    8S2P 24v Battery – Help needed.

    dnmun, Agreed, at the moment I just don't have the time or "electrical education" to keep on with this one, I have missed a few big dives already because my scooter was not ready. Winter is closing in fast around here, I do Ice dive but cannot use the scooter under there, so I will have all...

    8S2P 24v Battery – Help needed.

    dmun, No it never. Never has, and don't think it ever will. Pings suggested repair did not work also. (sent to you in PM) Going to shop for a new BMS. Moving on. Thanks for your help.

    8S2P 24v Battery – Help needed.

    I opened the DVM and adjusted it, and believe it is reading correctly, checked against my Eagle tree data logger and smart charger with digital readout they all measure the same voltage on the same battery. Have the battery back on charge and measured at the B0-B1, B1-B2 etc as you had...

    8S2P 24v Battery – Help needed.

    I measured across all the resistors, will need to remove the battery from its mount to access the cells to measure those (will post when this is done) On the resistors, I get these numbers while charging, I checked 3 times during the charge. If I am doing this correctly I found. Running from...

    8S2P 24v Battery – Help needed.

    dnmun, again many thanks. Your explanation above really helped, I now have the BMS connected correctly with the proper readings ascending from the black wire to the red. I have put it on charge to top up and balance, I have also begun to cycle it with a few shallow draws with my burn tester -...

    8S2P 24v Battery – Help needed.

    Thanks, I measured the black wire with the black probe on "B -" and get no voltage reading, the first reading of 3.4 is on the first white sense wire? Isn't that black wire and "B -" going " ground to ground" for a reading of zero?

    8S2P 24v Battery – Help needed.

    dnmun, Thanks for all you help. I have connected the sense wires I believe as you have described above, before I plug it into the BMS would you, or anyone with experience doing this be kind enough to confirm my wiring is correct ? I really don't want to leak all the secret smoke. ( a phrase we...

    8S2P 24v Battery – Help needed.

    Hello all, Thanks for the comments so far. I have constructed the battery pack and have soldered the wires to the BMS, so far so good. I am now ready to connect the BMS to the battery but before I start connecting the sensing wires, I do have a few more questions. 1- Can I add all the wires to...

    8S2P 24v Battery – Help needed.

    Here is the kit I was planning on going with,I will be using the connector plates and cell holders as a square block so I will not need wire except for the +/- connections and BMS connections. I will be using the BMS I added above not the one from the kit. (diag of wiring added below) I have...

    8S2P 24v Battery – Help needed.

    Hello, Thanks for the screen shot, I was one tab away. Hopefully this is it attached now, the configuration needs to be "square" to fit inside the scooter.

    Hello all, Just wanted to introduce myself and explain my reason for registering here. I live in Canada and am a cave diver, have been for many years and what brings me to your wonderful site is a project I am working on that could use a bit of input from an electrically educated group. I have...
