Do you HAVE to use a compatible Battery/BMS for MultiPlus-II / EasySolar-II for it to work?

I'm thinking of creating my own LiFePo4 battery - with it's own BMS for safety, and use this on a MultiPlus-II or EasySolar-II.

Do these products NEED a proper supported battery with BMS-CAN interface?
Or does it only mean that I have less 'features' I can view on the system?

Would the Victron Battery Monitor be useful for this? I.e. does it provide information to the system for this type of situation? ("unsupported" battery)

I believe I should also look into REC-BMS as this seems to be supported by Victron and could provide me with a better integrated system.

Thanks for the advice,
Phil.

No, you don't need a "compatible Battery or BMS".
You can also use the "two wire BMS" assistant with signals for "cell high" and "cell low".
A BMV is useful in such a system because without the SOC will jump to 100% if the "cell high" signal is active.
