The high-drain Samsung cell is a new entry in the market, notable for its ability to handle high currents with a low resistance of 11.67mR. Its discharge capability is comparable to the Samsung 40T series 3 cell, while offering 20% more capacity.

 

Our independent tests conducted with the Pulsar 3+ WiFi tester showed that at a load of 20A, the cell reaches a temperature of 53°C, generating a capacity above 5000mAh with minimal voltage drops. The test was performed on a cell charged to 4.2V and concluded at 2.5V. Further studies indicated that at a load of 25A, the cell does not perform sufficiently well. Although the manufacturer allows operation up to 80°C, optimal performance is achieved at temperatures up to 65°C. In the case of packs, the continuous current for a single cell should not exceed 22A. For higher currents, it is recommended to implement temperature control and disconnect the BMS in case of cell overheating. We recommend a safety limit of 80°C for a single cell and a maximum of 70°C for cells connected in a pack.
