The CALB L135F72, famously known as the Slim Beast, is engineered for applications that demand extreme burst power from a compact footprint. While standard cells prioritize slow energy storage, the CALB L135F72 acts more like a supercapacitor, delivering massive current for high-load tasks without the bulk of larger 100Ah or 280Ah cells.
8C Pulse Discharge Power: This high-performance cell can deliver a staggering 576 Amps for 10 seconds. It is specifically built for heavy-duty acceleration and starting high-torque motors where other 72Ah cells would struggle.
Ultra-Slim Profile: At only 30.0 mm thick, the CALB L135F72 allows for creative installations in narrow gaps, making it a favorite for custom electric vehicle builds and space-limited industrial robotics.
Precision Industrial Specs: Features a width of 135.0 mm and a total height of 220.8 mm, providing a stable and standardized form factor for high-density modular pack integration.
Industrial-Grade Reliability: Built with CALB original automotive-grade standards, ensuring safety and thermal stability even under consistent high loads.
Freshly Produced (No Aged Stock): At DLCPO, we strictly avoid aged inventory. Every CALB L135F72 we supply is produced to order from the latest manufacturing batches, ensuring 100 percent chemical activity and full power performance.
Global DDP Logistics Solutions: To streamline your procurement, we offer DDP (Delivered Duty Paid) shipping. We manage the entire supply chain—including customs clearance and import duties—delivering your cells directly to your facility with zero hidden costs.
Bespoke Hardware Configuration: Based on your technical requirements, we can provide customized hardware, including flexible busbars and laser-welded terminal studs, for a secure, low-resistance connection in high-vibration environments.
A: The CALB L135F72 features a precision-engineered slim profile: width is 135.0 ± 1.0 mm, thickness is 30.0 ± 1.0 mm, and the total height including terminals is 220.8 ± 1.0 mm. The body height without terminals is 215.8 ± 1.0 mm.
A: An 8C discharge rate allows the CALB L135F72 to handle short-duration current bursts up to 576 Amps. This is ideal for applications like DIY EV acceleration, high-power engine starting, or industrial machinery that requires immediate, high-intensity energy delivery.
A: Yes. We specialize in DDP (Delivered Duty Paid) delivery. Upon request, we provide a quote that covers all international freight, insurance, and local import taxes. This “door-to-door” service ensures you receive your freshly produced cells at your location without dealing with complex customs procedures.
Product Overview:
The CALB L135F72 is a unique “High Power” prismatic cell. Despite its slim profile, it packs a punch with an incredible 8C discharge rating, making it one of the most powerful cells in its class.

Compact Powerhouse:
Car Audio: The 8C (576A) burst power eliminates headlight dimming and feeds hungry amplifiers.
Jump Starters: Capable of starting engines when built into a 12V 4S pack.
Tight Spaces: At only 29mm thick, these cells fit where standard brick batteries cannot (e.g., behind seats, in door panels).
Portable Power Packs: Lightweight (1.75kg) high-output power for drones or field equipment.
High Current Safety: When using near the 8C limit, ensure your busbars and cables are rated for 500A+.
Connection: Ensure solid contact. Loose connections at high current will generate dangerous heat.
BMS: Use a BMS that can handle high surge currents if using for starting/audio applications.
