What amount of current should I use to charge a 12V car battery?
The normally recommended maximum charge rate is C/4 to C/5, ie. 1/4 to 1/5 of the battery capacity in Ah. If your battery capacity is 90Ah then 30A is C/3.

Battery Capacity: This value can usually be found printed on your battery. The greater the number, the more energy the battery stores. The greater the number, the more energy the battery stores. If the capacity is stated in Ah (amp hours) you can convert from Ah to mAh (milliampere-hours) by multiplying by 1000.
3S Battery
Remember, states of charge in any battery are based on capacity, not voltage for the simple reason voltage drop in a battery is non-linear. Link I always assumed the 80% rule was 80% of the fully charged voltage, so a 3S battery (12.6V fully charged) would read 10.2V when fully discharged. Apparently this is WAY off.

It will do 300W but that should be limited to a few seconds. However if you''re hovering a multicopter, 150W may cause them to heat up over a few minutes.

The powerplant is the same as a piston airplane. The R-22 has a Lycoming O-360. Where the difference comes in is the drive system.

Balance charging is good to do, but it''s important to know the fast charge setting isn''t more damaging to the pack than a normal charge. Fast charge simply omits the last constant voltage cycle, ending the charge when the cells first reach 4.2V, which provides 70-80% usable capacity without waiting for the slower constant voltage cycle to complete.

Current State of Charge: The current state of charge indicates how much energy remains in the battery. A deeply discharged battery will require more current to reach a full charge. For example, a battery at 50% charge may take longer to charge than one at 75%. The rate of charge can be affected by the specific charging cycle being used.
6 Frequently Asked Questions about “How much current should the fixed-wing battery be charged with ”
What is the difference between a fixed wing and a multi-rotor UAV?
On the other hand, the multi-rotor UAVs have rotor systems generally carrying three or four propellers that are capable of vertical take-off and landing (VTOL) and hovering over an area while carrying sufficient payload. In addition, they are more maneuverable than fixed wing UAVs with the ability of quickly transition from hover to cruise flight.
What voltage does a UAV battery need?
The electrode pairs determine the voltage ranges a battery can provide. For LiPo cells, this is approximately 4.5V to 3V. However, these voltages aren't usually adequate. The UAV's electronics need a constant voltage to function, which can exceed 4.5V. More importantly, the motors need a higher voltage (as described previously).
What are the performance criteria of a battery?
Voltage, capacity, energy, specific energy and energy density, self-discharge, number of cycles, temperature are the performance criteria of batteries . These types of batteries are preferred due to their long lifetime, affordability and they can be used by recharging between 500 and 1000 times on average.
Are rotors more maneuverable than fixed wing UAVs?
In addition, they are more maneuverable than fixed wing UAVs with the ability of quickly transition from hover to cruise flight. However, the horizontally mounted rotor system is placed at the wings or the body that results in an enormous increase in drag force opposing the cruise flight.
Does the sizing procedure provide reasonable design in terms of battery-pack weight?
The results show that the sizing procedure provides reasonable design in terms of battery-pack weight with respect to total aircraft weight only if maximum endurance is the design goal. Conversely, when maximum range is pursued, the best design for the same payload is characterized by a higher weight, with a modest range increment.
How many power levels does a battery have?
In the first set of experiments, the battery is discharged at 4 different power levels, namely 50 W, 100 W, 200 W, and 300 W, starting from a fully charged condition.
