Below is the different voltage table.
| 8S battery lipo | Nominal Voltage | Max charge voltage | Cut-off voltage | Storage Voltage |
| Voltage | 29.6V | 33.6V | 24V | around 30.4V |
Normally XT60, XT90, Hirose, T-plug, and EC5 connectors are widely used in 8S lipo batteries.But VTCBATT can use a customized battery connector for 8S battery lipo.
Use the specified 8S lipo battery charger as per the datasheet.
(1) Correct charging voltage
The 8S lipo battery charger voltage should be 33.6V for 8S. Higher charge voltage will damage the batteries.
(2) Cell Balance Function
The charger should have a cell balance function to ensure each cell is consistently charged.
(3) Correct charge current
The charger current should not exceed 1C current of the 8S lipo battery’s capacity.
(4) Correct battery chemistry
Different lithium battery chemistries have different voltages; ensure the charger you use is specifically designed for LiPo batteries.
(5) Temperature Control
The smart 8s battery lipo charger normally has automatic temperature control functions to cut off the charging if over a certain limit to ensure safety.
8S Lipo and 4S Lipo have different cell numbers. Besides the same lipo battery chemistry, their voltage is different.
| Cell Number | Nominal Voltage (3.7V per cell) | Max charge voltage (4.2V per cell) | Discharge cutoff voltage (3.0V per cell) | Storage voltage (3.8V per cell) | Application | |
| 8S LiPo battery | 8 | 29.6V | 33.6V | 24V | around 30.4V | Large drones,heavy-lifts,large scale RC boats,E-Bikes,E-skateboards |
| 4S LiPo battery | 4 | 14.8V | 16.8V | 12.0V | around 15.2V. | Mid-sized drones,FPV,RC boats, |
8S Lipo batteries are widely used in Large drones,heavy-lifts, large-scale RC boats, E-Bikes, E-skateboards.
Many factors affect the life of 8S Lipo battery.
- Temperature
High temperatures will accelerate the aging of the 8S Lipo batteries.
- Cell Consistency
If the cells are not strictly matched, the 8S lipo battery can’t be fully charged and fully discharged, which shortens the life of the 8S battery lipo.
- Charge&Discharge Deep
Fully charge&discharge will shorten the battery lifespan. Charge the battery below 20%-30% SOC.
- Battery BMS
Use the battery BMS with cell balance functions and over-temperature monitor!
The BMS will charge and discharge the cell in balanced methods and cut off at over-temperature.
- Correct Charger
Choose the right 8S lipo battery charger with balance charging, temperature control.
6S lipo battery is more popular than 8S lipo battery. But a lipo 8S battery is for niche projects. 6S lipo batteries deliver a stable 22.2V nominal voltage, satisfying most drones and RC toys. Furthermore, most systems are designed in 6S 22.2V voltage to deliver suitable burst power, controlled speed and run times. The most important reason is 6s lipo battery is cheaper than the 8s lipo battery.
You need to consider below factors for storage.
(1) Voltage
-Before storage, keep the lipo battery 8S at 3.8V-3.9V. For long-term storage, periodically charge the battery and keep it at 3.8V-3.9V to extend storage.
(2) Environment
-Store the battery in a cool, dry place with a temperature range of around 25°C.
-Keep away from flammable materials.
-Avoid humidity.
-Place a class D fire extinguisher near the storage/charging area.
Storage Safety Caution.
- In case of fire, you can use water to cool a burning LiPo battery, but sand or a fire extinguisher is better to smother it.
- Use electrical tape to cover the main power connectors to prevent short-circuits.
- Check the physical damage-puffing, swelling, dents, or tears. Don’t store the damaged batteries and dispose of them correctly.
There are main four reasons for the rise of lipo 8S battery.
-8S lipo batteries deliver high voltage 29.6V platform, offering balance at current reduction for a certain power level.
-The technology evolution of ESC,motor,and chargers to enable the 8S battery lipo performance.
-The large-scale RC and big drones rapidly demands in the market.
– Battery Technology upgrades supporting the cells in high consistency and high drain current.
Generally, there are two phases for the 8S lipo battery development.
First phases, from 2014 to 2016, Lipo battery 8S are niche-made for large-scale RC and drones to achieve high performance.
Second phase, from 2016 to 2020, the Traxxas X-Maxx launch greatly inspired the potential market of lipo 8S battery.
Now 8S batteries are widely used for standard high voltage tier and have become the mainstream types for the RC and drones market.
Lipo battery 8S means that 8 lipo cells in series configuration to make a total battery pack.For lipo battery pack,you can make the batteries in different series connection to increase voltage or different paraleil connection to increase the capacity.
The best lipo 8S battery should contain below factors:
| Cell Voltage | Cell Capacity | Cell Internal Resistance | BMS | Temperature | Connector | Cable |
| Cell tolerance within 10mV | Cell tolerance within 5mAh | Cell tolerance within 1mΩ | The BMS should contain a cell balance function | The battery pack should contain a temperature sensor | Extra cell balance connector, such as XT, Hirose, T-plug, EC5 | The cable should be strong enough to hold high current |
