Dear Friends,
I'm writing this because I suffer with EA Sun battery communication for more than one month. My story: At the beginning of January 2024 I bought from EA Sun official AliExpress store inverter https://www.aliexpress.com/item/100...7A662Nfi&utparam-url=scene:search|query_from:
and 2 pieces battery packs type ibattery-ay-51.2v-100ah-jj: https://www.aliexpress.com/item/100....new_all_items_2007566926224.1005005490213604
Since the mid of January I started to try to establish communication between Batteries and Inverter. The seller after consulting with her engineer give various options that coudn't help mutch. She suggested to upgrade software of the battery and sent bin file. 15 days after order receipt confirmation seller stopped communication as I can't claim return and refund.
Finaly, today, after reading various forums and instructions in internet, I managed to upload the software upgrade in the one of the packs. After upgrade battery stopped working and give message: Connection Fail Will Close! Attahed to this post is a screenshot. Alarm LED flashes continuously. All battery parameters on its display are 0, i.e. capacity, current, cycles, current etc. Communication between the battery and PC BMS Tools is also impossible.
Before upgrade its capacity was 94%. I immediately disconnected battery from inverter and switched off.
I can't rely on support from the seller. Therefore, kindly ask you to help to put back the battery in running mode.
Thank you in advance!
