As an industry leader in the manufacture and sales of RC batteries, Ovonic has launched the Rebel series of batteries for Arrma RC cars, which means “Dare to innovate”. What are the advantages of Rebel batteries? High C-rate——Rebel series batteries use high-energy-density cell materials with lower internal resistance and higher C-rate, which can increase the …
Landing according to battery voltage Warm reminder from OVONIC, you can refer to the data of the battery indicator as to the usual standard: when flying to a voltage of 3.3V, the red light starts to light up, it is recommended to land, and there is still a certain amount of power reserve, so the …
According to statistics, the service life of a normal fpv battery is about 150 cycles, but there are also have some batteries that lose power after less than 100 cycles due to the incorrected used Therefore, the battery must be well maintained. Of course, the specific situation still depends on your usage habits. When you …
First, let’s take a brief look at Ni-MH batteries 1.Memory effect of Ni-MH battery NiMH batteries have the same memory effect as Ni-Cd batteries, but are much smaller than Ni-Cd batteries. Therefore, it is not necessary to perform a discharge operation every time it is charged (because improper operation will damage the battery), it only …

Graphene is a honeycomb flat film formed by sp2 hybridization of carbon atoms. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monoatomic layer graphite. Its thickness is about 0.335nm, and there are different undulations depending on the preparation method. Usually the height in the vertical direction is …

High temperature is the worst enemy of batteries, including lead acid. It is said that adding temperature compensation to the lead-acid charger to adjust for temperature changes can extend battery life by 15%. For every degree of temperature increase, the recommended compensation is a 3mV drop per battery. If the floating voltage is set to …

First of all, what is 2s, 3s, 4s… Let’s start with the most essential difference. Simply put, they are all multiples of a single lithium polymer battery, and they are connected together to form a higher voltage battery. If two batteries or batteries are connected in series, the voltage will increase; 2S battery means that …

Lithium polymer batteries (lipo batteries)store a lot of energy. It is still nowhere near that of an equal weight of petrol but it’s much higher than any other battery. The result is that a failure or short circuit can result in a catastrophic fire or even a small explosion. Charge Lithium polymers shouldn’t be left unattended …
