Saltra LFP / Busbars and Compression
Busbars and compression are not random hardware.
Large prismatic LiFePO4 cells need the right terminal spacing, hardware, insulation, current rating, and mechanical support. Bad fitment can make a good cell build look unsafe.
Buyer pain point
The parts must physically fit.
A cell may be correct electrically but still fail the build because the busbars, holes, screws, compression plates, or case do not match.
Busbar fitment
Busbars must match terminal type, hole spacing, current rating, copper thickness, and the cell layout.
Compression
Many large prismatic cells benefit from controlled mechanical support. The correct fixture depends on cell dimensions and application.
Insulation
Fish paper, terminal covers, separators, and edge protection help reduce accidental shorts and improve build cleanliness.
Case or open build
A 12V portable build and a 51.2V storage build may need very different case, rack, or compression approaches.

What Saltra checks for mechanical fitment.
Build logic
Mechanical build checks.
| Item | Why it matters |
|---|---|
| 4-cell 12V build | Needs correct series busbars, insulation, and a clean compression/case plan. |
| 16-cell 51.2V build | Needs more careful layout, busbar routing, compression, cable exit, and serviceability. |
| Random long busbars | Should not be used unless hole spacing, current rating, and layout are verified. |
Next step
Do not guess the build.
Tell Saltra what you are building, your target voltage, application, capacity goal, and whether you already have an inverter, charger, or BMS. We will use that information to recommend a cleaner battery build path before you buy.
