What does a 512V 100Ah lifepo4 battery consist of?

The 512V 100Ah lifepo4 battery is the same as conventional lithium batteries. It is composed of positive and negative active materials, separators, electrolytes, current collectors, casings, etc.

When the lithium battery works, the above accessories play the following roles:

  • Cathode material: stores lithium ions and oxidizes them to produce electrons.
  • Negative material: accepts lithium ions and reduces electrons.
  • Separator: prevents electrons from flowing directly while allowing lithium ions to pass through.
  • Electrolyte: Provides an ion transmission medium.
  • Current collector: collects electrons generated by the positive and negative electrodes.
  • Shell: protects the battery’s internal structure.

Features of PVMars 512V 100AH lifepo4 battery

The cathode material selected for the 512V 100Ah battery produced by PVMars is a lithium iron phosphate (LiFePO4) battery cell.

This is one of the safest cathode materials in the world.

It has strong cycle stability, a long service life (12 years), and an environmentally friendly composition that is easy to recycle. Among them, the battery cell raw material suppliers we cooperate with include BYD, CATL, and EVE.

Our lithium batteries have:

  • More than 6000 depth cycles (DOD).
  • Allows more lithium batteries to be connected in parallel to add more capacity in the future.
  • 6-year warranty – If quality problems arise, new parts will be sent free of charge for replacement.

PVMars promises a 30-day return policy on all products.

15 days production time and 6 years free warranty

In addition, each PVMars lithium battery is equipped with a battery management system (BMS), which is also a vital component of lithium iron phosphate batteries.

BMS includes:

  • Monitor your battery’s voltage, current, and temperature.
  • Protect the battery from overcharging, over-discharging, over-temperature, etc.
  • Extend battery life.

Wholesale price of 512V 100AH lifepo4 batteries?

512V 100Ah lifepo4 batteries cost US$7180/unit (Valid for 30 days)

Please note that lithium batteries are priced on Wh, which is stored electrical energy.

It is difficult to tell the actual capacity (electric energy) of a lithium battery with the naked eye. Although the casing is marked 512V 100Ah, is the actual capacity that much?

Avoid buying fake batteries, which need to be tested to determine whether they are genuine. Please click on the “Battery Capacity Test Video” to get more battery secrets.

How much energy does a 512V 100AH lifepo4 battery store?

AH is a unit for measuring electrical storage equipment capacity. Its scientific name is “ampere hour”, which means that electrical storage equipment can continue to work for 1 hour when the power supply current intensity is 1A.

WH is a form of energy (electrical energy) and is equal to the voltage of the solar cell (V) multiplied by the AH of the battery.

The resulting WH value is divided by 1000, and the result is KWH (degree).

Conversion formula: 1WH = V * AH, 1KWH = 1WH / 1000.

That means that a 512V 100AH lithium battery can store a capacity of 512V * 100AH = 51.2vah / 1000 = 51.2kWh.

The last 51.2kWh / 5kW = 10.24 hours means that a 512V 100Ah battery can supply power to a 5000W electrical device for about 10 hours.

In layman’s terms, it means how many hours a lithium battery can work when power fails. PVMars senior engineer wrote an article to explain this issue. If you are interested, you can click on the orange font to get more information.

Can a 512V 100AH lifepo4 battery be used directly?

Its focus here is on what kind of electrical equipment the lithium battery is connected to.

The 512V 100Ah lithium battery can be directly connected and used if it is a DC fan or lamp.

Because the lithium battery outputs direct current. But if your load is an AC appliance, an inverter is required to perform DC-AC conversion to supply your load.

PVMars lithium batteries can be connected to any brand of inverter without communication protocol restrictions.

However, you need to provide the inverter parameters – such as DC voltage, power, output voltage, etc. Of the inverter (specifically reflected in the inverter). The side or back of the inverter. You can take a photo and send it to [email protected])

Why choose PVMars lithium batteries?

For your safety, PVMars is not just talking, we take practical actions to protect your property and life!

PVMars’ lithium batteries need strict testing before shipment, including temperature testing of lithium batteries.

Because the lithium batteries are temperature-sensitive if it exceeds -20℃, unqualified lithium batteries will stop discharging. You can see how PVMars performs temperature extreme testing in the video below:
