The CALB L173F230B is the premier choice for users who find standard 280Ah cells too large or heavy but still demand high-capacity performance. Known as the Reliable Workhorse, this Grade A prismatic cell offers a perfect balance of energy density and physical footprint, making it ideal for 12V (4S) or 24V (8S) battery systems in camper vans and off-grid solar generators.
Extreme Cold Weather Performance: Unlike budget LFP cells that shut down at -10°C, the CALB L173F230B continues to provide reliable power down to -30°C, ensuring your system stays active in harsh winter conditions.
Exceptional Cycle Life: Rated for more than 4,000 cycles, this cell delivers over 10 years of consistent value in typical solar storage applications.
Precision Engineering Specs: Features a standard width of 173.93 plus or minus 0.15 mm, a total height of 217.9 plus or minus 0.4 mm, and a slim thickness of 53.72 plus or minus 0.15 mm.
Industrial Compression Standards: To maintain peak performance, the engineering datasheet specifies a pre-tightening pressure of 300 plus or minus 20 kgf (at 20 percent SOC), ensuring structural integrity over its entire lifespan.
Fresh Production Only: We strictly avoid the performance degradation found in aged inventory. Every CALB L173F230B cell is freshly manufactured to order, ensuring 100 percent chemical activity and verifiable Grade A quality.
Grade A Traceability: We provide only Brand New cells with original, intact QR codes, guaranteeing that the performance you receive matches the technical datasheet precisely.
Global DDP Logistics: DLCPO manages the entire supply chain, including international freight, customs clearance, and import duties. We deliver your cells directly to your door with zero hidden fees.
Professional Cell Matching: Every set is rigorously tested and matched for Voltage and Internal Resistance (IR) at our facility before shipping, ensuring your battery bank is perfectly balanced from day one.
A: The CALB L173F230B has a precision-engineered body size: length is 173.93 plus or minus 0.15 mm, thickness is 53.72 plus or minus 0.15 mm, and the total height including terminals is 217.9 plus or minus 0.4 mm. The terminal center-to-center distance is 123 plus or minus 0.3 mm.
A: Yes. For optimal structural health and cycle life, the industrial specification recommends a pre-tightening pressure of 300 plus or minus 20 kgf during pack assembly. This compression helps prevent cell expansion and maintains consistent internal contact.
A: The CALB L173F230B is specifically designed for high performance in cold climates and is rated to provide power down to -30°C. While charging in extreme cold still requires careful management, this model offers much wider discharge availability than standard lithium iron phosphate cells.
