Allied Battery, the leading name in lithium golf car battery innovation, debuts their new Relay BMS + Smart System model with the introduction of the RS Series.
Unlike other golf car lithium batteries that often over‑discharge in storage, drift out of balance, and require users to lift the seat for access, the Allied Relay Smart System (RS) combines Allied’s proven core features with industry‑leading innovation to create a seamless, connected system. The result is lower risk for dealers and superior experience for end users.
What’s New in the RS Series
The RS Series builds on Allied’s proven lithium solution while introducing several key upgrades:
- Relay HiPerformance BMS with BuiltIn Solenoid: At the core of the RS Series is Allied’s new Hi-Performance Relay BMS. The next generation of Allied Batteries includes a fully integrated internal Solenoid that pairs seamlessly with the hi-performance BMS. Key advantages include:
- Integrated Solenoid – Built directly into the BMS, eliminating the need for bulky external components.
- Cleaner Install – Internal design means fewer connections, cleaner installs, and greater longterm reliability for dealers.
- Storage Disconnect – Fully cuts off discharge from outside components during storage, preventing over-discharge.
- No Parasitic Drain – Eliminates slow battery drain from accessories when not in use, preserving charge for months.
- Extended Remote Power Button: The Allied RS includes a Dual Power system that allows the placement of a 2nd power button outside of the battery tray, allowing user to power the battery on or off without ever lifting the seat. Designed to mount neatly under the driver’s feet near the charging port.
- Enhanced Internal Structure: Reinforced mounting frame, designed for maximum vibration resistance, keep internal structure secure in demanding golf car conditions. Built for the rugged demands of golf car use.
- Sealed & Protected Design: Vertical mount gasket system keeps out moisture and dust, while a builtin water draining lip prevents buildup around critical areas for all weather use.

RS Series — Advancing Allied’s Most Trusted Features:
- Grade A – EV Cells: Allied uses true Grade A cells, unlike others who have switched to cheaper storage cells that are not designed for EV use. This shortcut taken by others causes reduced range and shorter battery life.
- Bluetooth Mobile App: Gain easy access to State-of-Charge, cell voltage, cycles and much more.
Includes a robust OEM dashboard to allow off-site maintenance and troubleshooting, ensuring efficient and timely fixes for optimal customer experience.
- Innovative Sleep Mode: Our sleep mode eliminates the risk of over-discharge if a customer leaves headlights or other accessories on. When paired with the Allied Relay Hi-Performance BMS the paired system will disconnect ALL draw from motor, controller and accessories, eliminating the risk for over-discharge completely and protecting the customer’s investment.
Sleep mode ensures that your customer’s battery remains protected and ready for action when needed.
CAN bus and RS485: Allied Batteries include CAN bus and RS485 protocols natively, allowing seamless integration with various controllers and display screens.

Allied Battery has developed an upgraded State-of-Charge meter with speedometer to work perfectly with ICON cars and includes all required harnesses.
- Integrated 2A Active Balancer: Most golf car lithium batteries rely on passive MOSFET balancing that only works during charging often taking weeks to correct cell drift, if at all. Allied’s integrated 2AMP Active Balancer works during both charging and discharging, keeping every cell balanced and ready for use.
- 80X Faster – Corrects imbalances in hours, not weeks.
- Works in Real Time – Balances cells while driving and charging.
- Ensures a True Full Charge – Every cell reaches the same voltage for consistent range and performance.
- Extends Battery Life – Prevents capacity loss and cell stress.
- Thick Steel Case: The structural integrity of the Allied Battery casing is designed to prevent any potential for dents or punctures. The thick steel walls not only ensure physical resilience but also promote optimal heat dissipation, contributing to the battery’s overall efficiency and performance.
- Fire Suppression Technology (FST): In the event of excessive heat or a fire near the battery, Allied’s proprietary FST discharges a chemical mixture, enveloping the interior of the battery. This process eliminates oxygen within the battery case to provide a shield from external threats.
- Built for Real Golf Car Use: Unlike lighter, stripped‑down designs that sacrifice protective components to save space, every RS battery is built with the same ruggedness Allied is known for. Thicker cases, robust lock‑downs, airflow‑optimized layouts, and fully insulated key components are standard in every model.
- For Dealers and End Users Alike: Dealers will appreciate the RS Series for its reliability, ease of installation, and advanced safety protections, reducing callbacks and warranty issues. End users will enjoy practical conveniences like the Remote Power Button, advanced Sleep Mode, as well as peace of mind with the builtin fire suppression module.
- Free Shipping On All Batteries: Allied offers free shipping on ALL orders. No LTL, lift gate, residential or other up charges – you pay for the top-rated Allied product – they take care of the rest.

This applies to any quantity, whether you are stocking up for the season at your dealership, or just need a single battery. Enjoy the convenience and cost savings of free shipping to your business or directly to your customer.
- National Sales & Support Teams: Allied has a dedicated in-house support team as well as a national sales team to support and work directly with the dealer network. No more texting and emailing oversees companies and waiting for answers. Dealers expect timely and quality support for which Allied is proud to provide.
Allied is at the forefront of the lithium industry’s growth, offering the best lithium solutions that fit both user and dealer needs. Join the many dealers who have already experienced the reliability and power of Allied Battery.
