1.2. Charge and discharge warnings

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.

1.4. Disposal of lithium batteries

Lithium NG 51,2V battery manual 1.3. Transportation warnings The battery must be transported in its original or equivalent package and in an upright position. If the battery is in its cardboard packaging, use soft slings to avoid damage. Ensure that all packaging materials are non-conductive. Cartons or crates used to transport lithium batteries must have an approved warning label affixed. Air transportation of lithium batteries is prohibited. Do not stand below a battery when it is hoisted. Never lift the battery at the terminals or the BMS communication cables; only lift the battery at the handles. Do not tip over the battery.

Dropping and tipping can lead to physical damage , which may expose internal cells and pose safety risks such as Fire and Electric shock. Batteries are tested according to the UN Handbook of Tests and Criteria, part III, sub-section 38.3 (ST/SG/ AC.10/11/Rev.5). For transport, the batteries belong to the category UN3480, Class 9, Packaging Group II and have to be transported according to this regulation. This means that for land and sea transport (ADR, RID & IMDG) they have to be packed according to packaging instruction P903 and for air transport (IATA) according to packaging instruction P965. The original packaging complies with these instructions. 1.4.

Disposal of lithium batteries Do not throw a battery into fire. Batteries must not be mixed with domestic or industrial waste. Batteries marked with the recycling symbol must be processed via a recognised recycling agency. By agreement, they may be returned to the manufacturer. Page 2 Safety precautions
