ok. parts ordered! 20 mosfets, and 10 of everything else. havent got lights or switches yrt though. but i did buy a soldering iron, and a multimeter.
depending on the price of the lights, this kit shpuld be a decent price! cause for 20 mosfets and 10 of everything else sept switches, my order came to 37 dollars!
Not bad! One thing I just thought of, that might benefit people in the future. A
14-DIP Socket would probably be a safe purchase to make. Basically, it lets you do all of the soldering away from the actual IC pins, directly on the socket's pins. Then when you're done soldering to the DIP Socket, you just plug in your IC to the top of the socket, and fire 'er up. It reduces the potential for frying the IC.
hey rock what do ya think of this as a always on charger, to use when i am riding the bike, so it will be a fairly even discharge? take some put some in kinda deal. would that even work without frying the setup? that way i dont gotta pay for a charger.

Hmmm. Well, it's important to keep in mind that that is designed to be a generator, not a charger. Basically, that means that, when you're moving at a fast enough rate of speed, it should be outputting ~12V. Because power(W)=current(A)*voltage(V), we know that it is spec'd at a current output of 0.5A (theoretically). For normal SLAs, you really don't want to go much past 2A for charging (faster rates generally degrade the battery's ability to hold charge), so this is an ok current level.
The main problem is that the voltage output of the generator is too low. For even the slowest trickle chargers, you need at least +13.5 V to really be able to charge the battery. Consider this - if your generator outputs +12V, and your battery is running at, say, +12.1V, current is actually going to want to flow from the battery into the generator, as opposed to the other way around.
Another thing to consider is what the generator's impedance is. Basically, when you're not running the bike or the generator, and it's hooked up to the battery, can current flow from the battery "backwards" through the generator? They may have taken this into consideration when designing the generator (using diodes, etc.), but they may not have. If not, you'd actually be
draining your battery when the bike isn't running.
Basically, unless you want to run the risk of harming your battery, I'd either look around online for schematics detailing other peoples' SLA charger designs or buy a charger.
