Description

DIY Battery Kit - Lithium Iron Phosphate (LiFePO4) 12V 34Ah 408Wh

Complete kit to assemble your own high-performance and compact battery using cylindrical cells.

● Capacity: 34 Ah
● Energy: 408 Wh
● Nominal Voltage: 12 V
● Approx. Weight: 4 kg

Material included in the kit:

  • 8 Headway 40152S 3.2V 17Ah cylindrical cells: High-power cells supporting a high discharge current. Individually tested before shipping to guarantee perfect pack balancing.
  • 100A BMS: Regulation circuit (Battery Management System) with a common charge port (17A max based on cell characteristics) for independent charge and discharge cycles.
  • 8 battery holders / interlocking matrices: Used to securely fit and lock the cells together to form a compact and highly robust block.
  • 14 busbars: Made of pure copper with a thickness of 2 mm, specifically designed for Headway cells.
  • Power cables: 8AWG cross-section | Standard length: 40 cm (lengths can be modified upon request).
  • Suitable fuse and complete hardware set

Required tool:

A simple screwdriver is enough. No prior knowledge of electronics is required. The complete wiring diagram and schematic are provided with the purchase.

Advantages of DIY LiFePO4

  • Top performance: Uses the best LiFePO4 cells on the market, ideal for space-constrained projects requiring high peak currents.
  • Easy & modular installation: Within everyone's reach, easily adapting to any setup.
  • Simplified maintenance: If a cell weakens over the years, you can replace it individually without changing the entire pack.
  • Extended lifespan: Cylindrical Lithium Iron Phosphate technology offers between 2,000 and 3,000 charge cycles, compared to 600 cycles for classic Lithium-Ion and 300 cycles for lead-acid batteries.
  • Cost-effective & Durable: Perfect and highly advantageous direct replacement for your old lead-acid batteries.

Applications

This compact kit is particularly suitable for the following uses: boats, solar sailboats, ATVs/quads, autonomous vehicles, solar installations, agricultural equipment or vehicles for organic farming, industrial floor scrubbers, marine applications, aerial work platforms/lifts, golf carts, wire-guided vehicles, wheelchairs, and prototype development.

⚠️ Precautions and Conditions of Use

The battery pack must be stored in a dry and ventilated area. The nominal current of the cells is 0.5C (17A) for charging and 2C (68A) for continuous discharge, with a peak tolerance (0.5s) of up to 6C (204A).

Although the absolute operating temperature ranges from -20°C to 60°C, we recommend an optimal storage and usage range between 0°C and 50°C to maximize the lifespan of your cells. The metallic terminals must be properly insulated and protected to avoid any risk of accidental short-circuits caused by a falling tool.
