Bistable Relay

The Super B Nomia Bistable Relay is rated up to 260A (12VDC) and is designed to work with single Super B Nomia Lithium Batteries, offering high-performance switching for demanding applications. Capable of high-peak currents, this Bistable Relay allows you to remotely control your battery circuit with precision, reducing manual intervention and improving system reliability in motorsport, marine or mobile energy installations.

Why Choose the Super B Nomia Bistable Relay

The Super B Nomia Bistable Relay provides an electrically controlled and resettable ON / OFF switch control to protect, manage and optimise your lithium battery setup. It uses a bistable mechanism (which holds state without continuous coil power), drawing minimal standby current. It can switch high-current loads when required, with peak current capacity up to 1500A.

Designed specifically for use with the Super B Nomia range (12V100Ah, 12V160Ah, 12V210Ah), the Bistable Relay ensures your battery system can be controlled efficiently and safely. With the included 1m cable, installation is straightforward and suited to high-demand situations where high switch capacity and reliability are essential. Continuous current is limited to 190A at 85°C / 185°F.

3-Year Warranty

The Super B products come with a 3-year manufacturer warranty and support from Aim Shop’s experienced technical team for your peace of mind. Whether you're building a custom energy setup or upgrading your vehicle's power system, Super B provides batteries that have been engineered and tested against the harshest of environments to ensure high-performance for years to come.

Trusted by adventurers and sailors worldwide, Super B Energy Batteries are renowned for their reliability, compact size and seamless integration with modern systems. Take a look at some of the testimonials from people who have used Super B for their own projects.

Feel The Breeze Super B Testimonial for sailboat

Feel The Breeze

"We have 8 lithium iron phosphate batteries (LiFePO4) at the core of our sailing yacht, a massive upgrade from the old lead-acid. The simplicity of installation, quality, and durability made this a no-brainer!" - Feel The Breeze

Stepsover World Tour Super B Testimonial for 4x4 MAN truck

Stepsover World Tour

"Lithium batteries are the best solution for an overland truck like ours. Our truck is equipped with a useful domotic system that controls everything inside the truck, from the ventilation system all the way to the water pressure inside the plumbing system. This is really useful in order to prevent damage on the road and to manage every function of the interior with just a click on our tablet. We successfully integrated the new Super B lithium batteries in our truck and now we really feel more independent." - Stepsover World Tour

Sailing Fair Isle Super B Testimonial for sailboat

Sailing Fair Isle

"These batteries are a game-changer for living off grid, and we know, from talking to our fellow cruisers, that we are not the only ones making this change to lithium. Super B are the best in the business. As we continue our journey around the world, we feel safe in the knowledge that these may be the last set of batteries we ever need to install." - Sailing Fair Isle

How do you download the "Be In Charge" software & app?

Super B provides a Be In Charge Software tool, which can be used to read out the internal BMS system. The software uses a CAN to USB converter to connect to the communication interface. The software is capable of reading out the actual status, like battery/cell voltages and temperature, but also statistical information. Be In Charge software can also be used to update the installed firmware of the Li-ion battery. The Be In Charge software and hardware are not part of the Li-ion battery scope of delivery. Super B also provides a Be In Charge App for mobile devices such as Android and iOS. The app can be found in the Google Play Store or Apple App Store.
