These tests below only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Bottom Line
These cells appear identical to the LG H30 samples I received earlier this year but they did not meet LG’s 3000mAh minimum capacity rating. The two cells I tested delivered 2946mAh and 2947mAh at 600mA (0.2C) down to 2.5V.
This cell is a decent performer but the Samsung 30T is a MUCH better choice at high current levels, delivering about 30% more energy down to 3.2V at 30A. The Samsung 40T will also outperform it at up to about 20A-25A.
I am ESTIMATING this Vapcell’s ratings to be 30A continuous and 2900mAh. LG lists a 35A “max” discharge rating for the H30 but I believe that to be a temperature limited rating. LG lists a max cell surface operating temperature of 75°C and the two cells I had reached 74°C and 75°C at 30A. The “fast discharge” rating in the datasheet is 30A.
Two cells were donated for the purposes of testing by 18650batterystore (18650 Battery Store | 18650 Lithium Ion Batteries, Chargers and Wraps). Thank you!

Performance Specs
- DC Internal Resistance = 14.0mOhms (milliohms) average for the two cells.
- Total energy delivered down to 3.2V at 10A continuous = 9.0Wh (Watt-hours) average.
- Total energy delivered down to 3.2V at 20A continuous = 7.5Wh (Watt-hours) average.
- Total energy delivered down to 3.2V at 30A continuous = 5.6Wh (Watt-hours) average.
