This sounds like a good feature. Monitoring only.
I'm a fan of bottom balancing, but I would feel better if the cell voltages were monitored.
I am not confident enough in my DIY fabrication skills to put a board on the batteries. I would likely INCREASE the chance of a battery fire instead of DECREASE.
Instead of replaceable fuses, would *REALLY* thin wire be better protection? It would take some experimenting to determine how small it would need to be. AWG #40 is the smallest that is listed in WIKIPEDIA here

That way if the insulation rubs off, or anything goes wrong in a vibrating, moving vehicle, the thin wire just melts and the short circuit clears. A small amount of damage but no battery fire! AWG #40 lists 8.5 amps for 32 ms ... I assume longer would melt it - which is the idea.
