Forterra Project Sustainment or MAUL: vehicle auxiliary power

Bren-Tronics | Prime | HYPOTHESIS | Source research 11 October 2026

Dated evidence

Forterra MAUL and Rheinmetall Project Sustainment are active UGV prototype ecosystems.

Potential technical fit

Bren-Tronics ultra-high-capacity 6T batteries and field chargers may support silent watch, robotic mission equipment or service power; cannot assume traction battery suitability.

Relevant contact and routing

Forterra MAUL systems power engineer or American Rheinmetall UGV auxiliary power lead, routed by verified corporate channels.

Concrete next steps

Clarify auxiliary/mission power vs propulsion pack; ask for voltage, form factor, charge profile and environmental envelope before proposing pack.

Reasons not to pursue yet

Likely poor match if UGV uses proprietary vehicle high-voltage traction batteries; existing vehicle suppliers unknown.

Additional verification needed

verify exact product model/specs; identify engineering decision maker through sourced current record; establish if the work package is actually open; find fresh government/prime primary sources; corroborate integration pathway, competing incumbents and the contact route. If any gate fails, hold the brief.
