[size=+3]Vapcell INR21700 3100mAh (Purple)[/size]
Official specifications:
One of the new slightly larger batteries, this one with fairly low capacity, but very high current capability.
Good tracking, expect a small capacity difference. The batteries has nearly constant capacity op to 30A and the 35A rating looks very realistic.
The cells do not get too warm at 30A discharge current.
[size=+3]Conclusion[/size]
This is a good high current battery.
[size=+3]Notes and links[/size]
The batteries was supplied by Vapcell for review.
