Test/Review of MXJO IMR18350 700mAh (Yellow)

[size=+3]MXJO IMR18350 700mAh (Yellow)[/size]



Official specifications:

• Capacity: 700mAh
• Nominal Voltage: 3.7V
• Max. Continuous Discharge Current: 10.5A
• Max. Discharge Current: 14A
• Dimensions: 35.5*18.5MM (+/-0.05)mm
• Operating Discharge Temperature: -10 to 60 Degrees Celsius
• Standard Charge: CC/CV 0.5A, 4.20 ± 0.05 V
• Cycle Life: > 300 cycles
• Weight: 28g

This is a high current 18350 cell










The discharge curves looks good with the cell tracking nicely and nearly constant capacity. The 15A discharge was way above the capability of the cell.







The cells do not get too hot for this discharge current because the time is very short (Between 2 and 3 minutes).
The peak temperature registered is 40°C above ambient, this means around 65 to 70°C on the outside.















[size=+3]Conclusion[/size]

These cells has a good high current performance performance, but capacity is on the low side due to the high current ability.
It looks like a good cell.

What do you calculate the mAh capacity to be at 1.5 amps? I have no idea how to calculate it from graphs or chart due to my own ignorance.

According to the table it is 704mAh at 1A and 700mAh at 2A, a guess would be 702mAh

OK so as advertised no? I give them credit for giving a real world number even if their max current claims are exaggerated.

Bottom line is if people expect to run a constant 10 amps from any 18350 let alone 16340 they are kidding themselves. Even 3 amps is a stretch.

Impressive performance. I notice Mooch gave them a very low rating, but I guess that's down to not using proper test equipment, or not being paid to test and promote the results. I can't get a hold of these in UK.
