Li-Ion rechargeable batteries
Li-Ion batteries have several advantages over Ni-MH batteries. The energy density is at least 40% higher compared with other good quality Ni-MH cells (compare Lupine Li-Ion battery 13,8 Ah with 8,2 Ah of the Ni-MH execution) at a distinctly lower weight. The self-discharge of maximum 15% in one year is extremely low - Ni-MH: 15% in the first week! Li-Ion batteries have a better voltage condition under high strain (e.g. when using 2x 25 Watt) and being cold (down to -40° C) Cause of the low weight, high capacity and no memory effect the Li-Ion battery is the first choice for serious riders.
The main disadvantages however are the higher costs as well as the necessary finish of the Li-Ion battery sets they must be absolutely waterproof. Therefore all our batteries are sealed 3-fold and are tested with 2,5 bar under-pressure. They also need a special protection circuit the so called PCB. |
