FAQ on Lifepo4 battery packs

What are DNK Lifepo4 Batteries?
  • Our lifepo4 batteries work great in all 12V-48v vehicle applications (include but not excluding solar street lighting, solar storage,Solar Energy,UPS system,Golf Trundler,Electric Vehicle,EV car , Power Tool and RC hobby.Golf Car, Golf Trolley, Telecommunication Base Station,Telecom System, medical/hospital cart,Mobile Medication Carts,, Hospital Furniture, Hospital Trolley, Commercial Furniture). Our batteries are the smallest, lightest and most POWERFUL batteries available compared with our competitors.
  • What is the range of voltage for the batteries?
  • 12V 24V 36V 48V 20AH 40AH 100AH batteries, with pvc or plastic casing
  • What can I use a LiFePo4 Battery for?
  • Power Tool and RC hobby.Golf Car, Golf Trolley, Telecommunication Base Station,Telecom System, medical/hospital cart

    How long will my Lifepo4 BATTERY Packs Last?

  • That depends on many factors. In case there is no abuse, the DNK batteries are expected to last 5 to 6 years. Under ideal usage and storage conditions, we expect 8 to 10 years.
 
  • Why Your batteries are a little cheaper then your competitor?
  • All of our lifepo4 batteries are manufacturered our own factory, and there is no markup -you are dealing with factory. The other reason is we are producing in large volume,and thus can buy cheap material in some way, by passing the value to our customers, we want to work closely with you to get more market.
  • Why Lifepo4 Batteries? What's the Pro's and Con's of LifePo4?
  • Basically, LifePo4 Battery Cells have the following features:

     

    -High Energy Density , from Laboratory testing, it can  theoretical reach a capacity of 180mah/g and mass production capacity as high as 165mah/g.
    -10x Longer Life span     In comparison with lipo battery which has a cycle life of 500 or 1000 cycles, LiFePO4 battery can extends its battery life up to 3000-5000 cycles.
    -High temperature performance, since lifepo4 batteries are mostly used for solar storage, street light, mobile satellite station, Ebike or even EV Car, so it's very important to have chemicals that can endure high temperature, for LiFePO4 battery, it can have  High thermal stability of phases up to 500C.

    LiFePo4 batteries are considered to be safe, non-flammable and non-hazardous by international regulated standards among all kind of lithium battery packs

  • What is BMS and Do I need BMS?
  • BMS is short for battery management system, which is an electronic regulator that mainly designed to monitor and control the charging and discharging voltage and current of lifepo4 battery cells or other rechargeable cells .

     

    For Battery packs that contains too many battery cells, since battery cells voltage and capacity is not performing the same all the time, that's why BMS comes out. A BMS is a simple electronics system to measure and control voltage and current. and it will stop charging when the desired voltage is reached.

    For example, in 10 cells pack, some battery cell may reach its full capacity already, while others might only 80% full. In case battery cell are already charged full, the BMS will shut down the power flow, in case there is no BMS, the already fulled charged battery cell will go on with the charging and thus will short its life or even cause heat or fire.

    Some BMS can even monitor many factors such as temperature,humid,etc.. some can even send data to computer or App, so people can read the data on time.

  • Can I Custom my battery packs? Can you Design BMS for our new invention?
  • Yes welcome to contact us.
