Capacity from 1300mAh to 3500mAh, Max Discharge current from 3.6A to 32A

✓Temperature – A high rate of discharge 18650 battery will age at an accelerated rate below 0℃ or above 45℃. If you are running your high rate discharge 18650 batteries hot, this will certainly cause premature aging.

✓Charging and Discharging – To get the Max cycle life from your high rate discharge battery, we recommend keeping it within a range of 3.00V – 4.00V. This trip does take some effort as most batteries will discharge down to 2.75V before requiring a recharge and will fully charge up to 4.20V.
The logic behind this is when you push the cell to the extremes of its capabilities, it will put stress on the battery. In testing, batteries kept in this range will have double the life expectancy.

✓Charger – To get the most out of your high rate discharge 18650 batteries, you should always make sure your charging device automatically turns off when charging is complete. It is also recommended to remove the high rate discharge 18650 batteries from the charger once charging is completed as many chargers have a function to continually top off the battery to make sure it is always at max capacity. This constant topping off can stress a battery and cause it to age prematurely.

✓Charge Rate – There are chargers on the market capable of charging at 4A or even 6A. While this can be very convenient, keep in mind rapid charging can accelerate the aging process as these speeds put added stress on the battery cell. A healthy range to charge your high rate discharge 18650 batteries at is anywhere between 0.1A and 3A.

☞: We avoid using any pulse ratings as there are far too many factors to consider when pulsing a battery such as a pulse length, time at rest between pulses, and battery temperature to accurately compare two batteries. For these reasons, we use the CDR rating(Current Discharge Rate) which is the current discharge rate at which the battery can be continuously discharged safely without overheating or damaging the cell.
