This is the LG HE4 18650 2500mAh 20 amp battery. It was originally designed for use with German power tools so you get an idea of how powerful it is. It is an upgraded version of the LG HE2 which would sometimes get hot when it was being used a lot. This can handle 30 amps easily because it has a peak max discharge of 35amps. As with all rechargeable batteries it is really important to be careful with this battery. You need to make sure that you use the correct charger with it and that you charge it fully before us. Make sure that you only charge batteries of the same brand together and that you are very careful with what you do with fully charged batteries. Make sure that you understand the full safety implications before you start to use your battery and also make sure that it will work with your device before trying it out.
