-There are several elements to the BYD system. There is a single central Battery Management Unit (BMU), this is able to communicate to up to 32 individual 2.5kWh battery modules. Each of the battery modules also has their own Battery Management System (BMS) to individually protect the cells, and report back to the BMU, which collects data from all of them and reports it to the [[venus-os:​start|Venus-device]].+There are several elements to the BYD system.

-This is important to consider that if the BYD battery has not yet been detected by the [[venus-os:​start|Venus-device]], it may turn itself off without the signal for it to “stay alive”. If the battery turned off midway through a firmware update the consequences could be serious. Ideally the connection between the CCGX/Venus GX and the BYD is established first, and the battery will continue to operate. If you plan to use the BYD to power the inverter/​charger for the firmware update process, first ensure the battery is connecting to the CCGX/Venus GX and wait ten minutes to ensure its all operating correctly. +This is important to consider that if the BYD battery has not yet been detected by the [[venus-os:​start|GX device]], it may turn itself off without the signal for it to “stay alive”.

-If this is not possible, such as a firmware update is required on the CCGX. Then it is possible to temporarily run the battery without shutting down by disconnecting the RS485 cable that connects the battery module to the BMU. This is very temporary situation until you can connect the [[venus-os:​start|Venus-device]] for normal operation.+If this is not possible, such as a firmware update is required on the CCGX.
