While many LiFePO4 cells are built for slow, steady solar storage, the CALB L173F163A is built for action. Designed as a high-power solution, this 163Ah cell is the premier choice for EV battery pack upgrades (48V/72V/96V) and heavy-duty industrial power systems.
High Discharge Performance (3C): With a peak output of $489$ Amps, a simple 4-cell (12V) pack can deliver nearly $6000$ Watts of instantaneous power.
Ultra-Low Internal Resistance: The internal resistance of $0.2$–$0.5$ m$\Omega$ ensures minimal voltage sag under heavy load, providing “peppier” acceleration for electric vehicles.
Tier 1 Automotive Reliability: CALB is a Tier 1 supplier for major EV manufacturers, ensuring that every CALB L173F163A cell meets automotive-grade durability standards.
Ultra-Slim Profile: At only $36.36$ mm thick, these cells allow for high-density configurations in narrow battery compartments.
Freshly Produced (No Aged Stock): At DLCPO, we strictly follow a “Produced to Order” policy. Every CALB L173F163A cell is supplied from the newest production batches with 100% chemical activity and original, verifiable QR codes.
Bespoke Hardware Configuration: We don’t just provide generic parts. Based on your project, we customize the configuration of busbars, nuts, and laser-welded M6 studs to ensure a perfect, low-resistance fit for your pack design.
Global DDP Delivery: To simplify your international procurement, we offer DDP (Delivered Duty Paid) shipping options. We handle the entire supply chain—including customs and duties—delivering the CALB L173F163A directly to your door with zero hidden costs.
Matched Grade A Sets: Every order is rigorously tested and matched for Voltage and Internal Resistance (IR) at our facility to ensure your high-power system remains perfectly balanced.
A: The CALB L173F163A features a precision slim profile: length is $174.4 \pm 0.15$ mm, total height (including terminals) is $232 \pm 0.3$ mm, and thickness is $36.36$ mm. The terminal center-to-center distance is $116 \pm 0.3$ mm.
A: A 3C discharge rate means the CALB L173F163A can safely discharge at three times its capacity ($489$ Amps) for short durations. This provides the high torque and rapid acceleration required for EVs, boats, and heavy-duty machinery that standard storage cells cannot provide.
A: Yes. We configure connection kits based on your needs, typically including busbars, nuts, and insulation sheets. We can also provide cells with custom laser-welded studs to simplify your assembly and ensure maximum electrical conductivity.
