Meet the new Sigma.
The new Sigma
Sigma is designed to be easy to install. Front-mounted terminals, a flexible build that mounts in multiple positions, and a compact footprint means the Sigma fits where you need it, including the underseat bay of your motorhome.
High capacity and high discharge currents, for setups that run heavier loads and bigger systems.
Run one unit or four in parallel. The system grows with you, without any change to the installation.
Front-mounted terminals make connections easy to reach and easy to work with, even in a tight underseat bay.
Most batteries force a compromise: you settle for less capacity than you wanted, or give up the space you needed for the rest of your system. The Sigma was designed to end that trade-off, with the capacity you’re after in a battery that installs where it suits you.
That changes what’s possible. The inverter and the charger go where you want them. And when you add solar, or a second fridge, or just want more days off-grid, the Sigma grows with your system.
CAN, CANopen, RV-C, Victron, LIN (CI-BUS, VW-LIN) and Bluetooth, plus three configurable IO contacts for inverter and generator control.
Precision cell matching, thermal management across extremes, proprietary software, data logger, and mechanical robustness that shrugs off vibration, shock and heat.
