Not an issue. In your GX settings the BMS SOC will be used if in Auto mode, but you can just change that and pick the BMV’ SOC to guide the systems limits.
Just be aware that your SOC will then not handle changes when cell imbalance happens when you do that (best to go read the thread on that details and make sure you know why the BMS SOC is better even though it might not work for your scenario so that you know what issue to look out for).
I have to disagree. This BMS SOC is one of the better ones. It use a shunt and is pretty accurate.
If you compare it to the BMV then you are missing the hole thing about lithiums. You are still thinking in terms of lead acid batteries and you are trying to limit your lithium to work like a lead acid.
Here is a post explaining the SOC from the BMS.
Screenshot are in that thread about how to change from the BMS SOC to BMV SOC and back. (few posts down)
