Imalent 18650 3000mAh MRB-18P30 (Blue-black)

Official specifications:

Brand: Imalent
Type: Battery
Battery: 18650
Battery Type: Lithium-ion
Head Type: Button Top
Rechargeable: Yes
Protected: Yes
Voltage(V): 3.7V
Charge Current: 0.5A
Max. Charge Current: 1A
Max. Discharge Current: 15A

This is a battery with good capacity and good current capability.

The discharge curves tracks nicely, the battery can handle 10A and gets a bit hot at 15A.
20A is too much and the protection circuit disables the discharge.

The overload protection disables the batteries here.

Because I only test up to 15A in this test I did not trip the overload protection.

Conclusion

The battery quality is good for this battery, but as usual the protection will reduce the high current performance.
