Lithium Battery Information

Battery

The lithium battery has a much higher energy density when compared with older technologies such as lead-acid. This means that the lithium battery is much lighter for the same amount of stored electricity. This means less weight on the bike which has many benefits, including more range for the same capacity, better hill climbing for the same power and a bike that is easier to manoeuvre.

The lithium battery is fitted with a battery management system (BMS) which actively monitors the battery. If any of the cells get too low in voltage, it can cut the power and prevent the cell from becoming over-discharged which can cause irreversible damage. The BMS is also active during the charging of the battery and performs a similar function which prevents the cells from receiving too much charge. The BMS is also able to even out the charge between cells with what is known as “balancing” the batteries. This typically occurs at the end of the charging cycle.

Battery Charging

The battery pack is supplied partially charged. To ensure full battery pack capacity, completely charge the battery pack in the charger before using for the first time. The battery pack can be recharged at any time on its own or on the bike without shortening the lifespan. Interrupting the charging process does not damage the battery pack. The batteries should only be charged when battery temperature is between 0°C and 40°C. Do not connect the battery pack to the charger until it has reached the allowable charging temperature.

At lower temperatures the charging time becomes longer and battery capacity is used less efficiently thus reducing the range of the battery. When charging at low temperatures we advise you to charge the battery separately in a warmer room. Do this by removing the battery from the bike. Use only the charger provided with your electric bike or an identical original Dillenger charger. Only this charger is matched to the lithium-ion battery pack used in your ebike.

Remove the charger included with the bike from its packaging and connect the mains plug to a mains socket. Connect the charger to the battery. For safe charging the charger must be placed on a suitable surface; the substrate must be dry and non-flammable. When you plug the charger into the battery, the light will show red. This means that the battery is charging. Once the battery is charged this light will change to green. Once charged, pull the charger plug out of the mains socket to save power. You can recharge the battery after every trip. This means you will always be ready to use the electric system.

Battery Care

Take care to ensure that the battery does not get too hot. Battery aging increases sharply with temperatures above 40 °C. Being placed directly in the sun’s rays can cause a battery to heat up considerably. Take care to ensure you don’t leave the battery in a hot car and park your bike in the shade during bike rides. If you cannot avoid the heat, make sure you don’t charge the battery at the same time.

A fully charged battery ages at an even higher rate at high temperatures than a partially charged one.

If you ride constantly using maximum motor power, your motor will constantly need a higher current. Higher currents cause the battery to age faster.

You can also increase the service life of your battery by using the assistance judiciously. Cycle using a low assistance setting. Lower discharge current draws will save your battery.

When not using the battery pack for a longer period, charge it to approx. 60 %.

When the battery pack is stored discharged (empty) for longer periods, it can become damaged despite the low self-discharging and the battery capacity may be strongly reduced. It is not recommended to have the battery pack connected permanently to the charger.
