24V lithium batteries are divided into 6 series of 22.2V lithium batteries and 8 series of 25.6V LFP lithium batteries, and the nominal voltage is collectively referred to as 24V. HLC battery is a factory with 8 years of experience in customizing lithium batteries, with mature technology, high safety and long cycle life. Our company can design and develop 22.2V/24V lithium battery packs with different capacities, sizes and shapes according to customer needs.
Our main features:
Application fields: intelligent robot power supply, solar energy application, portable energy storage, the urban signal at bus stations, billboards, etc.
The 24V lithium battery pack converts the conventional 7-cell lithium battery pack (rated voltage 25.9V) into a regulated output battery pack through the DC-DC step-down module to meet the working requirements of the equipment. The battery core materials are lithium cobalt oxide, ternary or lithium iron phosphate, and the capacity ranges from 1Ah-200Ah, which can be customized according to customer requirements; The battery size can be customized according to customer requirements, and the operating temperature is -20℃–+55℃. It is widely used in special equipment, robots, AGV, rail transit, medical electronics, emergency backup, exploration and mapping, commercial finance, instrumentation, consumer electronics and other fields.
Depends on how big your need for outdoor loads is.
6 series of 18650 theoretically have a no-load voltage of 25.2v when fully charged, but this is the open-circuit voltage. Once a load is applied, the voltage drops, and the greater the load, the greater the voltage drop.
This is the voltage curve of LG and Lishen 2600 at 1C discharge. You will find that under 1C load, the voltage of LG26000 is below 3.7V most of the time, the average voltage is only 3.5V, and the 6 series are 12V. That is about half the time, the output voltage of the battery pack will be less than 21V. When the battery pack just discharges 3/4 of the power, the inverter will shut down the low-voltage protection. It would be better if it was replaced by a domestic force.
And to replace that kind of electric car battery, you need two bottles. Although the electric vehicle battery rarely discharges at 1C, its monomer capacity is above 20Ah, and the current of 0.2C can reach 4A.
Reverse your load according to the principle of the inverter. Assuming you are using Lishen 2600 battery cells, 6 series and 4 parallels, fully charged, your inverter efficiency is about 93%. Then when the battery cell is discharged at 1C, the power of your electrical appliance will be 220W. When this is still fully charged, as the voltage of the single battery gets lower and lower, its current will increase, which is a vicious cycle. So in fact, you will find that even the Lishen 2600mAh battery cannot release its full power. 220W, a micro electric kettle also needs 500W.
Of course, it does not mean that high-power electrical appliances cannot be carried. Lishen 2600 power battery, according to experience, can last for a maximum discharge of 5C. According to the calculation of 6 series and 4 parallels, it is not a problem to bring a miniature electric kettle. However, with 6 strings, over-discharge is still not enough. With high-power electrical appliances, when the voltage drops to a certain extent, the inverter will first protect against under-voltage. At this time, the battery pack has a lot of power.
So if you want to use as much battery power as possible on the 24V inverter, preferably 7 series. If you want to use high-power electrical appliances, at least get 13 series and 5 parallel, and add a 48V inverter, so that the assembled battery can also be used in electric vehicles.
To understand the real demands of the 24V lithium-ion battery, you need to provide the lithium battery size, electrical performance requirements, output requirements, and functional information.
Evaluate a solution and quote the known parameters provided by the customer, also provide full datasheet for reference.
After the customer’s approval, we will start to make samples for 24V lithium-ion battery pack, and provided a charging and discharging cycle curve and data.
Assist and track customer test results, as well as customer’s overall equipment operation effect.
We will discuss with customer certificate works based on the final country and applicate requests. It may be MSDS, UN38.3, IEC62133, KC, PSE, etc.
Develop process documents and BOM sheet, purchase materials, arrange staff production, quality personnel monitoring, and random inspection, and package and shipment.
