    solar panel wired direct to a brushed motor?

    I have the solar panels but not the motor. The Craigslist trolling motor I'm interested in is $22 but it is in rough shape and also looks ancient. The 30lb thrust Minn Kota's maximum amperage is 30amps but I can't find amperage specs on the old 8lb thrust Minn Kota 10 that's currently on...

    solar panel wired direct to a brushed motor?

    Would it be a bad idea to run raw solar amperage direct from panel to a brushed motor; no esc, no solar charge controller, no battery? I've gotten into multi-day kayak touring and I have a decently efficient boat but the possibly hairbrained notion of a solar panel assisting with overall effort...

    Understanding and Using EGO Power+ Batteries

    I finally transitioned off hobby lipo batteries to a "safe" battery and now I'm rockin' the weed-whacker batteries with EGO Gen3 5ah x2 and TerraFirma adapters (10ah total). Do a little yard work, do a little e-biking all on the same battery. For what it's worth the LVC trips on my batteries at...

    One stop for solar charging ebike info?

    I set up a camping trailer for hauling all my stuff that way I can keep my e-bike uniform/clean when I'm not camping. For day trips I think it better to simply haul around more battery with you but I much prefer charging at the camp site on multi-day trips over trying to find an open outlet at a...

    questions about mini-hub for a child

    Thanks amberwolf. That's got my mind steered in the right direction with thermal control modules and voltage divider. Escs just hear "voltage" from your ebike throttle correct? Like your throttle is just a fancy potentiometer that changes the voltage from 0 volt to 5 volts or something like...

    See a lot of inexpensive brushless hub motors nowadays (hallomotor etc) are these any good?

    Does anyone know the actual weights of these Hallomotors? Every motor is listed at "5.8kg".

    questions about mini-hub for a child

    Hi, I've been out of the "buy new stuff" game for quite a while now. I have been riding my most recent build since 2013 and nothing has broke. I'm afraid I've lost touch with what's the latest-and-greatest. 1) I want to do another build, this time an "assist" based build, the lightest possible...

    Razor kart upgrader

    Seems like an "escalation of force" problem. I mean sure you can upgrade the motor, but then you should probably upgrade the axles and then you probably don't want that much stress on the wheels/tires so upgrade that too, then the brakes won't stop you fast enough, then the ball joints ect ect...

    preferred method for stacking batteries end to end

    Right. For typical 5 minute "sporty" flights I like a good 30-40c, for 30 minute flights I want about 10c and for 1+ hours flights I only need 5c. For my intended use 3c is plenty fine. It will be 10 amps maximum draw and about 2 to 3 amps cruise on a 10ah battery. That would be 0.3c draw...

    Build 5: Black Bullet- KMX Typhoon Tadpole Trike

    Electric bikes were put into their own separate category which is fine with me.

    Build 5: Black Bullet- KMX Typhoon Tadpole Trike

    yeah a good 20 minutes faster than the 2nd place rider lol, I just couldn't help myself. "You are going to burn up your battery trying to go faster than us on the hills" "your motor will break if you try to keep up" "you should start in the back so you don't interfere with the 'fast' riders"...

    preferred method for stacking batteries end to end

    Sorry I was thinking 3s 10ah. I'm into both electric bicycles and model airplanes. It would be for a long-skinny fuselage. For model airplane weight reduction reasons I probably won't be doing a full-length PVC sleeve but I like the idea. The lightest option seems like the solder tab (with...

    Hub motor industry dying?

    Hey, that's not true BBS02 = 10lbs BBSHD = 13 lbs Cyclone kit = 16lbs. 9c/mxus hub = 13 lbs. The weight is comparable because a certain amount of magnet and copper is needed to accomplish the same task. That's not true BBS02 = $450-ish BBSHD = $700 Cyclone kit = $350 9c/MXUS = 300-ish...

    preferred method for stacking batteries end to end

    I think I want to build a 2170 pack except stacked end to end like in a flashlight. What is the current best way to build packs like this?

    Hub motor industry dying?

    In regards to America vs Europe it should be mentioned that American infrastructure is built up around highways and European infrastructure is built in regards to horse/foot travel only to later adapt motorized use. Americans can and do hop in their car and drive 3000 kilometers to see their...

    Hub motor industry dying?

    In paragliding there is a definite "bell curve" of PG injuries. The beginners generally tend to be very cautious and the experts know the sport well enough not to get hurt. This tendency is known as "intermediate syndrome". While I know intermediate syndrome as particular to air sports, I don't...

    Solar Trailer Technical Advise

    Depends on the panel. I was pleasantly surprised to see my HQST 50w "flex panels" giving just a little more than 50 watts (measured at the wires)

    Solar Trailer Technical Advise

    I guess that sort of depends on how many whs you want to consume per day. I personally find myself creeping into the 2k per day mark at times. You won't get a full 100 watts out of that trailer during the morning and evening which is probably the time you want to charge. I would expect maybe...

    High powered Ebikes high speed suspension setup

    The bike will "porpoise" if your shocks are too soft. You don't want to be leaning way forward after your wheel drops down deep in a dip. The bike will slam and try drive a bike up your innards/through your forearms if the shocks are too hard. Generally you want the shocks soft for casual use...

    Advice for a newbie

    Due to their more robust frame downhill and freeride bikes make the best bikes for what you are talking about. You can probably find a used one on Craigslist. You could put a large hub motor on the rear wheel but having single-tracked on both hub and mid-drive I find mid-drive to be better...

    Build 5: Black Bullet- KMX Typhoon Tadpole Trike

    Ok, I have done several test runs of the Skull Valley Loop with the Black Bullet now. With 17lbs of lithium I'm hitting around 2:30 With 24lbs of lithium I'm hitting around 2:15 With 26lbs of lithium I'm getting just under two hours I guess the question now is should I leave the athletes in the...
