Many 3rd party LiFePO battery modules that are not in fact Pylontech battery modules are recognised as Pylontech battery modules. This causes issues if the modules are 16S lithium cells, since the hard-coded CVL for the 15S lithium cell Pylons is 52.4V, and so the 16S modules can never receive even close to a full charge. An example is the CFE battery, which is recognised as Pylontech in the Cerbo GX, but is not a Pylontech module.
If there was an option to over-ride the hard-coded 52.4V limit, then the CVL called for by the 3rd party module can be observed correctly, in the case of CFE batteries, this is 56.1V.
