1.0 BATTERY TS-SERIES

LCP and LFP Model

2.0 CHARGING & DISCHARGING METHOD

2.1 CHARGING
    For best charging, use special Solid State Lithium ion Power Battery charger, charging in constant current and limited voltage. Connect their polarities(+ and -)according to the marking inside the battery.
    Charging should be separated into two stages with constant current, starting charging is less than 1C electric current (the best charging current is 0.3 times of rated capacity). When the battery is fully charged (the highest setting voltage is 4.35V),change to constant voltage charging. The charging will stop when the current is less than 100mA. When multiple battery cells are connected in series or parallel, each cell should be monitored against voltage overcharging.

2.2 DISCHARGING
     The lowest discharge voltage of a single battery unit should be strictly controlled at 2.6V (the optimum constant discharge current is 0.3 times of the rated capacity for LCP model and 3 times for LFP model). If durable application is not taken into consideration, this battery can achieve instantaneous large current discharge with the current reaching over 3 times the rated capacity.

3.0 MAINTENANCE

3.1 BATTERY DAILY CHECKING
        If find any cracked phenomenon, replace the battery immediately.
3.2 VOLTAGE CHECKING
    a. Standard battery voltage is 2.6～4.35V.
    b. Use voltage meter to check every single battery voltage. If find the battery voltage is less than   
       (≤2.3V), the weak battery needs to be charged.

       (Do not remove the connection board out of the battery.)
    c. If find any single battery's voltage is zero, please inform the manufacturer or nearest dealer for replacement.

4.0 COMBINATION

4.1 The numbers of batteries can be stringed or combined into battery packs according to the users requirement. For the best result, please follow the instructions.
    a. when  ex-factory, the products quality are strictly controlled single battery should be battery groups. When user disassembles the battery group, each single battery should be discharged to 2.6V before disassembling the battery and the connecting board should be screwed tightly to connect into the new battery group.
    b. During repacking the batteries, if find the case swell and puff, it is regarded the battery is normal. Please notice to screw the connecting boards tightly.
 

5.0 STORAGE

5.1 The battery should be stored at charged condition, that is to charge at 4.35V.
5.2 Storage temperature is 5～40℃ in an open, well-ventilated clean area.
5.3 Do not expose in sunshine, and never near heating place less than 2 meters.
5.4 Do not allow machine crash or heavy press.

6.0 TRANSPORTATION

6.1 Do not expose in sunshine, rainfall and prohibit heavy machinery crash during transportation.
6.2 Prohibit throwing, rolling and pressing. Carefully handing during loading and transportation.

7.0 FIRE PRECAUTION

    Misuse of battery arising of fire, should use dry-powder fire extinguisher, or cover by sands and mud, or use carbon dioxide fire extinguisher.

8.0 DISPOSAL

    After several times of using, if the charging and discharging rated capacity is below 50%, you should call or fax to the manufacturer to recollect batteries, careless disposal may arise environment pollution.

9.1 Never short the terminals or by other ways (e.g. Needle punch, press, etc.) which may cause short circuit.
9.2 The battery and battery pack can be used in an environment of –20℃～75℃. In case of use beyond the maximum temperature range, forced ventilation and heat dissipation should be implemented. If the battery is used at a low temperature, its discharge current will become smaller and the voltage will drop rapidly, possibly affecting its power output. In this case, after discharging the battery continuously for three minutes at a small power, with the battery temperature risen up to 30℃, the battery will resume normal discharge.

9.3 If this product is used in a high and cold environment, a thermal insulation case can be designed for the battery, and directly heating the battery exterior can better guarantee the discharge performance of the battery.

9.4. When several single battery units are to be connected in parallel or in series for use, strict selection must be carried out for batteries with identical voltage and internal resistance. Otherwise some batteries might be over-charged or over-discharged due to inconsistent charging and discharging, resulting in capacity decrease and voltage drop, even a zero voltage might be possible.

9.5 In addition to strict selection of batteries with identical voltage and internal resistance for connection in parallel or in series, it is also required to ensure each single battery unit in the battery pack to be evenly charged. Generally a voltage difference ≤50mv between respective batteries connected in series indicates a normal charging state and when the voltage of each single battery unit is at 4.3 ~4.5V, it means that the charging saturation state has reached. In this case, no further charging of the battery is allowed.

9.6 The self-discharge rate of the Lithium ion Power battery is ≤5% per month. After one year of storage, its capacity may decrease and its voltage may be relatively low. In this case, just repeat charging and discharging the single battery unit 2 or 3 times with a small current (a constant current of 0.1CA and a constant voltage of 4.35V for charging, while a constant current of 0.1CA and a constant voltage of 2.8V for discharging), after activation the battery will resume normal functionality.

9.7 The most obvious disadvantage of the Lithium ion Power  battery is that it is not adaptable to long-term and large constant current (≥1CA) discharge. Therefore, to use this product, the load power must be designed to precisely match the capacity of the battery pack. Otherwise the battery capacity will decrease rapidly, and its service life will be shortened.

9.8 Scientific and correct use of the Lithium ion Power  battery will not only bring you a pleasant frame of mind, but optimize the performance of all your auxiliary products as well.

Example (1): For an electro-powered car which is designed as the total DC voltage being 260V, the maximum motor power output being 40KW, and the covered mileage after charging once being 200KM, the Lithium ion Power batteries must be configured as 72 single battery units with 200AH each to be connected in series.

Example (2): For an 43-seat luxurious electro-powered bus which is designed as the total DC voltage being 390V, the maximum motor power output being 180KW, and the covered mileage after charging once being 300KM, the Lithium ion Power batteries must be configured as 90 single battery units with 1000AH each to be connected in series.

9.9 When multiple battery cells are connected in series or parallel, each cell should be monitored against voltage overcharging.

9.10 Never screw off the safety valve at the battery end in any case to prevent from danger.
