AG9 battery.Series connection of 18650 lithium batteries

release time:2023-10-11 Hits: Popular:AG11 battery

　　By connecting multiple 18650 lithium batteries in series, the voltage value of the combined batteries can be obtained, but the current remains unchanged. The principle of connecting lithium batteries in series is that as the voltage increases, the current remains unchanged. The high voltage caused by battery series connection also has some serious problems. If the 18650 lithium battery pack is connected in series to work, if one of the 18650 lithium batteries fails, it will affect the voltage drop of the entire battery pack, shorten the usage time sharply, and the broken 18650 lithium battery pack has a large internal resistance. If it is still forced to work at this time, it will cause a significant decrease in the output voltage of the entire battery pack. The basic parameter requirements for series batteries are not too high, but the higher the consistency of the battery, the better. The main reason is that there is a decay process in battery use, and inconsistent parameters can lead to an accelerated decay rate of a certain battery section. If one section of the series circuit is damaged, the entire battery will be scrapped. However, fortunately, this effect is not very strong and the impact is not significant. As long as different types and capacities of batteries are not connected in series, It's basically no big deal.

　　By combining multiple 18650 lithium batteries in parallel, you can obtain a larger battery capacity, which is more professional. Parallel connection of lithium batteries results in constant voltage and increased capacity. How many lithium batteries are connected in parallel, and the total capacity is the sum of the capacities of all single lithium batteries.
