52V | 28Ah Lithium Ion Battery Pack



This EMP lithium battery pack is shrink wrapped with flame retardant fish paper inside to improve safety. We test each cell first before we build the battery pack to ensure the cells are properly balanced. We build every battery to order; nothing sits on the shelf here as we want to only send the freshest battery and we educate all our customer not to leave the battery sitting for a long time without charging as well. Check the video below to see what's inside of an EMP Battery. 


Difference between 52V battery vs 48V Battery 

52V battery if paired with a compatible motor will give you a bit more acceleration ( Torque ) . For example the bafang Mid drive motor 48V has a voltage range of 40V to 58V which most 52V batteries are 14S which means 4.2 x 14S is 58.8V so a 52V battery will work for a 48V motor for Bafang. When this is paired together it will be slightly more powerful and will give you more acceleration vs a 48V battery. 

Having a high steady voltage is great for you motor output so using a 52V battery system will make you motor run more effectively over the course of time if you are looking to draw more power from the motor. 48V batteries will over time start to drop in voltage over time and so will a 52V battery so having a 52V battery over time will be just like owning a 48V battery once the voltage starts to sag a bit but this can be avoided by having a good BMS with passive or active balancing.
