RJ TECH: Next-Gen Sodium Batteries Dual use for Truck

At RJ TECH, we pioneer next-generation 24V Sodium-ion Dual-Purpose Batteries that seamlessly unite high-2500CCA sub-zero engine cranking with true deep-cycle auxiliary storage. 

Built for commercial fleets, our drop-in solution replaces unreliable lead-acid and fragile LiFePO4 packs—eliminating stranded-vehicle jump starts, handling temperatures down to -40°C, powering overnight parking AC for 10,000+ cycles, and dramatically lowering TCO

RJ TECH 24V Sodium ion Truck Batteries FAQ 

1: What is a 24V Sodium-ion Dual-Purpose Battery, and how does it combine both high-CCA cranking and deep-cycle storage?

Answer: A 24V Sodium-ion (Na-ion) Dual-Purpose Battery is an all-in-one commercial power solution designed to handle two contrasting demands: High-CCA Engine Cranking and Deep-Cycle Auxiliary Energy Storage. Utilizing high-rate Na-ion chemistry, a single battery pack delivers massive pulse discharge currents (1500A–2500A CCA) to cold-start heavy 13L–16L diesel engines while simultaneously providing over 10,000+ deep-discharge cycles (100% DOD) to power 24V parking air conditioners, refrigerators, and cabin electronics for 8–12 hours uninterrupted.

2: Can a single 24V Na-ion dual battery truly replace both standard lead-acid starter batteries and auxiliary parking AC batteries?

Answer: Yes, Our 24V Na-ion dual battery eliminates the need for two separate battery banks. Its advanced electrochemistry supports 10-30C high-rate cranking alongside true deep-cycle storage, acting as a direct drop-in replacement that saves chassis mounting space, reduces vehicle weight, and eliminates dual-system wiring complexity.

3: How does the high-CCA cranking performance of Na-ion dual batteries perform in sub-zero climates down to -40 ℃?

Answer: Unlike conventional AGM or LiFePO4 batteries that suffer severe power drop-offs in the freeze, Na-ion chemistry maintains ultra-low internal resistance at extreme sub-zero temperatures. At -20℃, our battery retains over >95% usable capacity, and at -40℃, it still outputs up to 2500A+ CCA to instantly spark frozen heavy-duty diesel engines without requiring built-in heating elements or external jump-starter boosters.

4: How does the Smart BMS manage deep-cycle parking AC loads while guaranteeing cranking power for the engine?

Answer: Our custom Dual-Function BMS features built-in Cranking Reserve Logic. When the truck is parked and running auxiliary deep-cycle loads (parking HVAC, appliances), the BMS continuously tracks the battery’s State of Charge (SoC). If the battery level drops to 15%–20%,  the BMS automatically disconnects auxiliary loads, strictly reserving the remaining energy exclusively for high-CCA engine ignition so the driver is never stranded.

5: What is the cycle life of a 24V Na-ion dual-purpose battery under daily deep-cycle parking AC usage?

Answer: Engineered for commercial longevity, our 24V Na-ion cells deliver over 10,000+ full charge/discharge cycles at 100% DOD (Depth of Discharge). Compared to standard AGM or lead-acid starter batteries—which degrade after just 300–500 shallow cycles when forced to run auxiliary loads—Na-ion provides 10-15 years of reliable service life, dramatically lowering total cost of ownership (TCO) for commercial fleet managers.

6: How fast can a 24V Na-ion dual battery be recharged from the truck’s alternator between rest stops?

Answer: Sodium-ion batteries feature exceptionally high charge acceptance rates (1C -5C continuous fast charging). While driving between logistics stops, the truck's standard 24V alternator can fully recharge a depleted 200Ah–314Ah dual battery pack in 1.5 to 2.5 hours. This fast-recharge capability ensures that your auxiliary deep-cycle capacity is fully replenished before the next overnight parking stop.

7: Is a 24V Na-ion dual battery safer than lead-acid batteries under high-vibration truck chassis conditions?

Answer: Yes. Na-ion chemistry exhibits superior thermal and structural stability with a thermal runaway threshold exceeding 260℃ and zero risk of metallic dendrite formation during sub-zero high-current cranking. Built inside heavy-duty IP65 waterproof aluminum or steel enclosures with high-shock absorption cell holders, our dual battery packs easily withstand harsh chassis mounting conditions and extreme road vibration.

8: How does zero-volt storage capability benefit seasonal truck storage and long-distance shipping?

Answer: Unlike lead acid batteries, which suffer permanent electrode degradation and copper dissolution if deeply over-discharged below critical voltages, Sodium-ion cells can be safely discharged down to 0 Volts (0V Storage) without structural or chemical damage. This allows long-distance overseas transport without hazardous material shipping restrictions and prevents battery "bricking" during prolonged seasonal truck idling.

9: Which capacity (Ah) dual-purpose Na-ion battery is right for our fleet or aftermarket business?

Answer:

• 24V 100Ah–300Ah (1200A–1800A CCA): Ideal direct drop-in replacement for standard 2x 12V lead-acid double boxes; designed for regional haulers needing instant sub-zero cranking plus 4–6 hours of rest-stop cooling.

• 24V 300Ah–942Ah (1800A–2500A CCA ): Our most popular commercial choice for long-haul sleeper cabs, providing 8–12 hours of overnight parking AC along with massive high-rate cranking reserves.

10: Do you support OEM/ODM manufacturing, custom BMS communication protocols, and global B2B distribution?

Answer: Yes. As a direct Sodium-ion battery factory, we provide complete OEM/ODM customization services for commercial vehicle upfitters, fleet operators, and global battery distributors. We offer custom enclosure dimensions, private labeling, CANbus / RS485 communication protocols (compatible with major parking ACs and telematics), and full international certifications (UN38.3, CE, MSDS, IEC).
