Battery connection:

GEL, ACID, LiFePo4 batteries with M6 / M8 threaded posts, stainless steel screws and washers are added to the battery. Stainless steel is a good idea but not complete. Stainless steel is a resistive material that can damage the battery if someone makes a mistake while connecting. Poor contact is when the current flows through the stainless steel gasket, the pad constitutes too much resistance and starts to heat up, the temperature is so great that the heating strip battery starts in the housing what battery will lose its seal melting, the heating rod can cause ignition and even explosion . If the engine is powered off, it will lead to poor connection. We turn on the high gear and the engine will start to flow for a while and then deteriorate (loss of power)
