Never short circuit a battery whatever.2.Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame. Make sure that the batteryroom is ventilated.3.Avoid touching or short circuiting wires and terminals. Be aware that the voltages on specific terminals and wires canbe up to double of battery voltage. Use isolated tools. Stand on dry ground and keep your hands dry.InstallationPlease installed in the room, avoiding direct-clearance,do not install in the wet environment, when use it outdoor,please install controller and batteries in the same place,and the batteries installed in the same place, the controllercan measuring the battery temperature, chargevoltage regulation.Attention:1.
