I agree this is not desirable.

The battery pack is the costliest part of this kit. You do not want to skimp on monitoring/protecting it at the individual cell level. It becomes even more important as the cells age and start to drift apart from one another in capacity/performance.

Even with the cheap, used lead acid batteries in the ForkenSwift, I would not be satisfied with a monitoring system that only showed me the performance of each pair of batteries. I want to know what each battery is doing to protect them from damage.

Sounds like they're just trying to cut costs.

But unless someone gives you a convincing technical reason the new setup (one monitor/balancer per pair of cells) is equal to the original (one per cell), I wouldn't be satisfied.
