ETC 120Ah 3.2V Grade A LiFePO4 Prismatic Battery Cell – Low Profile 170mm Height – 6,000+ Cycles for Golf Carts, RVs & Marine Retrofits

ETC 120Ah: The Compact Powerhouse

The ETC 120Ah LiFePO4 Cell is defined by its unique dimensions, offering a specialized solution for mobile energy storage. With a height of just 170.6mm, it stands as the go-to choice for engineers and DIY enthusiasts who need to maximize capacity in battery compartments where standard 200mm+ prismatic cells simply will not fit.

🚀 Why Choose the ETC 120Ah?

  • ⚡ Perfect Fit for Golf Carts: Many lead-acid battery trays in golf carts are designed for shorter heights. The ETC 120Ah fits comfortably under the seat, and its 240A pulse discharge capability ensures it can deliver the immediate torque needed for quick acceleration.

  • ⚡ Long-Term Durability (6000+ Cycles): Despite its compact size, this cell does not compromise on service life. Rated for ≥ 6,000 cycles, it will outlast multiple sets of traditional lead-acid batteries, providing reliable, maintenance-free power for over a decade.

  • ⚡ Space-Saving for RVs: In camper van conversions, every inch matters. The low profile allows these cells to be installed in shallow compartments or under-seat storage areas, maximizing the living space in your mobile home.


🤝 Why Partner with DLCPO?

  • Genuine Grade A Authenticity: We source our cells directly from Wuhu Tianyi (ETC). DLCPO verifies the dimensions and electrical specs (Internal Resistance ≤0.40 mΩ) to ensure you receive the high-performance low-profile cells you expect.

  • 🎯 Complete Assembly Kits: We provide a Free Sorting Service to match your cells by voltage and impedance. We also supply the specific busbars and nuts required for these terminals to make your DIY build easier and more secure.

  • 🌐 Hassle-Free Global Shipping: Shipping lithium batteries internationally can be complex. Our DDP (Delivered Duty Paid) service to the USA, Europe, and Brazil covers all dangerous goods fees and customs duties, delivering your power solution straight to your door.

❓ Q:What is the difference between this 120Ah and the 135Ah model?
💡 A:

Both share the exact same physical dimensions (173.9 x 47.8 x 170.6mm). The 120Ah model has slightly less capacity but is often more cost-effective for budget-conscious projects while maintaining the same low-profile advantage and high pulse capability.

💡 A:

You would need 16 cells connected in series (16S) to create a high-performance 51.2V nominal battery pack. This is the standard, modern replacement for traditional 48V lead-acid systems, offering much longer range and lighter weight.

💡 A:

No. The 240A rating is for pulse discharge (up to 120 seconds), typical of a motor starting or climbing a hill. For continuous use, we recommend staying around 0.5C to 1C (60A-120A) to prevent overheating and maximize the cell’s lifespan. 🚀

Applications

  1. Golf Cart Upgrades: 170mm height fits existing lead-acid trays perfectly. 240A pulse handles hill climbing and starts.
  2. Camper Van Conversions: Low profile fits easily under swivel seats or in shallow false floors.
  3. Solar Storage: 6000+ cycles ensure long-term ROI for small off-grid cabins.
  4. Portable Power: Lightweight (2.85kg) and compact, ideal for 1kWh+ portable power stations.

Warnings & Cautions

  1. Avoid overheat in any circumstances. Don’t modify or disassemble the battery. It will be dangerous, and may cause ignition, heating, leakage or explosion.
  2. Don’t put cells in overheat circumstances or disposed in fire ,don’t put cells under the sunshine.
  3. Don’t short-circuit positive(+) and negative(-) terminals. Keep away from metal or other conductive materials. Jumbling the batteries of direct contact with positive(+) and negative(-) terminals or other conductive materials may cause short-circuit and may even cause fire and explosion.
  4. Don’t reverse the positive (+) and negative (-) terminals.
  5. Don’t put cells in water or other conductive liquids or let cells absorb a moisture.
  6. Don’t impact cells excessively.
  7. Don’t solder the battery directly. Excessive heating may cause deformation of the battery components such as the gasket, which may lead to the battery swelling, leakage, explosion, or ignition.
  8. Don’t use abnormal cell which has damages by shipping stress, drop, short or something else, and which gives off electrolyte odor.
  9. Don’t contact cans directly or with other conductive materials during the using process.
  10. Keep away form static circumstances during storage and using.
  11. Don’t use cells together with other one-shot batteries and secondary batteries. Don’t use cells together with different packages, types and brands.
  12. Stop using and process the cells accordingly when the following circumstances happened:getting hot sharply, smelling, changing colors, deformation or others.
  13. If there is leaked electrolyte from batteries, please scrub it away with fresh water to avoid any skin discomfort.

14.Notice: Low Profile (170.6mm Height). Check dimensions carefully. Pulse discharge rated 240A (120s); use appropriate busbars.
