One of the most important components of your Electric Bike is the battery. To prolong the life of your battery, and thus ensuring the Electric Bike performs to its optimum efficiency, diligent and purposeful care/maintenance must be done throughout the life span of the Electric Bike. The major difference between a regular and an electric bike, is provided below:

Regular Bikes – No battery is provided; the user is required to generate power to move the bike, by the use of the pedals.

Electric Bikes – They make use of batteries, and the user can select the amount of power required. Since the user can determine the amount of power, electric bikes can also be used as a regular bike, if no power is selected.

All bikes manufactured by DJ Bikes, have the option of regulating the amount of power from Level 1 to Level 5. The bikes will travel at 20% of the speed limit at Level 1 and 100% of the speed limit at Level 5. If you select the Level to 0, no power will be supplied to the pedals, therefore at Level 0, the bikes functions like a regular bike.

All Electric Bikes manufactured by DJ Bikes come with Lithium-ion batteries. They are preferred to other batteries, as they are rechargeable. The other advantages include:

  • Low maintenance, as compared to lead acid batteries, where water levels have to be checked regularly
  • They have a longer lifespan, which reduces the total cost of your Electric Bike
  • It is easier and faster to charge. The maximum charging period for the batteries provided with all bikes manufactured by DJ Bikes is 6 hours.
  • They are lighter in weight when compared to other same sized rechargeable batteries

The question now arises, what can be done to improve the efficiency and longevity of lithium-ion batteries. What are the necessary steps required to get optimum performance of an Electric Bike battery?

Charging

It is advisable to charge your Electric Bike’s battery immediately you receive the package; however, it is highly recommended you stop charging the battery immediately the battery is full (100%). If you continue to charge the battery when the maximum battery level has been attained, please note this leads to over-charging at elevated temperatures, and may result in internal lithium metal plating accelerated by a lasting loss in capacity. In lame man’s language, it causes irreparable damage to your battery.

Re-charging

It is not advisable to allow the capacity of your battery drain off completely, i.e. 0%, before recharging (always avoid full discharges). It is highly recommended you recharge your battery, when the battery level is between 20% and 30%. When charging your battery for the first time, it is OK to reach the maximum battery level (100%), however, it is highly recommended you avoid charging to the maximum capacity on subsequent occasions. As far as it is possible, always avoid fast charging or high loads.

At temperatures below 0oC, it is advisable not to charge your battery. This causes metal plating at the battery anode, and can make the battery volatile and dangerous because of the generated heat.

Storage

For an elongated battery life, it is recommended batteries are stored at 40% battery level at a cool temperature. The advisable range of temperature storage is between 5oC or 20oC. This is because lithium-ion batteries do not like high nor low temperatures. Temperatures above 20oC decrease the battery life. It is also not advisable to leave the batteries unused for an extended period of time. Therefore, charge at least once every six months to a 50% capacity and store separately from the Electric Bike. Since 4oC corresponds to the temperature of a refrigerator, you might be tempted to store your battery in a fridge. Wait! Don’t! The reason being a refrigerator is damp, and this can cause the rust to the battery parts.

Operating conditions

When operating your Electric bike, the advisable range of battery level between 30% and 80%

Handling guidelines

  • Do not attempt to dismantle, deform or create holes
  • Fire or water should not be used to dispose a lithium ion battery. Always check with the local regulatory authorities if you want to dispose or recycle. Do not dump batteries in the local dump or landfills
  • Always keep far from the reach of children
  • Do not touch any leaking fluids on your battery
  • Do not rub your eyes, should there be any eye contact with fluid. Instead, lift upper and lower lids, and use water to wash eyes carefully and thoroughly for at least 20 mins, at least until there is no indication of the fluid. Then seek medical help immediately
  • Do not use batteries that have been damaged

In summary, the lithium ion batteries (especially the ones that come with the bikes manufactured by DJ Bikes) are superb, and are designed for longevity. However, its performance and efficiency depend on the maintainability and usage by the user.

All batteries that come with bikes manufactured by DJ Bikes come with a Hazmat Safety (UN38.3) and UL certification, which have passed all quality assurance and control product tests. They are also shipped under the best practices and standards.
