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.

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.
Build Details
| Cell formats | 18650, 21700, pouch, prismatic — spot-welded nickel/strip and busbar construction |
| Voltage / capacity | Built to spec — single cell through high-series/parallel configurations |
| Integration | BMS, protection, balancing, charging, power distribution, custom connectors |
| Construction | Heat-shrink, hard-case, potted, and sealed assemblies |
| Testing | Capacity testing on calibrated electronic loads, DC IR / ACIR, per-pack data |
| Documentation | Lot and date-code traceability, Certificate of Conformance, SDS, and UN 38.3 support — provided to the requirement of the build. |
| Shipping | 49 CFR hazmat trained — lithium battery ground shipping (UN 3480 / UN 3090) prepared and labeled in-house. |
| Quantities | One unit through pilot and production runs. No artificial minimums; every project reviewed for fit. |

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.
Most quotes are answered within a few business days.
