Test/review of Keeppower IMR18650 NH1831 3120mAh (Black) 2016
Keeppower IMR18650 NH1831 3120mAh (Black) 2016
Official specifications:
A high current and high capacity cell from Keeppower. There is no doubt this is a quality battery, the curves track perfectly and capacity is nearly constant with current. At high current the battery gets hot and I stopped the 30A test due to that. At 20A the cell gets rather hot, but it stayed just below 80°C At 30A discharge the temperature reached 86°C, but first after I stopped at 80°C. Conclusion This is a very good high current battery, but 30A will need a temperature cutout to stay safe. Notes and links The batteries was supplied by Keeppower for review. How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Compare to 18650 and other batteries
