The Benefits of HiPower Lithium Electric Car and Vehicle Batteries

Why a HiPower battery is a better source for you.

“There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper, and the people who consider price only are this man's lawful prey.”

-John Ruskin

Even though our pricing is probably the lowest priced prismatic LiFePO4 battery you will find, purchasing an item based upon price alone is often short sighted. Many factors should be taken into consideration when a company or individual selects a particular battery for their application. Chief among them is quality, lifespan, and warranty. It is easy for companies to make claims. Often, the responsibilty of establishing the true facts falls back on the buyer. Wild eyed claims by some companies regarding their batteries' life or ability to handle high currents are difficult for the average buyer to substantiate. Here are some interesting facts:

The Source:

The Electric Car Company of Utah, has spent a good deal of time evaluating various sources for lithium batteries. As it turns out there are quite a few lithium battery manufacturers. However, finding one source that is the best value for an Electric Vehicle is daunting. After a lot of e-mails and phone conversations we have concluded that the Lithium-ion Phosphate (LiFePO4) battery packs that we can offer through Energetech will give our customers the best value in performance, construction, energy density, longevity, price and delivery. The Factory backs their batteries with a two year warranty. In addition, lithium batteries need special care when being charged and discharged. Therefore, special due diligence has been exerted to find a superior Battery Management System "BMS" which will assure the customer maximum battery life. We know the one thing that you want for your vehicle is a reliable battery pack that will assure you years of satisfactory driving pleasure.

Quality and useful life parameters:

Lithium batteries are rated by their discharge rate. This is designated as a "C" rating. A "C" rating means the amount of current that can be discharged from the battery over a specified period of time. As a general rule, lithium batteries' standard discharge rate is 1/3 of the C rating of the battery. For reasons I have never been able to fathom, the manufacturers do not rate their batteries for these reasonable continuous discharge current conditions. As an example a 1C HiPower 200 AH battery can be discharged continuously at 200 Amps. It is not recommended that you do that but the battery is fully capable of producing a 3C or 300% or even up to a 5C which is 500% of its Ampere Hour "AH" rating for short periods of time shown on the specifications.

HiPower frowns on the practice of just pulling batteries off the shelf and shipping them out immediately. Each battery pack that they sell is selected so that they are a matched set. As time goes by you will realize how important it is to getting balanced and matched batteries in a pack. That"s because Lithium batteries can be damaged by overcharging or over discharging. A good BMS should shut your charger off at about 3.65 volts per cell and never allow the voltage to exceed 4.0 volts or the battery life will be shortened. If the batteries are not balanced then the best battery will be charged up to 3.65 volts. At this voltage set point a good BMS system will detect this one cells condition and shut the charger off. Leaving he rest of the pack only partially charged. Conversely , lithium cells should never be discharged below 2.0 volts or it also is hard on the cells life. So most BMS systems are set to shut the pack discharge off when one of the batteries get down to about 2.2 to 2.4 volts. At this point, the other batteries in the pack still retain usable energy. This will materially affect your range. A matched set of batteries goes a long way towards preventing this condition.

Our delivery on the battery pack will be about 8 to 12 weeks. The company requires 10% of the total price down as a non-refundable deposit. The balance will be due when the batteries are ready to be shipped.

All HiPower batteries will be factory warranted for two years. This warranty is not prorated like a number of other companies. It is a full replacement warranty.

The Competition:

Finding the right Lithium Battery Source proves to be only part of the challenge facing the potential Lithium Battery user (you). The next hurdle is finding a dependable vendor who will deliver the goods to your door. All Chinese Lithium manufacturers are required by the government to be paid cash in advance of shipping. This means that you have to depend on your supplier to ship what is ordered.

Our Company:

Our company has been in business for 34 years. We won't cheat you! Products that you order from the Electric Car Company carry our word that you will receive exactly what you order. HiPower will give a full replacement warranty on all batteries that are not mis-used for two years.



If you read the Hipower specification sheets, you will see numbers like "3C" and "C/2". These correspond to battery discharge rates. "C" is the current ideally delivered by the battery in one hour. For example, 1C for a 160 Ah (Ampere-hours) battery is 160 A (Amperes). 2C for a 160 Ah battery is 320 A, and C/2 for a 160 Ah battery is 80A.

Hipower New Energy Group Co.,Ltd

  

1. Company brief introduction:

(1). General information about our company and our products: LiFePO4 (lithium iron phosphate) rechargeable batteries, along with a unique patent pending Battery Management System and Lithium battery charging system.

(2). Shangdong Hipower Energy Group--- A pioneer in LiFePO4 battery production

Our scale :

With our total production ability of over 3 Million AH, our Hi-power Energy Group's factories are well equipped to meet the need to supply a growing demand for LiFePO4 batteries all over the world.  We have two large factories: One is in Zhaozhuang which covers an area of 5,600,000 square feet; the other is in Yantai with over 1,000,000 square feet. Our newest Zhaozhuang plant is completely equipped with the newest state of the art battery manufacturing equipment, to meet the requirements for certification by ISO, CE, ROHS, UL, and the Tianjin 18th Research Institute. With the latest professional Chinese lithium battery testing center, we can now provide a unique center to focus on the latest Lithium battery technology needs of the  Scientific, Industrial, Solar, and Automotive Industries.


