The Lithium EB ECO 70.4V 100Ah battery is a high-capacity lithium-ion energy storage system designed for demanding applications like commercial EVs, solar storage, or industrial equipment. Operating at a nominal 70.4V (equivalent to 22 cells in series at 3.2V each), it delivers 7.04kWh of energy with optimized cycle life through advanced LiFePO4 chemistry and integrated battery management systems (BMS) for thermal regulation and cell balancing.

What applications suit the EB ECO 70.4V 100Ah?
This battery excels in high-torque electric vehicles and off-grid energy storage. Its 70.4V configuration supports sustained 5-7kW power demands, ideal for forklifts, aerial work platforms, or solar microgrids. Pro Tip: Pair with 72V-rated inverters for solar systems—voltage drop under load won’t trigger premature low-voltage cutoffs.
Beyond basic voltage compatibility, the EB ECO’s 100Ah capacity enables 6–8 hours of continuous operation in industrial equipment. For example, a 70.4V pack running a 3kW pallet jack provides ~2.3 hours of runtime. Thermal resilience up to 60°C makes it suitable for warehouse environments where lead-acid batteries degrade rapidly. But how do you prevent voltage sag during peak loads? The BMS dynamically allocates current across parallel cell groups, maintaining stability even at 95% depth of discharge.

How does its BMS enhance safety?
The proprietary BMS enables active balancing and fault isolation. It monitors individual cell voltages (±0.5mV accuracy) and temperatures, disconnecting faulty cells within 50ms of anomalies. This prevents cascading failures common in budget lithium batteries.
Traditional passive balancing wastes excess energy as heat, but the EB ECO uses bidirectional DC-DC converters to redistribute charge between cells. During charging, this cuts balance times by 40% compared to resistor-based systems. A real-world analogy? Think of it as having traffic cops at every cell intersection, rerouting energy instead of blocking lanes. The BMS also logs 30+ parameters—from cycle counts to historical max temperatures—accessible via CAN bus for predictive maintenance.

FAQs
Yes, but verify charger compatibility—lead-acid profiles overcharge lithium. Use LiFePO4-specific chargers with 70.4V CV phase at 3.65V/cell.
What’s the lifespan in solar storage applications?
15+ years with daily cycling, assuming 80% DoD and ambient temps below 35°C. Partial cycling (30% DoD) extends this to 20+ years.
