    Extend JK bms Bluetooth or other options

    I see that most comments are workarounds. Raspberrry pi, Solar asistant, home asisstant, venus and etc. I have and use most of it. But the question is simpler. How to just extent BT range? Just too put reveiver/transmiter on one end and another part and on the other part. That's bout it :)

    JK BMS: canbus AND/OR rs485

    I solve this problem. They call have this CAN/RS port. That port are preprogrammed from factory. You only can have one of them. BUT.... there is GPS port and it ALWAYS in RS mode :) (except you have to buy adapter ±10USD). So so you can order CAN version, but also have RS :)

    JK BMS 200A (350A peak). 2x 7AWG. HOW?

    Yeah... i'm somehow did not think about length. That's right. They are very short. Maybe super fine strand also makes sense. But silicone jacket? :) It does not acting in power transmission :) Why you mentioning it? :) Higher temp. resistance?

    JK BMS 200A (350A peak). 2x 7AWG. HOW?

    JK BMS, rated at 200A current with 350A peaks. Have two 7AWG cables on B- and two 7AWG cables on P-. How this is possible? Does anyone had a problems with it? 7AWG cable rated to 30-40A. Two of those will double accordingly 60-80A. Is it safe to use?

    Charging speed (bottom balancing) 14A instead of 24A

    How the hell i could miss that!! :D When was buying this bench charger, i've ordered it with 25A cables. So i was sure, that all ok with cables. But you are right, alligator clips have very small area of contact. Replaced now with 7AWG cable with ring terminals, and can push all 24A. can't...

    Charging speed (bottom balancing) 14A instead of 24A

    i'm totally confused. I have RIDEN 24A charger. I can charge at 3.65V and 24A speed. My LiFePO4 cells arrived at 3.29 and 3.30V. This means they are far away from full. I connected 16 of these cell together (all positives together and all negatives together), so i have one very large 3V...

    JK-B2A24S20P BMS Verify Password to enable settings change

    I also was thinking on how it can be time related. The only thing i can think about is that your BMS serial number is bounded to the phone application. And that code is generated for your application (if it's on the phone, it should have access to internet). So maybe it kind of your applications...
