The CALB L148F88A is specifically engineered as the Cold Weather Specialist for industrial and motive applications where standard LFP batteries fail. With an industry-leading 174.5 Wh/kg energy density, this 88Ah cell provides significant weight savings compared to older 100Ah generation models while maintaining superior thermal stability.
Extreme Low-Temperature Operation: Features advanced electrolyte chemistry allowing for -30°C charging capability, eliminating the need for expensive heating pads in sub-zero environments.
Incredible Energy Efficiency: With an ultra-low internal resistance of just 0.3 mΩ, the CALB L148F88A minimizes heat generation during discharge, maximizing your systems run-time.
Precision Compact Design: Standing at a total height of 104.5 mm and a thickness of 52 mm, these cells allow for high-capacity pack integration in space-limited enclosures.
Grade A Quality Control: Sourced directly with original, intact QR codes to ensure full traceability and consistent performance across modular banks.
Strictly Fresh Production: We avoid the risks of aged stock by following a Produced to Order policy. Every CALB L148F88A cell is freshly manufactured to guarantee 100 percent chemical activity.
Bespoke Connection Hardware: Based on your technical requirements, we provide customized hardware including flexible busbars and nuts to ensure secure, low-resistance connections.
Global DDP Logistics: We simplify your procurement with Delivered Duty Paid (DDP) shipping options, handling all customs clearance and import taxes for a seamless door-to-door experience.
A: Known as the Cold Weather Specialist, the CALB L148F88A can be charged at temperatures as low as -30°C. This advanced capability makes it ideal for industrial robotics or off-grid storage in harsh winter climates where standard LiFePO4 cells cannot operate.
A: The cell features a width of 148 mm, a thickness of 52 mm, and a total height of 104.5 mm. For optimal structural stability and longevity, the engineering specification recommends a pre-tightening pressure of 300 plus or minus 20 kgf during pack assembly.
A: Yes. At 174.5 Wh/kg, the CALB L148N88A is significantly lighter than previous generations of 100Ah cells. This allows you to build a higher-capacity battery bank with less total weight, which is critical for mobile applications or electric vehicle conversions.
Product Overview:
The CALB L148F88A is a specialized wide-temperature LiFePO4 cell. Unlike standard LFP cells that stop working at freezing, this robust cell supports charging and discharging capabilities in extreme cold environments (down to -30°C).
