A large LiFePO4 cell that can handle very high current.

The two cells tracks nicely. My test only goes to 30A and the cell has no problems with that.

At 30A the cell do not get very warm.

Here I calculate the internal resistance by turning 1A on/off during a full discharge.
Conclusion
The cell looks good, it has the rated capacity, and can deliver a lot of current at a stable voltage, but as always with LiFePO4 the voltage and capacity is lower than regular LiIon.
Notes and links
The batteries was supplied by Vapcell for review.

Thanks HKJ very much. Smile

The temperature rise of 30A discharge is very small, which means that it can discharge with larger current.

I want to make a comparison about A123 26650 M1B 2500mah and this vapcell battery, but I can’t find A123. Could you add it in?

Thanks

I have the data, I will see when I can get it published.

The ANR26650M1-B was reviewed by Henrik long ago, tested on his old station without fully independent cell voltage monitoring. I say this because of the July 2012 review date, not because I know it for sure so better wait for Henrik's word:

 

 

Both cells close in performance, but this newer one may have an edge.

You are right Thumbs Up ,can you get many M1b in your country?
