Lipo Battery Production
Automated production lines ensure the consistency of the battery production in voltage, capacity, internal resistance, and low self-discharge rate, which is fundamental for the excellent performance of 4s lipo batteries. Furthermore, all the battery packs undergo 3 cycles of charge and discharge to fully activate their full capacity to meet customers’ standards.
Key Advantages
VTCBATT can support full customization of the 4S lipo batteries in different sizes, capacities, connectors, discharge rates, and cases. Just inform us of your specific requirement, and our professional engineers can provide you with the best 4S lipo battery proposal.
Strict cell match standards in 10mV voltage tolerance, 5mAh capacity tolerance, and 1mΩ to ensure excellent performance of the total 4s lipo battery pack.Furthermore,the 4S PCB with cell balance function can long-lasting power supply without any failure.
Featuring high-energy density 200wh/kg-300wh/kg,the 4S lipo battery can deliver more power than other battery chemistries and support high drain current to power the devices strongly.
Compositing of pure LiCoO2 material and nano-ceramic diagram, the 4S Lipo batteries can support ultra-long cycle life 1000 times and still maintain 80% capacity even after 500 times cycles.
Application
DronesDrones are normally operated under a 14.8V nominal voltage and high drain current to power the drones strongly. VTCBATT 4S lipo batteries are also provided with the
XT60 / XT30 / Deans / Molex/ JST-XH 4S balancing cable, which allows good connectivity of the drones during charge and discharge.
Robotics14.8V high nominal voltage can provide a stable voltage platform for robotics, which cannot only power the robotics continuously, but also be good for energy efficiency.
VTCBATT customized 4S lipo batteries allow different cases and performance for various robotics applications, such as Humanoid robots, medical robots, and delivery robots.
Led LightsSome portable lighting projects need customized 4S lipo batteries to deliver a steady 14.8V to power led strips in full brightness.VTCBATT can also design the 4-cell LiPo batteries in different sizes, capacities, and temperatures to power the led lights project perfectly.
Portable ProjectorPortable projectors become more and more popular and enable people to enjoy videos and movies at any time. The custom 4S lipo batteries can be perfectly fitted in the space-limited compartment to power the projectors continuously.
A: The 4S lipo battery lasts time that depends on the battery capacity and power consumption.
Normally, Lasting Time=Battery Capacity/Power Consumption. If the battery capacity is higher and the power consumption is lower, then the battery’s lasting time is longer.
A: The charging time depends on the 4s Lipo battery capacity and battery charger current.
At 0.5C standard charging current, the charging time is about 2.4 hours.
At 0.2C charging current, the charging time is about 6 hours.
The smaller the charge current, can extend the battery life.
A:Use a specific 4s lipo battery charger with a fully charged voltage at 16.8V, and a max charge current is 0.5C. It’ ‘s better to use the battery charger with a cell balance function.
A: 4s lipo battery pack assembly requires very high skills. Below are the steps to DIY 4s lipo batteries:
First, design the 4s battery lipo construction and choose the correct type of lipo battery cells, PCB for batteries lipo 4s, wires, and connectors.
Second, make sure that the 4 cells lipo batteries are in great consistency of 10mV voltage tolerance, 5mAh capacity tolerance, and 1mΩ to ensure excellent performance.
Third, assemble the 4 lipo battery cells in series, soldering PCB, wires, and connector with the battery packs.
Four,wrap 4s battery lipo with shrink PVC as surface protection. After assembly, test whether the battery voltage and internal resistance is normal.
A: 4s lipo battery consists of 4 cell lithium polymer battery cells in series to make 14.8V nominal voltage, 16.8V fully charge voltage and 12V cut-off voltage.
A: VTCBATT can make the best 4s lipo battery for you. The best 4s lipo battery should consist of well-matched cells, smart PCB with functions of safety protection and cell balance, good PVC shrink, and extra cell-balance connectors to protect the battery pack from damage.
A:The nominal voltage of 4s lipo battery is 14.8V.The fully charged voltage is 16.8v. The discharge cut off voltage is 12V.
A:Yes.4s lipo batteries are wired in series.
