1. WHICH BATTERY SHOULD I CHOOSE?
This really depends on the application and can be a hard question. The bigger (and more expensive) the battery is the longer your range....also the harder it is to fit in your bike. (space is an ebikers most valuable commodity. Do your research if this is your first ebike kit to make sure you are getting the right battery for your needs.
2. WHAT CELLS ARE YOUR BATTERY PACKS MADE UP OF?
All our packs are made up of authentic Grade A battery cells. We use only premium cells to make battery with best BMS and best ingiredients.
3. WHAT IS A BMS
Battery management system. BMS is used to supervise battery by measure its voltage, temperature, current and SOC (State Of Charge), give out alarm under wrong circumstance, cut off electric power link in severe situation in order to protect battery and make its life longer. BMS can balance energy among batteries to make them more identical and expand its discharge cycle.
4. HOW MANY VOLTS SHOULD I CHOOSE?
Depending on your controller. All 48v controllers can handle either 48v or 52v packs. If you have a 36 volt controller however you will need to upgrade it before you can run a 48 or 52v pack.
5. HOW MANY AMPS DO I NEED?
Also depending on your ebike controller. However in the case of amps its not bad to have too many. The controller will only take what it needs.
6. HOW MANY AMP HOURS DO I NEED?
The more amp hours your battery has the more range you have. Also the larger and heavier (and more expensive) your pack will be. (read this story on calculating range)
Lithium batteries are presently the most commonly used energy storage devices on electric bike, electric scooter, golf car, mobile phones, laptops, digital cameras and other electric devices. Learning how to maintain lithium batteries can not only prolong battery lifetime but also protect your device from potential damage.
1. Charge new batteries. It's not necessary to charge over 12 hours when first used. When a device powered by batteries is purchased, sellers will usually tell us the batteries must first be charged 12 hours before using. Actually, this is unnecessary. Unlike common Ni-CD or Ni-MH batteries, most lithium ion batteries are activated before leaving the factory. Due to their low self-discharge, it’s unnecessary to charge lithium ion batteries for such a long time when new. Lithium ion batteries are ready for use when the charger indicates so, and they will reach their best capacity after 3 or 5 cycles.
2. Use appropriate chargers. Many people take great care with their electronic gadgets, but often neglect the consequences of bad chargers on their lithium ion batteries. When choosing a charger, the original charger is the best choice. If that's unavailable, a high quality charger that has an overcharge protection function, or a brand name charger will do. A low quality battery charger can lead to shorter run times, premature battery failure, or even fire or explosion.
3. Avoid frequently over charging. Over charging with a low quality charger may let the battery's interior rise to a high temperature, which is bad for the lithium ion battery and charger. Thus, simply fully charging is good enough - overcharging will make your lithium battery into a little bomb if overcharge protection function is missing.
4. Avoid touching metal contacts. All batteries' contacts need to be kept clean for best performance. When carrying batteries around, do not let the contacts touch metal objects such as keys; this could cause a short circuit, damaging the battery or potentially resulting in a fire or an explosion.
5. Avoid using often in high or low temperature environments. Lithium ion batteries have optimal working and storage temperatures. If they're continually used in extreme temperature environments, this will negatively affect battery use time and useful cycles.
