I'm looking to download the app for my Heltec BMS smart Active balancer. Could you please provide me with the relevant link? It would be great if you could send it to my email, so I can access it easily. Also, if there are any instructions or additional information concerning the app that would help in the setup or usage, please include those as well. Your assistance in this matter would be very much appreciated. Looking forward to your quick response!
