1.8 Amp-Hr Lithium Ion battery Micro-battery Cordura battery soft caseLi-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 percent 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 minus 40 degree 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 the 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.
