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...

Okay. I will research that scenario for more understanding.

"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...

So max volts for the pack is 29.4 so boost voltage should be set to 14.7?

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...

"Can you turn the PS voltage down to 35 volts?" Yes. It is variable output.

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...

This is excellent. Thanks for all the pointers. I'll copy/paste this into my personal FAQ document. I really had a hard time seeing the inverter as a load and knowing what parameters to use to calculate wire size. For example, using your P=E*I from above and turning it into I=P/E is...

A wire size chart that I found was incorrect or I was reading it wrong. I can see on a different chart that #6 works at 50A for quite a long distance. My inverter/batt/SCC will be very close to each other. I also get that the OCPD should be 50A. I've watched a lot of videos and I never...

Bumping this up. I'm not sure how patient I should be for a reply. I just don't want to create yet another wire size post. Thanks.

I'm confused about wire size as well and constantly second guessing myself. Is wire size based on the battery or the inverter attached to the battery? I will build a 24v system and I have good lithium ion batteries that a friend gave to me which came in this form 60Ah battery paralleled to...
