Product Description


12v 50ah lithium battery for solar power system
Why lithium-iron phosphate?

Lithium-iron-phosphate (LiFePO4 or IFR) is the safest of the mainstream li-ion battery types.
The nominal voltage of a IFR cell is 3,2V (lead-acid: 2V/cell). A 12,8V LiFePO4 battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.

Efficient
In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average leadacid battery is 80%.
The round trip energy efficiency of a LFP battery is 92%.
The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has  been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state).
In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.

Size and weight
Saves up to 70% in space
Saves up to 70% in weight

Expensive?
Lifepo4 batteries are expensive when compared to lead-acid. But in demanding applications, the high initial cost
will be more than compensated by longer service life, superior reliability and excellent efficiency.

Endless flexibility
IFR batteries are easier to charge than lead-acid batteries.
The charge voltage may vary from 14V to 16V (as long as no cell is subjected to more than 4,2V), and they do not need to be fully charged.
Therefore several batteries can be connected in parallel and no damage will occur if some batteries are less charged than others.
 

Battery Management System (BMS)
 Its essential functions are:
1. Disconnect or shut down the load whenever the voltage of a battery cell falls to less than 2,5V.
2. Stop the charging process whenever the voltage of a battery cell increases to more than 4,2V.
3. Shut down the system whenever the temperature of a cell exceeds 50°C.

In 2002, OptimumNano Energy Co., Ltd started the battery business in Shenzhen.

In 2006, OptimumNano began to focus on the production, Engineering, researching and manufacturing of LiFePO4-Lithium Iron Phosphate Battery, we believe the LiFePO4 shall be the best Lithium-ion Power Solution in the future

In 2008, OptimumNano finished the first Pure Electric Bus with LiFePO4 Battery, demonstrating and running for Shanghai EXPO.

In 2009, OptimumNano was awarded the honor of "National High-tech Enterprise".

In 2011, OptimumNano was the main vehicle power battery supplier of the 26th World Universiade Games.

In 2012, OptimumNano was selected as one the supporting company of "2012 New Energy Automotive Industry Technology Innovation Project", which was launched by the Ministry of Finance, the Ministry of Industry and the Ministry of Science and Technology.

In 2013, OptimumNano moved to new and bigger factory to meet our 500, 000 PCS daily production requirement.

In 2014, Shenzhen mayor Mr. Wang Rong and others come to our company to make researches and guidances and gave high praise for our company achievement in the new energy industry

OptimumNano set up the workstation for Academician Material Application. With around 500 R&D staffs, now we have more than 200 patents at home and abroad.

After over 13 years' development, OptimumNano has offices in local 31 cities, distribute our LiFePO4 batteries to over 40 countries in the world.
