How To Charge Lipo Batteries In The Field. However when you charge them fully to 4.35v per cell you get the following advantages: Gotten into the habit of doing a storage charge on the batteries after each flying session since i always bring my charge setup with me to the field.
For safety, lipo batteries are often recommended to be charged at no more than 1c. But you need a charge controller capable of charging the battery accordingly. For example, if a parallel charging board has 5 ports and 5 batteries are connected, then the current coming from the charger is divided into all the 5 ports.
Lastly, even though you can charge at higher rates these days, i recommend always charging at 1c.
For lipo batteries identify how many cells it has by reading the label and comparing it to the number of wires on the balance plug (in our case three wires = 2 cell ). I use a jump starter as a power source for charging at the field. With a fully charged hvli battery, voltage is higher than normal lipo’s (on a 4s, hvli is 17.4v, lipo is 16.8v), therefore your motors will run. Lastly, even though you can charge at higher rates these days, i recommend always charging at 1c.
