18650 Battery 2600mah 3.7V 21700 Battery Electric Bicycle/Scooter
This is probably the most important thing to consider when selecting your high rate of discharge 18650 battery. You need to know how much continuous current the device you are trying to power requires before choosing your device’s high rate battery. If you choose a battery with a current rating less than what you need, you will notice the battery overheating as it is working beyond its ability to keep up.
Our high rate discharge 18650 battery is also given a C rating in terms of burst, which is how quickly the battery can discharge for a short time.

FQA:
1.What is so special about 18650 battery?
“18650 lithium battery”. The 18650 battery has a voltage of 3.6v and has between 2600mAh and 3500mAh (mili-amp-hours). (Osborne, 2019) These batteries are used in flashlights, laptops, electronics and even some electric cars because of their reliability, long run-times, and ability to be recharged hundreds of times over.
2. What is a 18650 lithium battery?
“18650 lithium battery”. The 18650 battery is a model of rechargeable battery of lithium of 3.7 volts. These rechargeable batteries are very similar to AA batteries but a little bit bigger size. These 18650 batteries also calling Li-ion batteries. The advantage of these rechargeable batteries is there are very lightweight batteries.
3. How long does a 18650 lithium battery last?
Most modern 18650 batteries have a typical cycle life of 300 - 500 (charge, discharge cycles). When in high-amp or high-drain situations, this can decrease substantially to 200 cycles. If you go over the maximum discharge current limit (A) you can decrease the cycle life all the way down to 50 cycles.
4. What battery can I use instead of 18650?
21700 – were designed to be a larger and higher capacity replacement for 18650 batteries. Like the 18650, the 21700 has a nominal voltage of 3.6/3.7V. The 21700 was designed to replace the 18650 in EV battery packs.
