Why LG M29?
- Branded quality at a good price — LG is one of the world’s largest cylindrical cell manufacturers. The M29 delivers consistent, predictable performance that cheap Chinese cells can’t guarantee.
- Better than EVE 29V and Samsung 29E — superior chemical stability, better durability under intensive use, lower internal resistance.
- 10A pulse discharge — handles short bursts significantly above the 6A continuous rating.
- Light weight at 48g — makes it easy to design compact, lightweight battery packs.
Applications
- Electric bikes (e-bike) — cost-effective 36V or 48V packs with good capacity
- Battery regeneration — drop-in replacement for worn cells in existing packs
- Lighting systems — flashlights, bike lights, emergency lighting
- DIY power banks — custom portable USB battery builds
- Small energy storage — off-grid and backup power projects
⚠️ Note: The LG M29 has a 6A continuous discharge rating. If you need higher current (above 10–15A), consider the Samsung 30Q or Samsung 25R. For maximum capacity, see the Samsung 35E.
This cell has no built-in PCM/PCB protection circuit. Use it in systems with an external BMS protecting against overcharge (>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?
The Samsung 35E has higher capacity (3500mAh vs 2900mAh) and higher continuous current (8A vs 6A), but costs more. The LG M29 is the better value choice when you don’t need maximum capacity.
Is the LG M29 suitable for an e-bike?
Yes — it’s a popular cell for building cost-effective e-bike packs at 36V and 48V. With 6A continuous discharge it handles motors up to approximately 400–500W.
Is LG M29 better than EVE 29V?
Yes — the LG M29 offers better parameter stability and durability under intensive use compared to EVE 29V or Samsung 29E at a similar price.
How do I charge the LG M29?
Use a CC/CV charger with a cutoff voltage of 4.2V and a charge current up to 2.75A. Standard charging current is 1.375A.
