Lithium NG 51,2V battery manual 1. Safety precautions Observe these instructions and keep them located near the battery for future reference. The Material Safety Datasheet can be downloaded from the “Material Safety Datasheet menu” located on the Lithium Smart product page . Work on a lithium battery should be carried out by qualified personnel only. 1.1. General warnings While working on a lithium battery, wear protective eyeglasses and clothing. Any leaked battery material, such as electrolyte or powder on the skin or the eyes, must immediately be flushed with plenty of clean water. Then seek medical assistance. Spillages on clothing should be rinsed out with water.
Explosion and fire hazard. You must use a type D foam or CO2 fire extinguisher in case of fire. The terminals of a lithium battery are always live; therefore, metallic items or tools should not be placed on top of the battery. Do not wear any metallic items such as watches, bracelets, etc. Use insulated tools. Avoid short circuits, very deep discharges and excessive charge or discharge currents. Do not open or dismantle the battery. Electrolyte is very corrosive. In normal working conditions, contact with the electrolyte is impossible. If the battery casing is damaged, do not touch the exposed electrolyte or powder because it is corrosive. Lithium batteries are heavy.
To avoid muscle strain or back injury, use lifting aids and proper lifting techniques when installing or removing batteries. If involved in a vehicle accident, they can become a projectile! Ensure adequate and secure mounting and always use suitable handling equipment for transportation. Handle with care because a lithium battery is sensitive to mechanical shock. Do not use a damaged battery. Water will damage your battery. Discontinue use and seek further advice. 1.2. Charge and discharge warnings Use only with a Victron Energy-approved type NG BMS. Overcharging or deep discharging will seriously damage a lithium battery and may render it unsafe for continued use.
Therefore, an external safety relay is mandatory. If charged after the lithium battery was discharged below the “Discharge cut-off voltage” or when damaged or overcharged, the battery can release a harmful mixture of gases, such as phosphate. The battery can be charged between 5 °C and 50 °C. Charging it at temperatures outside this range may cause severe damage to the battery or reduce its life expectancy. The battery's discharge temperature range is -20 °C to 50 °C. Discharging the battery at temperatures outside this range may cause severe damage to the battery or reduce its life expectancy.
