Product ID: LCEV Lithium-Ion Batteries for Electric Vehicles (EV) Lithium-Ion (Li-Ion) batteries for electric vehicles (EV), ranging from cars, motorcycles, bicycles, and scooters.

Specifications: Eletric Characteristics Rated voltage: 3.7V Recommended charging current: 0.3C Cycle Life 500 cycles for 80+% retention capacity if charge/discharge at 0.2C. Operating temperatures Discharge temp.: -40 ~ 60°C Charging temp.: 0 ~ 45°C Storage temp.: -20 ~ 45°C Enclosure Material: Stainless Steel Recomended charge method: Charge around 0.3CA (> 0.5CA may shorten cycle life) when voltage is between 3.0V and 4.2V. Charge at 4.2V +/- 0.05V until current < 0.01CA. If voltage is below 1.5V, don't charge, i.e. dispense, the battery. If voltage is between 1.5V and 3.0V, charge slowly, e.g. 0.01CA. Recomended discharge method: Discharge under rated current when voltage is between 4.2V and 3.0V. Don't discharge if voltage is below 3.0V. Don't discharge between rated current and max current for more than 12 seconds. Specific Energy Density 110~120WH/Kg Features: Custom design for special dimensions welcome. FAQ1: Q: Do you have protection circuit board and charger that can work well with the batteries? A: We are designing the protection circuit board and charger right now. We can provide samples in June, 2004. FAQ2: Q: What's 1.5CA discharge? A: If the capacity is 11Ah per cell, 1.5CA = 1.5 * 11 * A = 16.5A.
