Hello,
New here, I am about to expand my battery with 3 more.
My current batteries are version D I was told this is V2.0 when installed, however now not so sure.
Anyway my main issue is I have ordered 3x V2 battery and now not sure if my BMS is V2.
Anyone know how to tell the difference?

Have managed to find my whole system is V1 not the V2 my installer Dual Fuel Solutions told me they would be installing!

Yes correct, the Ver D batteries are V1 not V2.
The V2 batteries you have ordered won’t work with that pack, unless you change the BMS for a V2 and then update all the firmware, but mixed packs are not as stable/practical as packs of the same type - it would be much, much easier to change your order to V1’s
