Test/review of Vapcell INR18650 3000mAh S30 (Red) 2020

Vapcell INR18650 3000mAh S30 (Red) 2020







Official specifications:

  • Nominal Capacity: 3000mAh

  • Min Capacity: 2900mAH

  • Nominal Voltage: 3.6V

  • Discharge End Voltage: 2.5V

  • Standard Charging Current: 2A

  • Charging Voltage: 4.20 +/-0.05V

  • Max. Continuous Discharging Current (Vapcell specification): 25A

  • Dimensions: 65.00mm (L) x 18.3 mm (D)

  • Weight: 50.0g max



This is a fairly high current 18650 cell from Vapcellwith good capacity.










The two cells tracks nicely and hold voltage fairly well.






















Conclusion

This is a fairly good cell with both capacity and high current.

Thanks for the review and all your valuable work.

You mention in the First line that this is a KeepPower cell? Must br a Typo.

Most cells seem to have over rated capacity.This being 2800mAh instead of claimed 3000mAh is a bit more over rated…maybe a VTC5D rewrap?

It is and I have corrected it (At the current time I am doing a lot of Keeppower cells).

The typical cell rating requires a specific temperature for charge and discharge and charge may be with a lower termination current than I use and is usually also to a lower voltage than I do. All this together can explain some difference.

It may be a rewrap or a Chinese cell, some China factories are getting very good at making LiIon batteries.

It hasn’t discharged to 2.5V

The battery capacity is about 2950mah
This is not vtc5d

Thanks HKJ :+1:

Can you tell us the battery inside? It seems to perform slightly better than the VTC6 at 15-20 amps but is just a little lower in capacity.

Custom battery, we should be the only one with this battery at present :slight_smile:

This would be great for high power soda can lights.

This is a discharge rate enhanced Samsung 30Q; the shape of the discharge curves match, its top too. Versus a 30Q its internal resistance is lower, while its capacity is a little bit lower. This allows the cell to meet a 20A continuous discharge rating without exceeding 80°C (at 25°C ambient).
