I came across These. it says continous discharge rate is 10A, but then in its description it say “this pack can only discharge at around 0.2C (700 mA) continuously / safely, with 3.5 A fast drain.”
so which one is it? 10A or 700mA?
@fsycdt Welcome to the RobotShop Community. This pack is based on LG’s MJI 18650 battery. The maximum burst discharge current is 10A, whereas the standard continuous discharge is 0.2C, or ~0.7A. There are quite a few articles and videos which put this to the test.
Use this battery for its high capacity vs. weight, but not if you need a high discharge rate.

Thanks @cbenson. But it says 10A is continuous discharge and 20A is the burst discharge (under specification). So I guess that is an error and the actual continuous discharge is 0.7A and burst discharge is 10A?
Very difficult to find LG’s official page for this battery, not sure why.
I attached what seems to be the datasheet.LG-18650.pdf (343.3 KB)
Looking up several review sites as well, the consensus seems to be:
- Model: INR18650-MJ1
- Size: 18650
- Style: Flat Top
- Chemistry: INR
- Nominal Capacity: 3500mAh
- Normal charging current: 0.5A constant
- Standard discharge: 0.2C (680mA)
- Continuous Discharge Rating: 10A
- Nominal Voltage: 3.6v
- Protected: No
- Rechargeable: Yes
- Approximate Dimensions: 18.30mm x 65.10mm
- Approximate Weight: 49g
