    unless you work in a powertool service-center or rental place, it's too expensive to justify

      Too steep for my pocket book TBH.

        I think I've been duped again...

          I might get one but I am going to try to find a cheaper one than this one

          What I impressed with is that it has a voltage reading on each battery cell which is a plus when you are testing BMS balancing protection boards

          I found an alternative battery meter for BMS balancing protection board testing

          1S-24S Lithium Battery Pack Single Cell Voltage Tester for Lifepo4 Li-Ion LTO

          https://www.ebay.com/itm/23492891374...3ABFBMtPrFj6Ni

          I will also be buying the adapter board as well I will just have to build a testing jig for this setup

            Finally arrived today in the mail I powered it up just to make sure that powers ON and that the device was not damaged in any way

            Here are the results from the battery packs that are for the battery operated air compressor

            This will do exactly what I want it to do I just have to make the testing jig so I can hook up the the SkyRc battery charger to it and or a BMS balancing protection board to see how well it behaves in the balancing mode

            The left side of this display has some very interesting data that can be very informative about the battery pack

              Well… that’s more like it! The pricing is much better too and it comes with a display! Cool!

                How do I determine what type of JST pitch and spacing this connector configuration this that is used on this BMS balancing protection board

                What I do know is that it is 24 pin JST type connector

                Because I want to modify the connector so that I can put this single cell voltage in series with the BMS

                I could buy two 12 pin BMS balancing protection boards for the JST connector but I really do not have a use for 12 pin BMS protection boards right now

                  use a caliper to work out the pin spacing

                    I do it same way as stj. I’ve got the pins and work out the size and spacing using a calliper.

                      I looked at Digikey website last night for JST connectors and found some but there are several different types so I am not sure which style it is

                          Well I found the active battery balancing board that I going to use with the device that I bought earlier

                          https://www.ebay.com/itm/38554037757...Bk9SR7SbkJG-Yg

                          Going to buy the 24 cell version and a 2 , 3 , 4 , 5 , and a 10 cell version because I am using these battery cell counts right now

                            There is a picture of the connector on the website link and the picture below
                            JST XH Pitch 2.54mm

                            As you can see in picture below this battery pack is not very balanced this is why I need a balancing board for battery packs that I going to use my own charging device

                              The board uses ETA3000S2G Inductive Cell Balancer IC. SOT23-6 marking GIYW.
                              Not a bank of 1R0 resistors lol.
                              It seems to take energy from a higher voltage cell and transfer to a lower voltage cell. Should make much less heat and waste less energy I suppose.

                                I will find out in a month or so because it might not be until next week before I will order the items that I mentioned above

                                When I get this device I will write a review about it and how this system will be setup and configured stay tuned for updates when they come available

                                  I bought a couple more of these boards and going to modify them so that I have the wires as the output side not the input side

                                    Well did have some time this early morning to make up some connectors “see the description” as you can see in the picture below
                                    “DIY Toy JST XH Pitch 2.54mm 2~12P Connector 100/200/300mm 26AWG Cable Wire”

                                    I also ordered the same type except that they are 2.00 pitch not the 2.54 because I both types of connectors for some BMS protection boards that I have and I want used them and watch them charge and discharge when testing them

                                    I have to work on the charging system for this testing station but I have to wait until I have all of the cables and connectors made up then I can concentrate on the charging stations going to try to include the broken battery testing machine that the charging/discharging circuit does not work properly and has been removed for the enclosure

                                      Well I found a stand for my battery BMS voltage monitoring board in the one picture you will see a
                                      ( red circle around the )
                                      tablet holder that is suppose to on this stand but instead of doing that I put the battery voltage monitor on it instead I used two fender washers and two rubber washers and sandwiched the plexiglass in between the washers

                                      Now I need to spend some time working on the switching power supply and it hookups to the battery voltage monitoring board

                                      If anyone is interested in the tablet stand please let me know and I will post a website link on EBay to where you can get one

                                      One note not all tablet stands are the same and some of them do not have it where you can take off or just not use the tablet holder itself and just use the stand

                                        I finally did receive the correct JST PH2.00 pitch cable female ones that is only ones available from this eBay seller and also only offered the male circuit board connector

                                        I did place a second order a few days later from the same seller that still has some pin versions available and all that the seller had left

                                        Now I have to battery monitor/BMS connectors for the 2.00 pitch that are on battery pack
