LG INR18650-M29 2900 mAh 6A - 18650 cell

The LG INR18650-M29 is a reliable 18650 cell from a trusted manufacturer — good capacity of 2900mAh, stable continuous current of 6A, and low internal resistance of ~22mΩ. New, original LG cell, unused, from current production.

An ideal choice for building and regenerating battery packs, electric bicycle batteries, lighting systems, and DIY projects — where reliability and repeatable parameters are important at a good price.

Technical Data

Why LG M29?

• Branded manufacturer at a good price — LG is one of the largest manufacturers of cylindrical cells in the world. The M29 ensures quality and repeatable parameters, which cheap Chinese cells do not guarantee.
• Better than EVE 29V and Samsung 29E — higher chemical stability, better durability under intensive use, lower internal resistance.
• 10A pulse current — for short-term loads, the cell can handle significantly higher current than 6A continuous.
• Low weight 48g — lightweight cell facilitates the design of compact and light packs.

Applications

• Electric bicycles (e-bike) — economical 36V or 48V pack with good capacity
• Battery regeneration — replacement for worn-out cells in existing packs
• Lighting systems — flashlights, bicycle lights, emergency lighting
• DIY power banks — custom portable USB chargers
• Small energy storage systems — off-grid and backup power projects

⚠️ Note: LG M29 is a cell with a continuous current of 6A. If you need higher current (above 10–15A), consider Samsung 30Q or Samsung 25R. If maximum capacity is the priority — check out Samsung 35E.

The cell does not have a built-in PCM/PCB system. Use it in systems with an external BMS that protects against overcharging (>4.2V), over-discharge, and short circuits.

Frequently Asked Questions

Is this a new cell?

Yes — new, unused cells from current LG production.

What is the difference between LG M29 and Samsung 35E?

Samsung 35E has a higher capacity (3500mAh vs 2900mAh) and a higher continuous current (8A vs 6A), but costs more. The LG M29 is a cheaper option where you don't need maximum capacity.

Is LG M29 suitable for an electric bicycle?

Yes — it's a popular cell for building economical 36V and 48V e-bike packs. With a continuous current of 6A, it will work well in bicycles with power up to approx. 400–500W.

Is LG M29 better than EVE 29V?

Yes — LG M29 offers higher parameter stability and better durability under intensive use than EVE 29V or Samsung 29E at a similar price.

How to charge LG M29?

CC/CV charger with a final voltage of 4.2V and a current of up to 2.75A. The standard charging current is 1.375A.
