The RS (Relay Smart System) is Allied Battery's 2025-generation model. It adds three capabilities not found in the standard commercial battery: an integrated internal solenoid built directly into the Relay BMS, which removes the need for a separate external solenoid; a dash-mounted remote power button that allows the battery to be powered on or off without lifting the seat; and a 2-amp integrated active balancer that operates during both charging and driving, correcting cell imbalances 80 times faster than the passive system used in the standard model. Both versions include Grade A EV cells, the Bluetooth app, CAN Bus and RS485 protocols, dynamic sleep mode, and the 8-year manufacturer warranty.

The RS 48V 105Ah is compatible with EZGO (TXT, RXV, S4), Club Car (DS, Precedent, Tempo, Onward), Yamaha, ICON, AdvancedEV, Polaris, and Bad Boy Buggy in 48V configurations. Physical dimensions are 18.5 inches long by 11.5 inches wide by 10.1 inches tall. Club Car Precedent models from 2004 to 2008 may require minor battery tray modification before installation. Contact us before ordering to confirm fit for your specific year and model.

Most owners complete the full conversion from lead-acid to lithium in under 30 minutes using basic hand tools, a socket set, wrenches, and a screwdriver. No controller reprogramming is required. Because the RS integrates the solenoid into the BMS, there is no external solenoid to mount or wire. The kit includes an installation guide. Allied Battery also operates a network of authorized dealers who can perform the installation if you prefer to have it done professionally. Contact us if you have more questions.

A standard 2-passenger, non-lifted cart on flat terrain with a controller rated up to 250 amps typically achieves 30 to 45 miles per charge. A modified, lifted cart with a controller rated up to 400 amps typically achieves 20 to 35 miles. Highly modified 4- to 6-passenger carts with controllers up to 600 amps are outside the rated capacity of the 105Ah, the 168Ah option is appropriate for those carts. All figures are estimates and vary based on terrain, speed, passenger and cargo weight, and accessory load.

Yes. LiFePO4 lithium iron phosphate chemistry does not have a memory effect. The battery can be charged at any state of charge without reducing its capacity or service life. You can plug in after a short ride, between rounds of golf, or any time the cart is parked near a power outlet. Lead-acid batteries can be damaged by partial charging cycles. The RS is not affected by partial charging.

A full charge using the included 15-amp onboard lithium charger takes approximately 2 to 4 hours. The charger shuts off automatically when the battery reaches full capacity. A 30-amp charger, available separately, can reduce charging time. Lead-acid batteries in the same cart configuration typically require 8 to 10 hours for a full charge cycle.

Yes. In sleep mode, this battery loses 1 to 3 percent of its charge per month. Before leaving for an extended period, press the power button to activate sleep mode. The BMS will disconnect all draw from the motor, controller, and accessories automatically. The battery can safely remain in storage for up to 12 months under these conditions. Lead-acid batteries lose up to 33 percent of their charge per month when idle and can sustain permanent damage during extended storage without regular charging.

Yes. The RS carries an IP66 ingress protection rating. IP66 indicates the enclosure is fully sealed against dust and protected against powerful water jets from any direction. Normal rain, course conditions, and cart washing will not affect the enclosure.

Yes. The RS BMS supports 350 amps peak discharge sustained for up to 10 seconds and 600 amps instantaneous peak for up to 3 seconds. Golf cart batteries with a 200-amp peak limit can trigger BMS protective shutdowns when paired with high-performance aftermarket controllers. The RS is designed to operate with Navitas, Teekon, and similar high-amperage controllers without triggering protective shutdowns under normal use.

Yes. A 12V step-down DC-to-DC converter is required for any 12V accessories, including headlights, horn, radio, or other 12V devices. Do not connect 12V accessories directly to the 48V battery terminals, as this will damage the accessories and may damage the battery. The converter is available as a separate add-on item in our store.

The battery must not be charged in temperatures below 32 degrees F (0 degrees C). Charging below freezing can cause permanent cell damage. The battery can be driven and discharged in temperatures as low as 15 degrees F (-9 degrees C). If your cart is stored in an unheated space during winter months, allow the battery to warm to above-freezing temperature before beginning a charge cycle.

Yes. The RS 105Ah supports a maximum of 2 modules connected in parallel, producing a combined capacity of 210Ah. This is the only approved configuration for parallel connection. Do not connect more than 2 units in parallel, and do not connect the RS in series with other battery types or models.

No. The 8-year manufacturer warranty applies to the original purchaser only and is non-transferable. To activate the warranty, the battery must be registered at AlliedLithium.com within 30 days of the purchase date. Batteries not registered within this period are not eligible for warranty coverage.

The Allied Battery app is free and available for iOS and Android. It connects via Bluetooth and displays: overall pack voltage, individual cell voltages, remaining charge percentage, estimated discharge time remaining, estimated time to full charge, current amp draw, cell temperature, and lifetime power cycle count. The app is not required for normal operation of the battery. It provides diagnostic information for the owner and allows Allied Battery's support team to diagnose issues remotely when needed.

The Fire Arrestor (FST) is a passive safety feature built into the RS battery case. If the battery is exposed to an extreme external heat source or an external fire, the system releases a proprietary chemical mixture inside the sealed case. The process removes oxygen from within the enclosure to protect the internal cell assembly from the external heat source. The system activates automatically and requires no action from the user.

Yes. The RS is compatible with the EZGO RXV regenerative braking system. No additional resistor coil is required. Some lithium batteries on the market require an additional resistor coil for regenerative braking compatibility, the RS does not.

No. The RS is a fully sealed battery requiring no scheduled maintenance. There is no water to add, no acid to check, no corrosion to clean, and no equalization cycles required. The BMS manages cell-level protection automatically throughout the life of the battery. The only action required after purchase is registering the battery at AlliedLithium.com within 30 days to activate the 8-year warranty.
