Thanks for the info.
For the other problem I don't see any solution on what should be the 'updated design' page (
https://www.mobile-solarpower.com/design-your-own-12v-lifepo4-system.html). It advertises to use the Victron MPPT charger, but it lets the BMS disconnect the MPPT charger from the battery in case the BMS sees something wonky. That might damage the Victron charge controller as it is still connected to the solar panels .
I think the only good solutions are:
- Disconnect the Victron 's solar connection with a relay (maybe that unused victron BP
![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
)
- Hook into the communication port of the victron and tell it to stop charging when the BMS detects a problem with the cells (I am guessing such a command exist or another way to trick it into stopping loading by playing with threshold voltages).
(in normal conditions the Victron will stop charging out of itself and you can connect it directly to the battery, it is just in extreme corner cases when a cell goes bad that it matters)
Unless I am missing something.
