    Type determination 2x unknown baby-blue: TP ICR18650 MA2GG27 & DLG 3AA Z 18E26 171106

    finally I tested all of the DLG cells (round about 160 new pcs) end they seem to be 2.600 or 2.700 mAh cells. I can't say exactly because the variety was very huge. They capacity spreads from 2.500mAh to 2.850mAh and most are somewhere between 2.600 and 2700mAh I did not use them in my...

    Home PowerDrive V2 - Germany ** 33+ kWh ** Big Power ++

    good video, but it is not an BMS, this is a balancer. It's a big difference and important to know, especially for newbies who think, an BMS is optional when using Li-Ion. It is not, an BMS is mandatory. But an balancer is optional

    adjustable Cheap Chinese Active Balancers

    unfortunately I have to say, that two of the small BMS JK-BD6A20S-10P are dead after a few weeks of usage in my 16s powerwall at the garage both seem to have "lost" some batteries. The first BMS lost batteries no. 01, 02 and 09 I first checked the cable connections. I checked it twice and...

    not all sellers do have the dongles, you will have to find one which is selling them. ICGOGOGO for example sells these adapter on Ali

    JK-B1A24S / JK-B2A24S Active Balancer

    could you establish the BT connection over a long time? When I connect via smartphone to the BMS the connection gets lost after several minutes of not using the app

    Limiter inverter with RS485 load setting

    did you order the whole meter? I asked several sellers on Ali for a single clamp sensor and one seller did an article specially for me with single clamp sensors https://de.aliexpress.com/item/1005002554200451.html Another way could be to use the clamp sensors from the SUN GTIL and this board...

    I used 2mm metal plate

    for me the 2mm metal plate is perfect. Strong enough to hold the 16s100p system and it could even hold more without any problems. And thin enough so I can bend the metal with a hammer. I would build it another time in the same way.

    18650 Garden-Powerwall with 50KWh in Germany

    Hi. I guess the BMS can't limit the current in the way you want to. The value "max. current" is a hard limit like a fuse, not a limitation which smoothly drops the current down to this value. If the "max current" is higher then the value you set (for at least 10 seconds or so) then the bms will...

    Limiter inverter with RS485 load setting

    This sounds very good :) Maybe it is the right direction to a 3-phase meassurement for the little SoyoSource

    hmm, but why? Maybe heat problems? Bad contacts / screws not properly tight?

    Limiter inverter with RS485 load setting

    I saw this just two weeks ago. For me it seems like it's nearls the same like the "old" one. Identical connections, identical clamp sensor, identical values are shown. Just new case and I guess they improved the possibility to add more inverters in parallel because of the four new LEDS at the...
