Lithium Block Modules - 5P to 10P

Lithium Block™ is a family of compact, modular 18650-based battery blocks built for real integration work—fast to assemble, predictable under load, and easy to scale. Each block is a parallel “P” unit you can stack into strings for your target voltage. Choose Energy or Power chemistry, in 5P, 6P, 7P, 8P, 9P, or 10P. What it is Air-cooled lithium-ion block with slim, repeatable geometry for tight packaging and dense arrays. Rugged glass-filled UL94-V0 ABS enclosure that helps mitigate propagation and protects the stack. GEN2 option adds connectorized cell voltage/temperature on a flex, resettable sense fusing, and busbar mounting inserts to speed assembly and service. Performance at a glance Capacity per block (approx.): 17.5 Ah (5P) to 35 Ah (10P), variant dependent. Energy per block (approx.): ~52 Wh to ~125 Wh, variant dependent. Power Module peak current: up to 210 A (see datasheet for continuous vs peak and thermal derating). Designed for consistent internal resistance and stable thermal behavior so packs stay predictable as you scale. Energy vs Power (how to choose) Energy: longest runtime and lower heat at moderate currents. Best when life and efficiency matter more than bursts. Plan for headroom; add parallel rather than running cells at their limit. Power: higher discharge capability for short, repeatable bursts and aggressive duty cycles. Use when transient demand and acceleration dominate. Validate thermal path and duty cycle. Where it fits Robotics/AGV/AMR and portable instruments that need reliable, all-shift operation. Prototyping and low-volume production in aerospace, defense, specialty EV, and industrial systems. Compliance Housing materials meet UL94-V0. Modules are UN38.3 certificated. Bottom line Pick the P-count for capacity, pick Energy or Power for your current envelope, then scale the array. Lithium Block gives you a clean, serviceable building unit that moves from prototype to production without changing the footprint. | Gen2 Lithium Block™ — Modular Wire-Bonded Battery Modules for Scalable Systems The Gen2 Lithium Block™ from CIE Solutions is a compact, air-cooled lithium-ion battery module engineered for modular energy systems requiring high current, high reliability, and flexible integration.