Our history :

•        We have been in the LIFEPO4 battery manufacturing business for the last eight (8) years and have produced lithium batteries in mass production for the last six (6) years.  That is longer than any other Chinese LiFePO4 manufacturer.  

           

Our Market :

•       We were the first company in China to make 288V 200Ah LIFEPO4 battery packs and have successfully sold them to highly specialized companies all over the world. That was 3 years early than any other LiFePO4 supplier.  In 2008, HiPower produced over 25% of all the LIFEPO4 batteries produced and exported from China.  

 
Our patents :

As shown on the website of SIPO (State Intellectual Property Office of People's Republic of China) HIPOWER is the second largest Chinese company and is among the top 20 companies listed holding the largest number of lithium related patents. 

 

Our achievements :


In China HIPOWER is considered a pioneer in the development of LiFePO4 battery construction and manufacturing, HIPOWER is the only company that has been interviewed and praised by China National TV (CCTV) for their great contribution in the field of energy on The 60th Anniversary of China Energy in October 2009.

 

Why choose a HIPOWER lifepo4 battery ?

Compare HIPOWER with other China energy suppliers who only began to engage in building LIFePO4 batteries as late as one year ago or just this year, and you will see that we are the one of two companies who started to research and develop LiFePO4 batteries as early as 5 years ago and has successfully build and exported 388v 200ah battery packs to customers 3 years earlier than our main Chinese competitors. So we have gotten a big head start in this industry.  As a result of this fact HIPOWER can now produce full solutions for LiFePO4 battery packs + charger + BMS right now. Our battery packs cover a range from 12v /24v/48v/72v/144v to 388v with capacity of 10ah/20ah/30ah/50ah/100ah/200ah/600ah.  

 

These packs are widely used in rechargeable power applications. Coupling these packs with our HIPOWER'S unique, LIFEPO4 charger with their newly Patented BMS (Battery Management System) which can monitor and equalize each single cell during charge and discharge makes for a winning combination. Some of our power solution products have recognized and applauded in advanced countries.

 

Thanks for HIPOWER'S 5 years of experience; one of our advantages is that we know how to produce large capacity batteries. We can produce 200Ah/600Ah single cells now and we are now designing a 1000Ah single cell. There are few others who can successfully mass produce more than 50Ah cells. They just build the pack with small single cells like the 18650/26650 to be in paralleled together. To combine that many small cells together won't give good performance because all of the cells within the pack cannot maintain near enough consistency within all of the cells. This serious inconsistency will eventually lower the life of the whole battery pack.

 

OUR TERMS AND CONDITIONS:

 

OEM battery service is welcome. Our 20 staff R&D department would be ready to serve you at any your requirements.

 

2. The delivery terms and Payment term

Delivery time: For products, the normal production time is 25 days –55 days if without stock as per how many orders are  still  in production  ; We can offer to you the pack around 10 days if with stock. If customer only need single cells instead of battery packs , the delivery time would be much faster.

◇           Payment term : L/C or T/T payment before shipment

◇           MOQ: 1 piece for a sample, or one set of pack to qualified customers.

Rapid Charging Ability  

HIPOWER'S battery can quickly and safely be 85% charged within a half hour under 2C fast charge conditions and can withstand a high discharge rate of 5C to 10C, which is 5 times faster than any other lithium battery presently available on the market.

Have deep DOD (depth of discharge):

LiFePO4 can be fully discharged, whereas a lead-acid battery can only be discharged to 70% capacity without long term detrimental effects on battery life, over discharge can also destroy a lead acid battery. So with the same capacity, HIPOWER'S battery is more powerful.

Voltage Stability:

Lithium batteries voltage stability is better than lead-acid, Ni-MH, Ni-Cad b lead-acid 2V cells; Ni-Mh/Ni-Cad: 1.2V/cell, moreover, the voltage would remain between 3.2V down to 2.85V for 85% of its discharge time.

No memory effect:     

Nickel Batteries exhibit memory problems.  LiFePO4 does not.


Environmentally Friendly

LiFePO4 is non-toxic, non-contaminating and contains no rare metals, The cell chemistry of LiFEPO4 is UL, CE, and SGS/ROHS approved, They are

easy to dispose because they contain no heavy metals

Wide working temperature range

From -25°C+70°C (Extreme cold and hot weather will not affect its performance)

Flexible Form Factor 

Lithium batteries are small in size and light in weight. Lithium is 1/3 the weight of lead acid and 65% weight of NIMH batteries. Lithium is 60% the size of a lead acid but has twice the run-time of a lead acid battery.

Battery Life:

LiFEPO4 batteries have a life cycle up to 2000 cycles which is 7 times the life of a lead acid and 2 times NIMH, LI-ION cobalt, LI-MN batteries life.
