| Pros | Cons |
|---|---|
| Lower cost | Less modularity |
| Less components | More complex |
| Funnyer | Balancing can be tricky |
| Pros | Cons |
|---|---|
| Modular | Higher cost with lot of cells |
| Reusable | More components |
| Simple and fool proof | Not our usecase |
| Kinda fun too | Not much monitoring-only chips |
For our project the big chippy seems the best.
