125Actualización del mercado de celdas de batería Ah LiFePO₄: CALVO, VÍSPERA, y comparación de Lishen

With the growth of energy storage and electric vehicle markets, 125 Ah LiFePO₄ (LFP) cells have become key components. CALVO y VÍSPERA cells offer excellent performance, but due to supply constraints and production focused on large-scale orders, they are currently difficult to procure.

A diferencia de, Lishen 125 Ah cells are readily available and serve as a practical alternative. With dimensions of 200 × 33.2 × 173 mm, Lishen cells are similar to EVE, allowing existing battery pack designs to adapt without major layout changes.

Key Technical Comparison of 125 Ah LiFePO₄ Cells

In terms of size, peso, and performance, the three 125 Ah LiFePO₄ cells each have their strengths. Lishen and EVE cells are similar in length and slightly narrower than CALB, while CALB is thicker but shorter. All three cells weigh approximately 2.39–2.45 kg. EVE offers the lowest internal resistance (~0.40 mΩ), making it ideal for high-rate applications, whereas Lishen provides low resistance with stable performance, and CALB has slightly higher resistance but excellent consistency. Regarding cycle life, CALB and EVE last around 4000 ciclos, while Lishen provides about 3000 ciclos, suitable for general energy storage or light-duty applications. In terms of operating temperature and charge/discharge current, EVE supports the widest range, including short-term 3C pulses, while CALB and Lishen are stable at 1C standard charge/discharge, suitable for most ESS and auxiliary power systems.

Considering these differences, la physical dimensions of each cell are an important factor when designing battery packs:
