"8. How long time does the battery of my Helkama pedelec last?Electrically assisted Helkama pedelecs are equipped with Panasonic motors and batteries
. Panasonic is a world leading supplier of motor systems for electrically assisted bicycles. The endurance of the battery depends on many things: temperature, terrain, the weight of the driver, amount of acceleration and the used level of assistance. The Panasonic-system has three different levels of assistance: 50%, 100% and 150%. When the stronger assistance is used, the battery will become empty sooner. The motor is controlling the need for assistance with a moment controller and the bigger the force on the pedals, the more the motor is assisting.
A fully charged battery is capable of assisting up to 80 km, but depending on the environment, the level of assistance, etc. the distance can be a lot shorter. The manufacturer guarantees 500 charging cycles from empty to fully charged or up to 1.000 charging cycles from half empty to fully charged.
