E-BIKE BATTERY FAQ
QUESTIONS ABOUT E-BIKE BATTERIES
What is the range I can achieve with an e-bike battery ?
This depends on the exact specs of the battery you have. Our smallest e-bike battery is 48v 10.5ah. When riding Medium level power assist with a person that weighs an average of 80kg your average range for this battery will be 50km per full charge. Increase the weight and/or the level of PAS (power/pedal assist) and the result will be less range. Range from your battery also depends on two other main factors – Firstly the steepness and type of the terrain you are riding on ( off road tends to use more due to loose gravel and debris). Secondly the way in which a person rides with gears. Being in the right gear at the right time. For example: shifting into the right low gear when riding up a very steep hill and correct high gear when riding on light hills or flat terrain. It also helps to be in a high gear when pulling off. Similar to that of driving a manual car.You would pull off in first gear not second of third gear.
How long does will my e-bike battery last before I need to replace it?
The short answer is 4-5 years. However this depends on how much you ride your e-bike. Your battery will give you between 800-1000 life cycles ( full charges ) before you need to replace it. Here is an example – if you ride 4 times per week and charge your battery 4 times . Multiply 4 x 4 gives you a total of 16 life cycles per month. Multiply 16 x 12 gives you a total 192 life cycles per year. Multiply 192 x 5 gives you a total of 960 life cycles. This is a calculation based on average usage because sometimes you may ride only 2 or 3 times per week or month or perhaps 5 or 6 times per week. However other factors will effect the health of your battery and how many life cycles you can achieve. The better you care for your battery the longer it will last. Battery care is answered in the next few questions.
How do I best take care of my battery to optimize life cycles ?
It is best to not run your battery down lower than 15% when riding. When your battery shows a level of 15% charge left thats the time to charge it full again. A couple of times now and then of running the battery down lower than 15% will most likely not damage cells but by repetitively running your battery down to zero power it may cause irreversible damage to the Samsung cells.
Avoid dropping your battery , one damaged cell from a knock will effect the others negatively.
How do I best store my battery when not riding my e-bike ?
Lithium Batteries do not like long periods of exposure to heat or cold and moisture. When you are not riding your e-bike it is best to keep your battery in a fairly cool & dry place. You may also leave the battery on your electric bike. This is fine as long as it is not sitting in a heated garage or store room.
However if you plan to not ride your e-bike for a period of 2 weeks or more it is best to remove it from your e-bike.
If you leave it on your e-bike even if everything is powered off , the energy from the battery is slowly drained.
What is the best way to charge an e-bike lithium battery?
Our smart chargers stops charging your battery once it is full. However since we sometimes have power surges and to prevent the charger from over heating, the best way is to turn the charger off once the battery charge indicator turns green indicating the battery is fully charged.
Unlike lead acid batteries that can be trickle-charged, e-bike battery chargers are best turned off when the battery is full.
Don’t I lose a life cycle each time I charge my battery ?
No. Chilled Squirrel’s Samsung batteries contain a BMS (battery management system) that cleverly avoids using a full life cycle each time you charge unless the battery is near to empty. For example if your battery is 50% full and you charge it the BMS will calculate a half life cycle instead of a full life cycle thereby ensuring you do not waste life cycles and giving you the freedom to charge your battery full at anytime you would prefer to leave on your ride on a full charge.
