Genuine Samsung 25R 2500mAh batteries are a pretty new cutting edge battery cell from Korea that can handle some really high current. This is the 25R5, the new green 25R. They are an updated version of the old "smurf blue" ones. The 25R is one of our favorites from our testing at high currents. The problem is there are many counterfeits on the market but you can be sure these 25R's are genuine. Extensive testing to be sure they're real so you can be confident you've got the real thing.
Battery safety is very important. Mistreated batteries can get extremely hot and/or vent which could cause injury. Always follow the following rules to make sure this doesn't happen. We are not liable for mistreated batteries.
