3.7V 1S Lipo Battery Manufacturer in China
1S lipo battery is a type of rechargeable lithium battery, consisting of one single 1S lipo cell and built-in PCB against overcharge,overdischarge, overcurrent, and overtemperature. The 1S lipo battery has a nominal voltage of 3.7V, a max charge voltage of 4.2V, and a cutoff voltage of 3.0V.
VTCBATT can customize the 1S lipo batteries into many different types of sizes, shapes, discharge rates, and temperatures as per the specific requirements for different appliances. 1S battery lipo is normally provided with Molex, JST and Hirose different battery connectors to allow quick plug.
1S lipo Battery Manufacturing Process
VTCBATT adopts high automation and strict quality control in the 1s lipo battery manufacturing.From raw materials to final battery pack,the 1s lipo batteries are strictly controlled in 2000+ key factors and conducted various strict safety tests to ensure the most safety and reliability of the 1s lipo batteries.
PCB Part List
VTCBATT insists on using the Seiko IC for the 1S lipo battery, which has the most accurate protection and fast response time. Furthermore, Seiko IC is anti-interference to avoid any power failure cause battery damage.
Long Cycle life
Composed of a 100% LiCoO2 battery, 1S Lipo Batteries produced by VTCBATT can still maintain above 80% residual capacity even after 500-1000 cycles. Compared with other LiMn2O4 and NCM raw materials, the 1S lipo battery composed of 100% LiCoO2 batteries is much more durable, long-lasting, and powerful.
Low self-discharge rate
VTCBATT-branded 1S lipo battery has 3% low self-discharge rate, which can avoid over-discharge after long-time storage. Even after 60 days of storage, our battery can still keep around 93% capacity.
Successful 1S lipo battery projects
VTCBATT already delivered tens of thousands of 603450 1000mAh 1S lipo batteries installed in thousands of smart homes in Europe, facilitating people’s daily life in curtain control, home light control, temperature control, and smart audio devices.
Cooperated with the branded fetal doppler manufacturer in Israel for 5 years in supplying the 3.7V 503450 900mAh 1S lipo battery. The 1S lipo battery always delivers stable, reliable, and continuous power to care for the infant’s health and relieve the anxiety of the mom-to-be.
After 6 years of cooperation, VTCBATT produced tens of thousands of 3.7V 22Ah and 3.7V 27Ah 1S LiPo batteries to track the cargo container and automatically charged by solar panels.VTCBATT battery can power the cargo tracker for 10 10-year lifespan.
A: Use the specified 1s lipo battery charger with max 1C charge current in CC/CV mode.
The charger will end the charging current automatically when the current reaches 0.01C.
A: 1s lipo batteries should be 50%-60% SOC charged before storage.
Only keep the batteries at room temperature 20°C-25°C.
Keep the 1s lipo battery in cool and dry places.
A: Yes.You can charge the 1s lipo battery on USB charger,which should be in CC/CV charging mode and end at the charging current less than 0.01C.
A:If you will store the 1s lipo battery,you don’t need to discharge it.Because the battery has self discharge rate,fully discharge will cause the 1s lipo battery overdischarged.
A: Before multiplying the 3.7V 1s lipo batteries,you need to understand whether you need to increase the battery voltage or battery capacity.If you just want to increase the voltage,then you can connect in series.If you want to increase the capacity,you can connect in paraleil.
A:In consideration of long cycle life and safety, charge the 1s lipo battery at standard 0.2C/0.5C charge current or maximum 1C charge current.
A:For 1s lipo battery in parallel,you just need the charge the final paralleled lipo batteries as one complete large battery pack.But before charging,you need to fully understand the capacity after parallel. Only charge the final battery pack at max 1C charge current,trickle charge current is better.
A: For voltage and resistance test,you can use the normal multimeter.
But for exact capacity test,you need to use the comprehensive battery tester machine to fullu charge and discharge the battery.
A: 1s lipo battery is a type of rechargeable lithium polymer battery in one single cells integrated with PCB together.Its nominal voltage is 3.7V,max charge voltage is 4.2V and cutoff voltage is 3.0V.
A: Before charging 1s lipo batteries,you need to fully understand the battery capacity.
Choose the specified charger with max 4.2V charge current and CC/CV charging mode.
A:Use the specified 1s lipo battery charger with 4.2V max charge voltage.
Since 150mAh capacity is small current,you can only use max 150mA current to fully charge the battery.
A:Before storage, keep the 1s lipo batteries with 50%-60% SOC.
Store the 1s lipo battery at cool places with only 20°C-25°C.
1S lipo battery only has one single cell and no need for balance cables.
