- Good quality Review by Szabolcs
-
Maximum current hasn't been tested, but the capacity is as described. The internal resistance is low (<12mohm (1khz)) they were equalized - exactly same voltage each. (Posted on 11-10-24)Rating - Strong player 50s Review by Marek

It is undoubtedly a strong player, I built a 20s 7p battery, i.e. about 35Ah, and loads of around 150Amperes do not make a big impression on these cells. They work great in stronger structures, and I know for sure that frequent momentary (30 sec) loads of around 20 amperes per cell do absolutely no harm to them. My discharge counter currently shows 97 and after connecting the battery to the EBC discharger, the capacity still oscillates around 34Ah. I recommend it because it is a really good piece of energy.

-
Usually capacity 5000mah is in place. Some orders came with less capacity (need to exactly discharge to 2.5v to get 5000mah). Each cell vary the internal resistance 10.5~12mOhms, so there is no consistency. I would like to get more stable capacity and resistance numbers from Samsung for not the cheapest price on market (Posted on 21-06-24)Rating - The batteries are very good Review by Petko
-
The batteries are very good and meet factory specifications. the internal resistance is 10.6 mΩ and the capacity is 5000 ma. (Posted on 17-01-24)Rating - Perfect Review by OLEG

Delivery is a little bit longer than expected but better is perfect. Thank you. (Posted on 23-12-23)Rating - Samsung INR21700-50S 5000 mAh – 35 A Review by Andreas

Vape on! (Posted on 15-09-23) - Puissantes, faible auto-décharge. Review by Philippe

J'ai utilisé dix de ces cellules pour construire une batterie à BMS la plus compacte possible pour placer dans un tube de vélo pliable afin d'alimenter un moteur central de 36 volts / 250w. Je ne pensais pas parcourir autant de km (+ de 50) avec aussi peu de cellules. Essai concluant.Rating
---------------------------------------------
I used ten of these cells to build the most compact BMS battery possible to place in a collapsible bicycle tube to power a 36 volt / 250w mid motor. I did not expect to travel so many km (+ 50) with so few cells. Conclusive test. (Posted on 28-12-22)

Take care
- Li-ion batteries can be dangerous when used wrong, short circuit or wrong usage can lead to fire or an explosion
- Do not put the battery in a charger or equipment with wrong terminals connected
- Never short cut the battery. Take care you don’t short cut it accidentally, do not put it in your pocked together with bunch of keys
- Do not disassemble or deform the battery. Dispose it if the battery is deformed
- Do not immerse in water
- Avoid excessive physical shock or vibration
- Do not expose to, dispose of the battery in fire
- Keep out of the reach of children
- Never use a modified or damaged charger
- Do not leave battery in charger over 12 hours
- Store the battery in a cool, dry and well-ventilated area
- Dispose of in accordance with local regulations
- Do not solder on these cells
