    Simple regen design

    I drew this simple circuit to use a motor as a regen for a motorbike. It would use diodes that I would be able to turn on or off manually. It is a hybrid so there is also an engine. A voltmeter would used to monitor the battery voltage because there is no regulator. Do they make simple...

    solar CC with motor generator?

    Yes, it is. I cant quite figure out the alternator, but I'm playing with it. Now I'm trying a motor. All I want to do is make a simple bike generator. Does anyone know an easy setup?

    solar CC with motor generator?

    I wanna use a 24V motor to charge a car battery. Can I use a solar charge controller?

    How much power to field coils?

    Awesome, more good info. Well I tried to post a photo. I think theres only one field coil. And I found the diagram, here, also attached. For now, this is going to be a human powered bicycle generator and yeah, Im guessing it will be like 300W max. Anyway, I found some more stuff on the...

    How much power to field coils?

    OK, well, learning some new stuff here. Pinouts, thats the word I was looking for! Not sure what plural field coils are? Attached is a shot of the schematic, let me know if you need more.

    How much power to field coils?

    Yes, I read it. I've read other stuff on it too, including a textbook. Still none of it has answered this question.

    How much power to field coils?

    Still dont quite understand. I'm not really clear on alternators yet. As I understand it, the field coils are used in place of permanent magnets (wish they would have just said that in tech school). And the computer can vary the voltage to the coils to change the output current right? So...

    How much power to field coils?

    I'm using a PCM controlled alternator. And it is internally reg/rec, so nothing to worry about there. It will be hooked up to an SLA an then an inverter. I've seen some other people use AAs for the field coils. But which electrodes do I connect to? Can it be connected continuously? And if...

    How much power to field coils?

    I'm building a generator using a car alternator. I can't seem to find out how much power I need to supply to the field coils or any other details around that. The alternator has a four prong plug. Any help would be great!

    Charging question

    Ive got a standard 36 volt hoverboard lithium battery pack with BMS. Its for a bike so i dont have anything other hoverboard parts. I think the normal charger works through the control module. Can I use the charger thats built for it? What about alternatives? AC adapter? I also have a...

    Homemade charger

    They are Li-Ions. I have a basic electrical training, chargers are a little beyond me. Can you just explain everything I need for this to work?

    Undervolting question

    This is actually for a bicycle hub motor. I'm looking into buying a front wheel kit. I would like to get a 24 volt system because I want to use SLAs and I only want two. But I haven't found very many of them for a low price, especially because shipping is high because a lot of what I have...

    Undervolting question

    Would that setup be slower than or the same as a 24 volt system and 24 volt motor?

    Undervolting question

    Is it safe to run 24 volts through a 36 volt system? What about controller?

    Overvolting Razor E300

    The E300 has a 24 volt system, two 12v SLAs, and my question is whether I can overvolt with 6 more volts. Or even 12 more. Will it confuse the control module or not? Also, will it affect range?

    Battery wiring

    I don't quite follow all the terminology there, but it seems like it would cause a problem having different capacities linked in series. They would both charge and discharge at different rates? I'm guessing if both capacities were equal, then it would all work. Does that sound right? I'm...

    Battery wiring

    I have a Razor E300 scooter. It's a 24 volt system-two 12 volt SLAs with a wall charger. I'm pretty sure I should be able to add another battery in parallel with one of the existing batteries, right? It won't have any problem charging the extra one will it?

    Homemade charger

    Sounds like it might be more work than it's worth, but I appreciate everyone's input. I think I'll just stick to a simple hybrid: gas power with an electric assist.

    Homemade charger

    OK, apparently it's harder than I thought...in that case, what is the simplest way to hook up some kind of mechanical charger? Here's the ultimate goal-I just bought a Razor E300. 24 volt system (pair of 12 volt SLAs) and I'm going to attach an engine to make it a hybrid. If it's too hard...

    Homemade charger

    Hi guys-I want to make a homemade charger using a DC motor. I want to keep as simple as possible. It's for a 12 volt SLA. I don't know much, but I was thinking of something with a Zener diode in there for regulating?
