Boat battery Moduloo Ax & Bx

for AUVsfor ROVfor electric motors

Overview
The Moduloo Ax & Bx lithium battery range is engineered to deliver high energy density in compact, lightweight enclosures for mobile robotics, autonomous vehicles and other mobile applications. Modules are plug-and-play, can operate standalone or be connected in series and parallel to scale voltage and capacity according to integration constraints.

Versions

• Moduloo Ax: ultra-compact, lightweight modules for weight- and space-constrained applications (IP54 enclosure options).
• Moduloo Bx: higher-capacity, rackable and IP65-rated variants for harsher environments (up to ~2 kWh per module).

Key features

• Designed and manufactured in France.
• Certifications: RoHS, CE, UN 38.3 (transport compliant).
• Modular architecture enabling series/parallel connectivity and multiple front-panel options (A–D for non-rack; E–H for rack/blind-mate).
• Communication: CAN 2.0, SMBUS & I2C (model-dependent).
• Sustainability: compatible with TYVA Refill replaceable-cell technology for maintenance and refurbishment.
• Options: integrated thermal management, heaters, upgraded sealing and customized enclosures/front panels.

Integration & form factors
Plug-and-play modules are offered in standardized form factors to simplify integration: Ax: A5, A5+, A4+; Bx: Bx1, Bx2 and rack/blind-mate variants BxR1, BxR2. Front-panel choices include LCD, bargraph, handle, on/off button and combinations.
