Custom Lithium-Ion Battery Packs

Custom Li-ion packs built from 18650, 21700, pouch, and prismatic cells — the highest energy density for the weight, for equipment that has to run long between charges.

Where Li-Ion Fits

Lithium-ion is the default when energy density and cycle life matter more than absolute lowest cost — portable equipment, unmanned platforms, instrumentation, and powered devices that need maximum runtime in minimum weight. BAM builds Li-ion packs from cylindrical (18650, 21700) and pouch/prismatic cells with spot-welded nickel or busbar interconnects, integrated BMS and protection, balancing, and the connector and form factor the application requires. Allied-nation cell options are quoted where sourcing requirements apply.

Lithium-Ion Questions

Which cell should my pack use?

Depends on the load and the space — high-capacity cells for runtime, high-drain cells for current. Send the discharge profile and envelope and the quote recommends a cell.

Can you match an existing Li-ion pack?

Usually — send the original or its label and dimensions. Reverse-documenting produces a drawing you keep.

Do you build high-voltage series packs?

Yes — high-series configurations with appropriate BMS and protection are standard work.

Can you document cell origin?

Yes — where a program requires it, packs are quoted with documented component source, country of origin in writing.

Send your Li-ion spec or the pack it replaces.
