easier to find here. There is a lot here in the resources section. https://diysolarforum.com/search/367098/?q=Daly&t=resource&o=relevance

    How do i capacity test with no equipment?

    Yes, I haven't been playing with mine since it is out in the garage. I just set up a headless (dummy HDMI plug) Intel NUC, so I will probably start playing with it soon. I'm no expert, I just plug things in and try to figure them out, same as you.

    How do i capacity test with no equipment?

    I would have to search on this forum. It was someone here on this forum, and he gave details about it, and how to set some things. Specifically, there is a "noise" setting that helps with the jittery results. It isn't called noise, but from memory, that was pretty much it's function. I know you...

    More DALY smart BMS issues

    No, so far I haven't been able to figure out their model naming scheme. They really need to get their act together, simplify, and standardize, otherwise another vendor will come in and take their market share.

    How do i capacity test with no equipment?

    Two types of shunts, two methods of "calibration". If you have a higher capacity shunt, notice that it seemingly has a notch cut out of one of the bars? That is the calibration, totally automated process, sends a current, measures how much out of tolerance, and adjusts the notch size...

    More DALY smart BMS issues

    Yes, that sounds like a defective BMS. Daly customer service sucks, so be prepared for a problem. I hope you used a credit card, otherwise they have little incentive to replace it, and will try the "jump through hoops" until they hope you give up.
