20A 8S LiFePO4 BMS for 24V-Class Battery Packs
The 6334-8S battery protection board is labelled for eight 3.2V LiFePO4 cells connected in series. It is intended for a 24V-class battery pack, with a calculated nominal voltage of 25.6V (8 × 3.2V). The manufacturer's label specifies a common charge/discharge port and a current rating of up to 20A.
Key Features
- 8S configuration for eight series-connected LiFePO4 cells.
- 3.2V nominal cell chemistry, as stated on the label.
- 24V-class / 25.6V nominal battery-pack application.
- Common-port design for charging and discharging.
- Metal cover, plug-in cell-sense wiring harness and attached black probe visible in the product photo.
- Clearly labelled B− and P− connection points.

Suitable Applications
Use in compatible 8S LiFePO4 battery-pack builds or repairs where the load and charging requirements match this board. Check current requirements and starting surges before selecting a BMS.
Installation and Compatibility
This version is for 3.2V LiFePO4 cells. Do not substitute it for a BMS designed for 3.7V lithium-ion cells. Have a qualified battery technician verify the cell-sense connector sequence and all terminal connections before applying power. Do not determine connections from wire colour alone. Use a charger suitable for the completed LiFePO4 pack.
Specification note: Balancing capability, protection thresholds, peak current, charge-current limits, temperature thresholds, dimensions and probe operation have not been verified for this exact model. No Bluetooth or app connectivity is specified.
