Fully Tested New Down-tube Batteries Using 18650 cells
Posted on January 10 2017
EMP will be releasing their 18650 batteries collection this upcoming spring time and we are super excited about bringing you 100% fully tested batteries. All of our batteries are tested individually per cell before we build the complete battery pack. This is very important as in terms of the battery pack your system is only as good as your weakest cell. Here's our battery tester that all of our 18650's go through.
Here is a list of batteries coming up for sale: all under $$$500$$$
Most E bike batteries have around 40 cells in side of the complete battery pack. The reason why it is important for each cell to be tested is to ensure the battery has the correct life expectancy. If all the battery cells are rated at around 3000 mAh per cell but there is one cell that is only 2500 mAh then the BMS will do everything in its power to protect the weakest cell (2500 mAh). At EMP we make sure that all cells are paired together before we start to build the complete battery. The other down fall of having untested cells inside of your battery pack is that the weaker cell will make the other cells work harder and will degrade the other working cell over time.
