What should I charge for 4S LiPo?

LiPo 4S batteries consist of 4 LiPo cells connected in series, hence the “4S” as part of their labels. Each cell features a nominal voltage of 3.6-3.7 volts (mostly 3.7 volts), a maximum charging voltage of ~4.2 volts, and a cutoff voltage around 3.2 volts.

Are LiPo AC or DC?

If you’re running 2S LiPo, most AC chargers will do what you need. Where you really start needing a DC charger and power supply is if you are running higher cell counts (3S and up). If you have an AC charger rated at 50W you can charge a 2S LiPo at 5.95A (50W/8.4V = 5.95A).

How many C can you charge a LiPo battery?

Max Current Draw = Capacity x C-Rating For example, if you have a 3S 1000mah 20C LiPo battery, the safe maximum current draw would be 1000ma x 20C = 20A.

What voltage should you stop flying a 4S battery?

In a 4S battery, using this standard, overall voltage should not come to a resting state below 12 volts (3 volts X 4 cells). Personally, I don’t draw down my 4S batteries below 13.8 volts. Another cause of battery damage is drawing the battery down too quickly with long duration high throttle.

How long does 4S LiPo take to charge?

That charge rate would take 1 hour and 40 minutes just to replace the 5000mah, but, will take slightly longer as the charge rate slows at the end, and the cells are balanced. Assuming it’s a good pack, 1 hour and 50-55 minute would be a good estimate.

What voltage is a 4S LiPo battery?

14.8V
Battery Voltage This is sometimes why you will hear people talk about a “4S” battery pack – it means that there are 4 cells in Series. So a four-cell (4S) pack is 14.8V, a three-cell (3S) pack is 11.1V, and so on.

How many volts is a 4S LiPo?

Battery Voltage So a four-cell (4S) pack is 14.8V, a three-cell (3S) pack is 11.1V, and so on. The voltage of a Lipo battery pack is essentially going to determine how fast your vehicle is going to go.

What amp should I charge my LiPo battery at?

For the vast majority of LiPos, the Charge Rate is 1C. The equation works the same way as the previous discharge rating, where 1000mAh = 1A. So, for a 3000mAh battery, we would want to charge at 3A, for a 5000mAh LiPo, we should set the charger at 5A, and for a 4500mAh pack, 4.5A is the correct charge rate.

When can I stop flying after 4S LiPo?

Understanding Battery Voltage As 3.3V per cell is the lowest voltage, it’s good practice to stop discharging your LiPo further when it reaches 3.5V just to be safe. Note that when you are flying, the battery is under load, and so the voltage will sag.

When should I land my 4S battery?

You should land when you have used 90% of your battery capacity! At this point the battery should theoretically be at around 3.5V – 3.6V. You should not however, rely solely on “mAh consumed”. The data from a current sensor resets to zero when the power is disconnected, or when the FC restarts.
