KBWaldron: thanks for the update. Due to a snafu at batteryhookup my delivery date for 4 modules has been delayed from today Mon. Nov. 18 until Wednesday/Thursday this week. Many apologies from Ryan. Ryan also confirmed that these batteries came from a large solar farm in Arizona where the company lost funding and went bankrupt and had to dismantle their battery storage setup ASAP to make room for a new tenant. Ryan said that the circuit board within the battery case is a proprietary BMU meant to communicate battery status to an external overall supervisory computer system. Ryan and Tom are in touch with one of their clients that claims to be able figure out how to communicate with this BMU directly without removing it. Ryan guesses if this information is going to be available it will happen in the next two weeks or so. If it does materialize, Ryan will send out an informational email to everyone that purchased these batteries from them. If that does not happen, then the only option is to do what David Poz did in his video and bypass the BMU to get at the cell sensors directly. Too bad we cant figure out a way to use the temperature sensors as well. I have finally had contact from a person that works for the BYD Battery Box group by emailing to: batteryboxgrp@byd.com . His name is Sean Li. He said originally that he was not aware that BYD ever had a battery like the one we are buying. I sent him the battery information and the model number ABSSM. I am hoping he will research it on his end and be able to provide us more information on this battery and possibly how to operate the BMU. More later as it comes in.
