Product Description

rechargeable 48v 50ah lifepo4 battery pack for 4kw golf car 

Advantage of  lifepo4 battery
 1. Green product
 LiFePO4 material is no harm to enviroment and human being .
 2. Cycle life
 over 2000 cycle times, 8-10 years life.
 3. Very safe
 It have the best safety and steady performance,no fire ,no exploding under the condition of over-charge.
 4. Light weight and smaller dimension
 The dimension  compares with other battery.about 1/2-2/3 weight of lead acid 
 5.Great capacity and more powerful,rechargeable battery
 We can install many single cells in series and in parallet and it can fully discharge memory effect
 It can be recharged anytime,no reduction of the capacity.

Testing method


Over-charge performance

No exploding, No fire
The highest temperature <130°C

After standard charge ,charge with 3C5A to 72V, then change to charge with constant voltage and stop charge until the current is 0.05C5A, check the temperature and appearance of the battery.


Over-discharge performance

No exploding, No fire

After standard charge,discharge with 0.2C5A to 32V,then connect the positive and negative with 10Ω resistor,rest for 60 minutes.check the temperature and appearance of the battery.


Short-circuit performance in normal temperature

No exploding, No fire
The highest temperature <130°C

After standard charged,keep in bell glass and connect positive and negative to short-circuit(the total impedance is not over than 50mΩ),stop testing when the temperature of the battery reduce 10 °C .check the temperature and appearance of the battery.


Nail performance

No exploding, No fire
The highest temperature <130°C

After standard charge,lay on the nog,connect with thermocouple,then at a height to impale the middle of battery rapidly with a diameter of 3mm nail.,check the temperature and appearance of the battery.


Heating impact safety performance

No exploding, No fire

After standard charge,lay in a hot case,connect with thermocouple,with speed of(5 °C±2 °C)/min to up to 150 °C±2 °C then keep for 30 minutes.check the temperature and appearance of the battery.

Cylinder lifepo4 VS Squre lifepo4
cylinder battery is higher quality  and better choice as power enegery . That is the reason we choose to R&D cylinder lifepo4 battery. And now , we are the biggest cylinder lifepo4 battery manufacturer in China.
Lifepo4 VS Lead acid
lifepo4 battery has 8-10 years life,which is five times lead acid battery, and one third weight of lead acid battery. The most important ,lifepo4 is no pollution and harm to humanbeing and environment.

Custom-made special dimension,even provide Brand packing design.
The quality guarantee is 24 months from our B/L date.
100%T/T for sample order ,30% T/T for bulk order in advance,70%T/T before delivery.
