I'm in Asia where ebike are everywhere. I have one that has 5 12v 20Ah batteries so 60v/20Ah. The motor can handle 70v. I want to increase the range with 60Ah batteries.
See below my battery specs. I plan to connect 17s for 4.2*17=71.4v maximum voltage. I'll charge to 4.1 only for 69.7v...
Charging lithium-ion question. I know I need to charge away from my house.
A certain scenario keeps nagging me. With respect to CC then CV charging, is it possible to do it manually if one has a PS that has adjustable voltage and current settings? I'm not saying I would do this, but if...
"LED with a driver" I agree. I've taken apart more than a few LED bulbs and I always see a step down voltage converter.
"Bare wire" That would work. Just need a way to keep the wires separated. Not sure that's very easily done though.
I found this:
"As an electrician for over two decades, I get one question asked a lot; what is electrical arcing?
To put it simple, electrical arcing is when electricity jumps from one connection to another. At times you hear electric switches producing a sizzling/ cracking sound...
"temperature rating of the type of insulator" interesting. so the insulator is selected with heat in mind and amps are heat. I will try it on a prototype and see what happens. Leave it on for a few days outside our house. See if the insulator melts away or if the volt meter can measure any...
Household electric isn't difficult. I was just wondering why the wire I mentioned is rated at 30 volts. A recessed light fixture has very small wires that carry 230 volts. So you are saying, the wire in the fixture has a different coating than the 30 volt sprinkler wire that I noted. I'll...
I have a basic electric question. Sprinkler wire is usually 18 gauge and I saw on Amazon that the label says 30 volts. Does it say 30 volts based on using it for a sprinkler system? Maybe those systems operate in that range? I want to power 230 volt very low wattage LED light bulbs with the...
Right, it isn't clear. I put a question on Renogy's forum just a few minutes ago. I hope I get an answer. If I do, I'll post it here.
I did set the battery type to Li and the voltage to 24v. I think JWLV is implying the adventurer will double any related 12v value to 24v in the background...
It is in a concrete structure.
The PS is high quality actually and keep in mind, I charge and then wait for the next brownout which could be months away so I won't have to charge much.
I'll try to find what boost voltage means for this charge controller when lithium-ion is the battery type...
"According to the manual, for 24 volt systems, this needs to be entered manually to work."
The manual says:
Press “SELECT” to change the Boost Voltage. The default setting is 14.2V and the user is able to set it in the range 12.6~16.0V, with a step of 0.2V.
I don't know what Boost voltage is...
I'm not using panels to charge. I'm using a DC-to-DC power supply since all I want to do it use it for backup power during a brownout (some lights, CP, laptop). Power supply will output 60v but CC only takes 50v max.
Can I charge a 24v lithium ion battery with this CC?
On Amazon, it says this about the product:
12V/24V Automatically Detect Automatically detects 12V or 24V DC system voltages (for non-lithium batteries). The LCD screen and multiple LED indicators display the solar charging and battery...
