Pros
- Fast delivery in 3-4 days, very high quality packaging (bag, carton box, paper general box, individual paper boxes for each battery). Corresponds to the declared technical characteristics in terms of size, weight and capacity, in terms of internal resistance it is slightly worse than declared. High-quality and branded (see barcode), neatly designed (heat shrinkage is even, contacts are clean and smooth), medium current (10 Amperes) batteries; the popular 18650 form factor (it fits into any device through adapter tubes), the declared capacity is practically within the tolerance of + -5% (one battery is better than 3343 mAh, the second is slightly worse than 3230 mAh), good internal resistance (about 40 mOhm), they behave normally under a load of 10 Amperes (the capacity decreases slightly, by about 400 mAh, the temperature rises, but somewhere around 58 degrees Celsius, which is also not bad)
Cons
- High price (for this money on Aliexpress you can buy not 2, but 3 of these batteries), the variation in capacity between two batteries is about 100-110 mAh and the capacity itself should be closer to 3500 mAh, I would like to have a stable current at the output for this money 15-20 amps, not 10 amps. In principle, you can take light green Litokala with a capacity of 3400 mAh, it will be cheaper and approximately the same in terms of output characteristics!
