Features: - Supports multi-layer overlay to increase power and capacitance. - Compatible with expansion modules; supports single-sided or double-sided battery configurations. - High-current wiring design for full-chip protection board and battery holder. - High conversion efficiency with multi-layer balancing capability. - Built-in over-voltage protection to prevent overcharge or over-discharge. - Voltage equalization function ensures consistent voltage across multiple cells, extending battery pack lifespan. - Protection board provides balanced equalization for the entire multi-layer battery assembly—no additional per-layer protection boards required. - Easy to install and operate; no special tools needed. - Installation: Mount batteries on the circuit board according to polarity markings. Avoid reverse installation. Specifications: - Item Type: Battery Holder with Protection Board - Material: Plastic + Metal + Electronic Components - Dimensions: 151 × 85 mm (5.9 × 3.3 in) - Color: As shown in image - Options: 1. Single-sided battery holder 2. Double-sided battery holder 3. Single-sided battery holder with integrated protection board - Rated Voltage: 24 V - Max Current: 40 A - Quantity: 1 PC Important Notes: - A 25.2 V charger is required for 6S battery charging. - Recommended charging current per layer: ≤ 2 A. Exceeding this may cause overheating (e.g., use a 2 A charger for one layer, 4 A for two layers). - Do not operate on metal surfaces; ensure proper insulation to avoid short circuits. - Batteries must be oriented uniformly (all facing upward toward the circuit board); interleaving is not permitted. - Verify polarity before connecting power supply—the board is clearly marked. - Battery not included. Measurement Note: - 1 cm = 10 mm = 0.39 in - Allow up to 1 cm variation due to manual measurement. Please confirm acceptance before ordering. - Screen settings may affect color representation in images. Package Includes: - 1 × Battery Holder with Protection Board Kit - Balance wires shown in images are not included.
