• E-bike pack — 13S 18650 + 48V BMS — see E-Bike BMS
• Portable Arduino project — 18650 + TP4056 + boost converter to 5V

How to Choose a Charger Module

1. Single cell — TP4056 is the standard choice; add protection version for over-discharge
2. Solar input — CN3791 for MPPT tracking; handles varying panel voltage efficiently
3. Multi-cell LiPo — dedicated balance charger; never charge multi-cell packs without balancing
4. Fast charging — select CC/CV modules with higher current rating; ensure cell can accept the rate
