12V 24V 36V 48V 100Ah 200Ah 400Ah Lithium LiFePO4 Battery 200A BMS 10000+Cycles

12V 24V 36V 48V 100Ah 200Ah 400Ah Lithium LiFePO4 Battery 200A BMS 10000+Cycles Product Description: Lithium iron phosphate batteries are a mature alternative to lead batteries, possessing all the advantages of lithium iron phosphate technology. This storage system is specifically developed for today’s high requirements for batteries, providing maximum safety and long-term availability even under regular deep discharge. This technology can achieve an extremely long lifespan, making these batteries ideal traction batteries. In addition, even under extreme loads, it can significantly reduce weight, have huge energy reserves, and maintain stable voltage. [10-year lifespan and 10-year after-sales service] LiFePO4 batteries contain 10000+cycles, and each lithium battery can run for more than 10 years, equivalent to 3 lead-acid batteries. We provide 10-year after-sales service for batteries [High charging speed] Our LiFePO4 battery can reach 80% power after one hour of charging, while lead-acid batteries can only reach 20% under the same conditions. In the case of limited charging time, choosing a lithium battery can quickly obtain sufficient energy. [Lightweight and easy to install] Our LiFePO4 batteries are lighter than lead-acid batteries of the same capacity. Our LiFePO4 battery weighs only one-third of lead-acid batteries. More convenient to carry, with no risk of leakage in any installation direction, and safer to use. [Capacity Expansion] Our LiFePO4 batteries can be connected in parallel and series to achieve greater capacity and voltage. 12VLiFePO4 battery supports connection, up to 5 identical batteries can be connected in series 24V LiFePO4 battery supports connection, with up to 3 identical batteries connected in series 36V/48V LiFePO4 batteries do not support series connection, only parallel connection is supported Only parallel connections are not restricted [200A BMS protection] The battery has an integrated BMS (Battery Management System), low self discharge, which can prevent overcharging, deep discharge, overcurrent, overload, short circuit, battery voltage self balancing, high temperature discharge cut-off, and low temperature charging protection [Multiple application locations] LiFePo4 lithium battery is safe, efficient, and portable, suitable for camping, RV, caravan, electric boat, golf cart, tool trailer, solar panel, children’s car, or as a backup power source. Self-developed unique BMS Our HRBEENERGY lithium iron phosphate batteries has a built-in BMS(Battery Management System) to prevent the battery from being damaged by over-charging or over-discharging, over-current, short-circuit or high/low temperature and failure. And the BMS will protect the lithium iron phosphate batteries in these cases The BMS collects the voltage and temperature of each cell in the battery pack, the charging and discharging currents, and the total voltage of the battery pack during charging and discharging, thus preventing the battery from being overcharged or overdischarged. A built-in high temperature/low temperature cut-off prevents charging/discharging when the temperature reaches a certain threshold. LiFePO4 Manufacturer, we are the professional. HRBEENERGY, a professionalLiFePO4 battery factory with its strong core technology R&D team and a complete R&D system,as well as a independent laboratory. It has a wide range of product models, excellent product quality and superior consumer services which regularly launches new products. Our HRBEENERGY lithium iron phosphate batteries is widely welcomed by consumer for its superior charca teristic and grade A cell. Green Energy: Our lithium iron phosphate batteries are green batteries, which do not contain any heavy or rare metals and are more friendly to the environment. They also have certain advantages of recycling of batteries. High Energy Density: Lithium batteries are a kind of high energy density batteries that can store a large amount of electrical energy. High energy density makes lithium-ion batteries have the characteristics of small size and light weight, which is also one of the reasons it can be widely used in various fields. Stable performance: Our HRBEENERGY lithium iron phosphate batteries has reliable quality and durability to provide your equipment with stable performance. Greater Power: We have a greater power to suport the battery operation that eliminate the need for frequent charging Long time & Deepcycle: Lithium-ion batteries have a relatively long lifespan, which can reach 4000-15000 deepcycles. Under appropriate use and storage conditions, the life of lithium-ion batteries can be better guaranteed. Low self-discharge: no need to worry about energy depletion even when idle for a long period of time For more details, please consult customer service, 24 hours online ServiceShippingReturnsAbout usContact usServiceIf you have any questions about the product, please contact us through EBAY, We will reply to you within 24 hours (reply within 48 hours on non-working days) ShippingFast Shipping: Shipping within 24-72 hours after payment, we do not arrange shipping onweekends and holidays.
