Description

Li-Ion Battery 2S1P – 7.2 V / 5000 mAh – LG 21700 Cells
Technical Data – Li-Ion Battery 2S1P

Configuration: 2S1P → 2 cells in series, 1 in parallel
- Series → adds voltage: 3.6–3.7 V per cell × 2 = 7.2 V
- Parallel → adds capacity (here only 1 cell in parallel, so 5000 mAh)
Voltage: 7.2 V nominal
Capacity: 5000 mAh
Cell type: LG 21700 (cylindrical cell, 21 mm diameter × 70 mm length)
Protection & Safety:
- Built-in protection circuit (BMS) with max 4 A
- Temperature monitoring with 10 kΩ NTC sensor
- Protects against overcharge, overdischarge, and short circuit
Connector: Cable with JST XH3 plug
Certifications & Compliance:
- UN 38.3 – transport safety according to UN regulations
- CE compliant
- Meets EU battery directive
- RoHS-compliant cells

Term Explanations:

2S1P: “2 Series, 1 Parallel” → doubles the voltage, capacity is the same as a single cell.
NTC 10 kΩ: Temperature sensor whose resistance changes with heat – protects cells from overheating.
BMS (Battery Management System): Monitors charge, current, and temperature – prevents battery damage.

I can also calculate how long this battery would last at different currents or its maximum power output based on the 4 A protection if you want.
