3.7V (3.6V) Lithium Batteries

Can I Combine Multiple 3.7 V Li-ion Batteries in a Pack?
✅ It is not recommended to connect multiple 3.7V lithium batteries in series or parallel without careful matching. Pairing cells of different capacities, such as 3.7V 2200mAh with 3.7V 2600mAh or 3200mAh, may work temporarily but carries significant risk. Even connecting two identical 3.7V 2000mAh cells in parallel is generally discouraged unless done with proper expertise and protection circuits. Always ensure cells are properly matched and monitored to avoid safety hazards.
