    All has been fine for days now. I even lowered the balancing current to 1 amp from the 2 amp. Externally fused at 3 amps now.

    Dead cell sample lines on JKBMS JK-B2A24S JK-BMS >> FIXED

    Hmm -- overlooked the obvious ... I can put an inline fuse in the external red wire(s) on the cell(s) that I had to jumper in the black box. I'm thinking the glass tube type AGC 2.5 or 3 amp I can only imagine how many of these 'blown fuse' BMS units are piling up and getting tossed out !! Over...

    Would anyone consider this surface mount fuse to be a bad design ? When a fuse pops are you really gonna ship it back to China for repair ?

    Can you post a photo of your board and where you found any spare fuse links ? Or try to describe how I can be sure I'm not pulling one that's 'in play' Hmm, maybe you are suggesting since I use cells 1 to 17, just steal a link from 18 to 24. I've never gotten any surface mount solder tools...

    What is the cause of our 'fusible links' blowing ? Is it fatigue ? Poor design ? Are fuses there to protect the bigger silicon based device(s) ?

    Off-grid: illegal in Florida?

    I live in Florida, Pasco county. I need the grid to deliver high loads in the summer. But when the grid goes out I do make it with the 42 kw of storage I got here.

    Many have 'Duke' as their utility provider -- your Duke is a different kind of energy I see !

    I see 500k resistance across resistor on cell 1 sample all others are 0.5 ohm Did you just jumper it ? Or bother to insert half ohm. Or is there a fuse for that part size that you used ? If I jumper that part it is on the bottom side -- inclined to use the ole 30 gauge wire wrap solid wire I...

    The left most pin is B- B1 is next and must go on trace on the other side B2 is 3rd and I don't see any blown characteristics in the photo I will get a meter out tomorrow and see if I see something that way

    wow -- i hate soldering surface mount I first soldered in 1968. will look as the seller is anal and expects a trans pacific shipment and me paying to return seller claims 2 month swap, after that must return I ordered another one and might just go down the slippery road he is forcing, etc

    When I substitute another identical JKBMS unit it shows fine, just this one. It stopped correctly reporting while we were at sea, on a cruise for 9 days.

    JKBMS model JK-B2A24S I am finding the seller 'useasy' on ebay WON'T HELP ME. I bought it from him six months ago, and it has the two broken inputs. He claims to be acting as AGENT for the manufacturer and won't allow me to diagnose dead cell inputs with manuf. Ebay itself blocks direct...
