Welcome to our 12.8V 32700 LiFePO4 Battery Pack Series. Built on a strict 4S (four cells in series) architecture, this series delivers a stable and highly efficient 12.8V nominal output, making it the perfect direct drop-in replacement for traditional 12V lead-acid batteries. Available in capacities from 6Ah to 24Ah (4S1P to 4S4P), these packs utilize high-quality Grade-A 32700 cylindrical cells with a guaranteed true-rated capacity. The series includes specially designed compact space-saving layouts, including 3x4 Rectangular and 4x4 Square configurations, to fit perfectly into tight equipment enclosures. Equipped with a built-in smart BMS and offering over 2000 deep discharge cycles, these batteries provide a lightweight, safe, and ultra-durable power solution for outdoor solar lighting, 12V DIY projects, and portable energy storage.
Direct 12V Lead-Acid Replacement: With a 12.8V nominal voltage, this battery seamlessly replaces old, heavy 12V lead-acid batteries in solar systems, RVs, and outdoor equipment (Note: use a LiFePO4 charger).
Flexible 4S Parallel Configurations: Capacity scales from 6Ah (4S1P) to 24Ah (4S4P). Special shapes for 18Ah (4S3P - 3x4 Rectangular) and 24Ah (4S4P - 4x4 Square) provide optimized physical dimensions for unique mounting spaces.
Built-in Intelligent BMS: Includes a highly reliable Battery Management System (BMS) offering complete protection against overcharge, over-discharge, overcurrent, and short circuits.
Ultra-Long 2000+ Cycle Life: LiFePO4 chemistry ensures over 2000 deep cycles (80% DOD), lasting 3-5 times longer than traditional lead-acid alternatives, saving money in the long run.
Plug-and-Play Ready: Professionally encapsulated with heat shrink tubing. Equipped with pre-soldered red (positive) and black (negative) leads for immediate installation.
| Configuration | Nominal Voltage | Rated Capacity | Total Cells | Physical Shape | Approx. Dimensions (L x W x H) |
|---|---|---|---|---|---|
| 4S1P | 12.8V | 6Ah | 4 Cells | Single Row | 12.8cm × 3.2cm × 7cm |
| 4S2P | 12.8V | 12Ah | 8 Cells | Single Row | 25.6cm × 3.2cm × 7cm |
| 4S3P | 12.8V | 18Ah | 12 Cells | 3x4 Rectangular | 19.2cm × 12.8cm × 7cm |
| 4S4P | 12.8V | 24Ah | 16 Cells | 4x4 Square | 12.8cm × 12.8cm × 7cm |
(Note: Manual measurement may have a 1-3mm error. Please verify with the actual product before installation.)
Solar & Outdoor Lighting: Solar street lights, garden lights, solar lawn lamps, security light systems.
12V Replacement & RV Conversion: Direct replacement for 12V lead-acid batteries in RVs, camper trailers, and boats.
DIY 12V Electronics: Robotics, motor controllers, arduino projects, and smart home devices.
Security & Backup Systems: Uninterruptible power supplies (UPS), alarm systems, access control, and CCTV cameras.
Outdoor Portable Power: Camping power stations, 12V portable fridges, and emergency lighting.
Q1: What does 4S mean in this battery pack?
A1: 4S means four 3.2V cells are connected in series, providing a nominal output of 12.8V. It is specifically designed to replace standard 12V batteries in electronic devices.
Q2: Does this battery come with a built-in BMS?
A2: Yes, absolutely. All packs are pre-welded with an intelligent BMS that protects against overcharge, over-discharge, overcurrent, and short circuits, ensuring complete safety.
Q3: What are the 3x4 Rectangular and 4x4 Square variations?
A3: These represent the physical layout of the cells. The 18Ah (4S3P) is arranged in 3 rows by 4 columns (Rectangular), and the 24Ah (4S4P) is in 4 rows by 4 columns (Square). These shapes are designed to adapt to different inner spaces of your equipment battery box.
Q4: Can I use my old 12V lead-acid charger for this battery?
A4: No, you should not. While it can replace a 12V lead-acid battery physically, the charging voltage is different. You must use a dedicated 14.6V (4S) LiFePO4 charger. Using a lead-acid charger may damage the battery or the BMS protection board.
Q5: How do I choose the right capacity?
A5: Evaluate the power consumption (in Amps) of your device. Use the formula: Runtime (hours) = Battery Capacity (Ah) ÷ Device Current (A). For example, if your solar light uses 1A, a 24Ah battery will provide up to 24 hours of runtime.
Free Shipping: Enjoy free shipping on all orders over $65. For orders under $65, the shipping cost is $8.99.
Delivery Time: Once shipped, orders typically arrive within 7–15 business days.
Easy Returns: We want you to be completely satisfied. If you're not, you can return your product within 30 days of receiving your order. Please ensure the items are unused and in their original condition. For return instructions, please contact our support team.
