Description
3S Lithium-Ion Battery Protection / BMS Board, 10 A
Protection board for a three-cell series lithium-ion pack, such as a pack made from 18650 cells. The source lists short-circuit, overcharge, over-discharge and overcurrent protection.
Important: the source calls this a charger, but describes a protection board and does not specify a complete CC/CV charging input or control. Do not use this board alone as a charger. Use a charger designed for the exact 3S cell chemistry and pack configuration. See the Analog Devices charging reference.
Specifications stated in the source
- Three cells in series, listed as 3.6–3.7 V per cell (10.8–11.1 V nominal)
- Maximum discharge current: 10 A
- Maximum operating current: 5–8 A; transient current: 9–10 A
- Source excerpt separately claims a maximum 10 A charge current; the detailed specifications do not clearly confirm this
- Charge cutoff: 4.25–4.35 V ±0.05 V (the source does not clarify whether this is per cell)
- Discharge cutoff: 2.3–3.0 V ±0.05 V (the source does not clarify whether this is per cell)
- Operating temperature: −40 to +50 °C
- Standby current: under 6 µA
- Internal resistance: under 60 mΩ
- Dimensions: 50 × 21 × 1 mm
- Price: MAD 35
Verify the cutoff basis, charger compatibility, cell ratings and wiring for the exact board. Do not assume the 10 A figures apply to every operating condition. Incorrect lithium-ion charging or wiring can cause fire or injury.
