I have AOlithium 51.2V 100ah batteries running in closed loop with the SRNE ASF-series inverter, and I see similar behaviour. When the batteries get full, the BMS sends a '0 amp charge limit' signal to the inverter to stop the charge. A few moments later (a minute or two, perhaps), the BMS...

I just purchased 4 of these for C$999 each, including cables and the mounting rack. Shipping was free to Vancouver, BC. Definitely a good deal.

I have the same inverter, but a 5KW version, and an old one. The old ones CANNOT do closed loop communication, and no firmware upgrade will change that. But, if you have a newer one, check your firmware; version 6.53 or higher is required for BMS communication. If your inverter has the newer...

I ran the datasheet through Google Translate, and converted it to "english." File attached. Chris

Thanks for the replies.... I'm starting to get a better understanding of the whole communication gamut. Would it be fair to say that using closed loop (BMS communication) versus a 'dumb battery' setup results in higher useable battery capacity? For example, on my equipment (AOLithium server...

3750mV is the factory setting to shutdown if a cell reaches that level. See that attached image.

I’d like to know the answer to that, too. Anyone? Chris

There must be something transmitting between the batteries...? Otherwise, how does the master know what the voltage is of the slaves in order to communicate an appropriate CVL / CCL to the inverter? For example, the master battery may be sitting at 54V with a CCL of 60A, but one of the slaves...

Thanks for that quick explanation. Now knowing what to look for, I was able to see my battery sending different "CCL" numbers to the inverter to control the charge rate. But what about the communication between multiple parallel batteries? What does the 'master' BMS communicate to the 'slave'...

Just make sure you are getting the correct size. Futronics makes two sizes, they look identical, but are not interchangeable. The smaller size (rated about 120 amp) is used on the AOlithium battery. Chris

I bought 3, then later bought a single. Free shipping on both. But perhaps that has changed in the last week? Chris
