Li-ion (Lithium-Ion) batteries have the following advantages in comparison with other older battery technologies : Longer lifetime = more cycles ! Lighter in weight : 3 x lighter than lead-acid batteries Better for the environment than lead-acid : ECO friendly The complete battery capacity is available (no memory-effect) Flat discharge characteristic, nominal tension is kept regardless the state of charg Intermediate charging is no problem ! Battery Usage (1)Before using the battery, you should read the battery and charger specifications carefully in case that the battery and charger are damaged due to unreasonable usage.

( 5 ) When putting the batteries in series, if the voltage between the two electrodes of the battery pack is over 36V, the safety voltage of human beings, you are forbidden to touch the battery?s two electrodes with your body. Warnings Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by. Do not use or leave the battery near a heat source as fire or heater.
