Why Build With AmpBird
Everything for a safe, reliable DIY pack.
Complete Kit in One Box
Cells, BMS, busbars, terminal hardware, and wiring -- everything you need to build a working battery pack.
Grade A Matched Cells
Cells are capacity-tested and voltage-matched as a set, so your pack balances faster and lasts longer.
Pre-Programmed BMS
The included BMS ships configured for your cell count and chemistry. No laptop, no parameter guesswork.
Save vs Pre-Built
Building your own pack costs significantly less per kWh than a finished battery -- with the same Grade A cells.
Custom Capacity
Choose your cell count and configuration to build exactly the voltage and kWh your system needs.
Full Build Documentation
Step-by-step assembly guide, wiring diagrams, and torque specs included. Support if you get stuck.
Everything you need in one box
What's Included
⚡ Cells sold separately — choose your capacity and brand
Why build your own?
DIY vs Pre-Built
Works with popular cell sizes
Cell Compatibility
Our DIY enclosure is compatible with standard prismatic LiFePO4 cells from 280Ah to 330Ah. Same form factor, same M6 terminals — just pick the capacity that fits your needs and budget.
Compatible with all major Tier-1 cell manufacturers. Enclosure fits standard 17472 format prismatic cells.
Build your battery in 5 steps
Assembly Guide
No welding. No special tools. No electrical engineering degree required. If you can assemble IKEA furniture, you can build this battery.
Prepare Cells
Top-balance your cells to within 0.01V. Arrange them in the enclosure with separator sheets between each cell. Torque M6 terminals to 5 N·m. Double-check polarity orientation before proceeding — getting this wrong is the easiest mistake to make and the hardest to undo.
Install Components
Mount the BMS onto the pre-drilled bracket. Install the DC breaker into the front panel cutout. Connect the LCD display ribbon cable to the BMS communication port. Secure the busbars across cell terminals in the correct series/parallel pattern shown in the wiring diagram.
Connect BMS
Attach balance leads in order from B0 (cell 1 negative) through B16 (cell 16 positive). The wiring harness is pre-labeled. Plug the BMS temperature sensors onto the designated cell surfaces. Connect main negative and positive leads through the DC breaker. Before closing the circuit, verify all balance lead voltages with a multimeter.
Configure Inverter
Power on the BMS and verify all cell voltages on the LCD screen. Set BMS parameters via the JK app: capacity, cell count, voltage limits. Connect the CAN/RS485 cable to your inverter. Select the matching protocol from the BMS menu. Perform a test charge-discharge cycle at low current to confirm communication and cutoff behavior.
