- ✓ Over-charge, over-current, short-circuit and reverse protection plus equalizing charge
Cons
- ✗ Batteries not included; you must buy compatible 3S cells separately
- ✗ Correct cell choice depends on following the manual closely
- ✗ I2C monitoring needs your own code built from the online resources
- ✗ 5A ceiling can be tight for Pi builds with power-hungry USB devices
