LG MJ1 INR18650 – 3.635V 3500mAh Li-ion Battery Cell (Up to 10A)
The LG INR18650 MJ1 is a high-capacity 18650 lithium-ion battery cell designed for reliable energy delivery in battery packs, portable power systems, and professional electronics. With a 3500mAh nominal capacity and a 10A max discharge rating, it is a proven option where runtime and consistency matter.
Why choose LG MJ1 (INR18650)?
- High capacity – 3500mAh nominal for long runtime in energy-focused builds
- Solid current handling – up to 10A max discharge for demanding loads
- Stable electrical characteristics – designed for consistent performance across use cases
- Pack-ready format – widely used 18650 size for battery packs and integration
- Low impedance – initial AC impedance ≤ 40mΩ (at 1kHz, per standard test)
How it works
The MJ1 is a rechargeable Li-ion 18650 cell with a standard 4.2V charge profile. For best results in professional use, follow standard CC/CV charging guidelines and integrate the cell into systems with appropriate protection and balancing (especially in multi-cell packs).
- Standard charge: 0.5C (1700mA) to 4.2V, cut-off 50mA
- Max charge current: 1.0C (3400mA)
- Discharge cut-off (end voltage): 2.5V
Safe integration notes
- Unprotected cell (no built-in PCB) – requires an external protection/BMS solution in packs
- Use only with compatible Li-ion chargers and correct charging parameters
- Avoid short circuit, mechanical damage, and exposure to heat
- Do not mix cells of different age, model, or state of health in the same pack
Important: This is a bare 18650 cell intended for controlled applications. For consumer single-cell use, choose a protected cell if your device does not include protection.
Setup recommendations (B2B / pack building)
- Use matched cells (same batch where possible) for multi-cell packs
- Implement a quality BMS for overcharge/over-discharge and balancing
- Design for thermal management and proper cell spacing
- Verify mechanical fit: 18650 dimensions Ø18.4 × 65.0 mm (max Ø18.5, max height 65.2)
