Hello everybody,
I am new to this forum/Hobby and have a question in regards to charger math.
So I am looking into to buy a Hota d6 plus as many here have recommend and it seems to fit my needs.
I just would like you all's opinion on if i did my math right.
I have two of these Batteries.
So I figured that at 1c charging rate i will need to apply this math,
Watts = Volts * Amps
charged voltage 16.8 x 9=151.2 x 2 batteries = 302.4w
storage voltage 14.8 x 9=133.2 x 2 batteries = 266.4w
(not sure to use the charged or storage voltage to apply)
The Hota D6 plus has and output AC of 300 watts.
This is cutting it more than close since chargers have usually an efficiency of 80%
300w/0.8%=375w
which is not enough to charge at 1C if i understand this correctly
So i am thinking to get a 24v DC power supply and i did my research but i just would like
to get everybody's input.
Mean Well RSP-1000-24/ 1000 watts, 42 amps, 24 volts
Hota charger output max DC 650
charger efficiency 80%
[email protected]% efficency = 812.5w draw from the power supply
I chose RSP over the SE model with the same Wattage because of PF which is on average 0.6%
in the average household, this gives me a little wiggle room if i decide to charge at maybe
1.5C or get into 6s Batteries.
Please let me know what you all think, if i missed something.
Every comment is appreciated.
Thank you
Pete
