EVE C40 3.2V 20Ah 40135 LiFePO4 Cylindrical Battery Cell

3C High-Discharge 40135 LiFePO4 Cylindrical Cell for E-Mobility & Power

When designing battery packs for e-bikes, portable power stations, or automated robotics, you need cells that can sustain high surge currents without voltage collapse. The EVE C40 20Ah LiFePO4 Cylindrical Cell delivers 64Wh of energy in a robust 40135 form factor, engineered for a verified 3C continuous discharge (60A per cell). Backed by EVE’s RD-C40-S01-LF specification, this cell guarantees 3,500 cycles even at an aggressive 90% Depth of Discharge (DoD). For Pakistani EV converters, DIY powerwall builders, and portable electronics manufacturers, the C40 provides the documented high-amperage reliability required to run motor controllers and heavy inductive loads safely.

Why Choose the EVE C40 40135 Cylinder?

1. Verified 3C (60A) Continuous Discharge

Many suppliers falsely market 20Ah cylindrical cells as “5C”. The official EVE RD-C40-S01-LF datasheet confirms a true 3C (60A) continuous discharge. In a 16S1P (51.2V) configuration, this pack can safely deliver 3,072W of continuous power. This provides the massive surge current required for e-bike hill climbs, portable power station inverter startups, and heavy-duty robotics without tripping the BMS or causing severe voltage sag.

2. 3,500 Cycles at an Aggressive 90% DoD

Most LFP cells are rated for 3,000 cycles at 80% DoD. The C40 is engineered to sustain 3,500 cycles at 90% DoD while retaining ≥70% of its initial capacity. This means you can safely use 18Ah of the cell’s 20Ah capacity every single day, maximizing the usable energy of your battery pack without prematurely aging the chemistry.

3. Ultra-Low ≤3 mΩ Internal Resistance

With an AC resistance of ≤3 mΩ, the C40 minimizes internal heat generation during high-amperage discharge. This thermal efficiency is critical for tightly packed cylindrical battery modules in e-bikes and power tools, where heat buildup can trigger thermal throttling.

“In the battery market, confusing pulse ratings with continuous ratings is a dangerous game. The EVE C40 is a verified 3C (60A) continuous cell, not a 5C cell. We publish the exact RD-C40-S01-LF datasheet specifications because professional pack builders need to know exactly what their BMS and busbars must handle. When you build traction packs, honesty in the C-rate is the only metric that matters.”

System Integration & High-Current Pack Building

At 60A per cell, your supporting hardware must be rated for real current.

• BMS Selection: For full 3C operation, ensure your BMS or contactor system is rated for the total pack current. For standard 12V/24V e-bike or solar setups, the JK Smart BMS (100A variant) provides excellent active balancing and over-current protection.
• Custom Pack Assembly: Need a turnkey 48V e-bike battery or a custom portable power station? Explore our Custom Battery Solutions Services, where Newon handles professional spot-welding, thick nickel strip sizing, and load testing.
• Compare Options: If you need a slightly smaller 15Ah 3C cell, view the EVE C33 15Ah. For large stationary home solar, view the EVE LF100LA 102Ah Prismatic.

EVE C40 FAQ

Is the EVE C40 a 5C high-drain cell?

No. According to EVE’s official RD-C40-S01-LF technical specification, the C40 supports a 3C maximum continuous discharge (60A). Claims of 5C continuous discharge for this specific model are incorrect and usually confuse peak pulse ratings with continuous thermal limits. Newon strictly adheres to the manufacturer’s continuous discharge datasheet.

What is the 40135 form factor?

The 40135 designation refers to the cell’s physical dimensions: approximately 40.5mm in diameter and 135.0mm in height. This large-format cylinder bridges the gap between standard 21700 cells and bulky prismatic blocks, offering excellent volumetric energy density for e-bike downtubes and portable power station shells.

Can I use these cells for a 48V e-bike battery?

Absolutely. A 16S (51.2V) configuration of C40 cells yields a 20Ah (1,024Wh) pack capable of delivering 60A continuous (over 3,000W). This is the ideal specification for 1000W to 2000W e-bike motor controllers.

How does the 90% DoD cycle life compare to standard cells?

Most standard LFP cells degrade rapidly if pushed past 80% DoD. The C40 is engineered to sustain 3,500 cycles at an aggressive 90% DoD, meaning you can safely use almost all of the battery’s rated capacity every single day without sacrificing its multi-year lifespan.

Disclaimer: Specifications are based on the manufacturer product page or supplier’s current technical datasheet for the stated model (RD-C40-S01-LF). Actual performance varies with production revision, cell age, temperature, charge/discharge rate, depth of discharge, compression, BMS settings and pack design. Cycle-life figures are laboratory results under specified conditions and are not a guarantee of service life. A loose cell is not a finished battery. A completed pack requires a compatible BMS, protection, fusing, insulation, mechanical support and a suitable charger.
