Lithium Block™ GEN 1 Module
Lithium Block™ GEN1 — Proven, Modular 18650 Block (5P–10P)
Field-tested lithium-ion modules in scalable parallel counts for real-world builds. GEN1 combines energy-focused and power-focused cell options in a robust UL94-V0 glass-filled ABS housing, ready to stack into packs for portable, industrial, and light EV systems.
- 5P–10P variants
- ~17.5–35 Ah range*
- Up to 210 A peak (Power Module)
- UN38.3 & IEC 62133
Built for integration: slim geometry, serviceable housing, and repeatable dimensions for tight packaging.
Scalable architecture
Choose 5P–10P to right-size capacity and current for your pack. Slim housing fits constrained spaces.
Energy or power
Energy modules for runtime; Power Module for bursts up to 210 A peak* in the same footprint.
Safety-minded housing
UL94-V0 glass-filled ABS enclosure designed to help mitigate propagation and protect the stack.
Pick your module — 5P to 10P
Select a parallel count for capacity; choose the Power Module when peak discharge is critical.
Variant | Nominal Capacity | Energy (approx.) | Max Discharge (Power) | Use Case |
---|---|---|---|---|
5P | ~17.5 Ah | ~52 Wh | up to 210 A* | Compact energy / light bursts |
6P | ~21 Ah | ~63 Wh | up to 210 A* | Balanced energy vs. power |
7P | ~24.5 Ah | ~80 Wh | up to 210 A* | Higher runtime |
8P | ~28 Ah | ~100 Wh | up to 210 A* | Energy-leaning systems |
10P | ~35 Ah | ~125 Wh | up to 210 A* | Max runtime in same footprint |
*Peak current shown for the Power Module. Validate continuous vs. peak and thermal derating in your design.

GEN1 vs. GEN2 — which fits?
Choose GEN1 if you want…
- Proven module form factor with slim housing.
- Simple integration without connectorized cell telemetry.
- Lower BOM complexity for basic monitoring approaches.
Choose GEN2 if you need…
- Connectorized cell V/T on flex for tighter data fidelity.
- Resettable sense fusing and busbar mounting inserts.
- Faster, repeatable assembly from proto to production.
