About Us

Brand Origin

QH Technology Co., Ltd. with 12 years of technology accumulation in lithium production, has always adhered to the most stringent quality and safety standard,  providing the market with reliable and durable products and building its brand with core competitiveness. At present, lithium iron phosphate battery is widely used in outdoor camping, RVs, golf carts, ships, power generation, energy storage devices and many other fields. Its emergence is a breakthrough in lithium-ion battery materials and has become a hot spot in the new energy industry. Although lithium iron phosphate products are currently in the infancy stage of the industry, with the tension of energy problems in various countries, lithium iron phosphate batteries will become the mainstream batteries and this industry will have a good development prospect. With technological innovation and battery solutions for multi-application scenarios, QH is devoted to building a smart grid and creating a better future when everyone is able to procure enough power through our products. 

our company

Welcome to our factory

QH Technology Co., Ltd. provides one-stop OEM/ODM product solutions for lithium battery packs. Our technicians ensure that each battery meets the high standards of performance and safety as well as the special requirements of our customers. QH mainly customized products according to customer requirements, such as voltage, discharge current, cell requirements, protection requirements, shells and so on.

FAQ

Our batteries can be purchased online. We have five modes of transportation to choose from: Express (UPS/FEDEX), Air Shipment Door to Door Service, Sea Shipment Door to Door Service, Air Shipment, Sea Shipment. You can choose the transportation mode suitable for you according to your needs.

QH was founded in 2010. Our company is committed to developing environment-friendly and efficient energy storage solutions.

BMS is Battery Management System. The BMS protects the cells from getting damaged — most commonly from over or under-voltage, over-current, high temperature, or external short-circuiting. The BMS will shut off the battery to protect the cells from unsafe operating conditions. Our batteries have a built-in BMS to manage and protect them against these types of issues.

No matter what battery is replaced, you first need to consider your capacity, power, and size requirements, as well as making sure you have the right charger. Keep in mind that you may be able to downsize your battery (in some cases up to 50%) and keep the same runtime when upgrading from lead-acid to LiFePO4. Most existing charging sources are compatible with our lithium iron phosphate batteries. Please contact QH technical support if you need assistance with your upgrade and they will be happy that you pick the right battery.

Of course, because there is no fluid inside of LiFePO4 batteries. This gives you the flexibility to install the battery where it is best suited for your application.

Simply charge your battery to 14.4 volts, disconnect the battery from your charger, and your equipment, then store in temperatures anywhere between 23°F to 95°F (-5°C to 35°C). For storage longer than 3 months, the recommended temperature range is 32°F to 77°F (0°C to 25°C), then it’s safe to store at a 50% state of charge. Unlike lead-acid batteries, a partial state of charge does not harm lithium batteries.

Battery life is measured in life cycles and our LiFePO4 batteries are guaranteed to 6000 cycles. Actual life expectancy is dependent on several variables based on your specific application. If used for the same application, a LiFePO4 battery can last up to 10X longer than a lead-acid battery.

Generally speaking, these two types of chargers can not be mixed. Otherwise, the battery will be damaged and scrapped. This is because the charging mode of the lithium battery charger is different from that of the lead-acid battery charger. Lithium battery is charged by constant current and constant voltage (CC / CV), while lead-acid is charged by a three-stage charge.

Lithium iron phosphate batteries can be charged in as fast as 1 hour. We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the datasheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.

For terminal customers, RS485 communication is generally not provided with the display screen. If it is customized by the company or technicians, we can make it according to the requirements of customers.
