Heavy-duty cylindrical case with PTC protection and safety vent for high-capacity energy storage cells
The Cell Lab 32650 Cylinder Cell Case is a precision-engineered housing designed for large-format lithium-ion battery research and prototyping. Constructed from nickel-plated A3 steel, it provides exceptional corrosion resistance and mechanical durability. Each unit includes a pressure-release anti-explosive top cap, a PTC thermistor for over-temperature protection, and a nylon insulation O-ring for electrical isolation.
Ideal for EV battery modules, high-current energy storage, and advanced R&D, this casing ensures safe and reliable operation under demanding conditions. Its 32 mm outer diameter and 68 mm height make it compatible with standard 32650 cell dimensions, offering consistent performance for laboratory and pilot-scale cell assembly.
Accurate Fit for 32650 Format
Precisely machined with OD 32.0 mm, ID 31.5 mm, and height 68.0 mm to ensure perfect alignment during cell assembly.
Anti-Explosive Safety Cap
Integrated pressure relief vent opens automatically at 2.5 MPa to prevent hazardous overpressure conditions.
PTC Thermistor Protection
Built-in thermal switch interrupts current flow above 120 °C, reducing the risk of overheating and thermal runaway.
Durable Nickel-Plated Steel Shell
Made of corrosion-resistant A3 steel for mechanical stability and long service life in battery environments.
Integrated Nylon O-Ring
Provides secure electrical insulation between terminals to prevent short circuits during operation.

Q1: Are these cases compatible with standard 32650 jelly rolls?
Yes. They are dimensionally accurate for all standard 32650 cell cores and electrode windings.
Q2: Does each case include the safety cap and insulation ring?
Yes. Each set includes the cap, case body, and nylon O-ring pre-assembled.
Q3: What’s the function of the PTC thermistor?
It automatically limits current when temperature exceeds 120 °C, enhancing safety under short-circuit or overcharge conditions.
Q4: Can the cap be laser welded?
Yes. The nickel-plated surface supports reliable laser or spot welding during tab connection.
Q5: Is custom branding or packaging available?
Yes. OEM labelling and bulk order packaging can be provided upon request.
