I order the LCD Screen from IC GOGOGO Store because they had a clear way to confirm the screen I ordered match up with the JK 8S- 24S version of BMS I ordered from the JK BMS store, Did not take time to dialog; just went for getting in my order..

Got my JK BMS wired up now, with App working on Android phone, plus the 4.3" LCD working... I found the icon on top tight for toggle change to English. Nice to get past this little detailed hoop jump.

Just booted up my first JK BMS B2A224S20P, it's working since about an 2 hours ago. Scanning to fill in some blanks for my curious side of me. This Forum Is An Awesome Educational and Info. Resource. Thanks :+) Updating with this 9.12 picture of my Portable Generator Project for my girlfriend's home, for no grid cycles (thinking solar will come later). Got JK BMS fully configured and dialed in. That little black box charger in picture is a $40 .. 48v 7Amp (says 10A. 8A) LiFePO4 Charger from Amazon I bought as a backup charger; for accidental below cut offs battery volt challenge times (happen to me more than once); and the little charger works great/ got 58.3 volts showing from an initial 52.6 volts /... while testing this charger and my BMS, ... for maybe 25 hours of off and on cycles. Gona hook up, and be grid charging @ up to 50 amps via that EG4 3000 unit soon (I believe 50Amp charging would need 30 Amp rated input wires. ... So ... Making Progress ; Lots of Details; and eventually putting this on a 4 wheel wagon before powering up essential circuits via Transfer switch n Box. ... I have lots of other projects all around me; & this one is fun. ... I like this Hobby ... :+)
