We only source high A-grade cells from the official sources (never use fake or cheap cell pack sell at lowest price to attract buyers). Assemble all our batteries in our factory, using custom parts we design and then manufacture on our own CNC machines. Each pack is ran through a full charge and discharge before leaving our facility to make sure you are getting every amp hour you paid for. Cell in the pack is fused (just like almost all of the batteries we supply). Cell level fusing, means that in the event of an internal short circuit in the battery (which the BMS cannot protect against), then all that will happen is that some sacrificial links will safely open, preventing any of the cells or cabling from overheating and becoming dangerous.We don't take chances when it comes to our batteries or your safety!
