The two cells tracks fairly well and can easily deliver the rated 4A with only a small capacity drop.
Conclusion
This battery is one of the highest capacity 18500 I have seen to date (6-2020) and it can handle a fair amount of current, without being a high current cell.
Well, well well! Seesm like we have a new 18500 ready for the re more recent “shorty” lights we have
Thanks for the review HKJ! I feel like I will order a pair of these
Ehh… Just received 5pcs Vapcell ICR18500 2000mAh (Green)
The comparative charts do not diverge too much so I will not whine.
Anyway thanks for the review!
Great to have these 18500’s tested… Are these also the best 18500s in terms of ‘drain’, though “4A” is less than some 14500, but this 18500 is defintely higher capacity
I’m about to ask something that I’m reluctant to ask because it gives you so much extra work on top of the great job you are already doing.
Performance goes down as the temperature drops. For batteries used in bike lights specs around freezing may be a selling point.
The capacity at 0C/32F.
I have tested a few batteries at low temperature, but it is not something I will do on a regular basis. It requires a computer and other equipment in the kitchen with wires into the fridge.
I totally understand that!
That’s why I wrote I’m reluctant to ask/write/suggest.
I’m NOT asking for a review, proof, whatever but can you mention an estimate based on your knowledge?
Something like: “At 0C/32F, most cells have 30-40% less capacity than at room temp”
