Re: New Lipo accidentally discharged to 2.6V

Yesterday had a ride with that friend and the left side of his frame open and everything looks good, performance is insane (nasty acceleration...) Does it really take one time while they are brand new to damage them? I can not stress this enough, yes! However, the battery is above 2.5v so the risk ...

Re: New Lipo accidentally discharged to 2.6V

I recommend putting somewhere outside and away from anything you don't wish to part with if you plan on charging it. 2.6v is salvageable if you can set a lipo charger to trickle charge it at 0.1A until it gets to 3.2v.

I perfer just to overcharge it until it explodes 8)

Re: Replacing 16 inch front Wheel with New Electric Wheel

Hi Sorry if this is already posted. I checked but cannot find similar. I want to replace a standard 16 Inch wheel with an electric wheel on a kick scooter. The problem is all searches for scooters turn up moped type scooter results mostly and wide tyres with cast rims. So I'm posting this is the bi...

Re: running battery without BMS given incomplete charge/discharge

RC lipo has strict rules of management. You don’t need a BMS, you must be constant with the rules. The first rule: Never let RC lipo charging out of your immediate presence, unless they are in a 100% fireproof enclosed area. The 2nd rule: RC lipo must sleep about storage voltage and unplugged off a...

Re: Another Stealth bomber (clone) build

@sirlongass, I made them on the mill pretty quickly. I Milled out a pocket on the back side so that I can still run the washers in the dropouts (they actually put pressure on the washer keeping it engaged in the dropouts) and the clamping bolt in the back of the swingarm. I just got my moto seat an...

Re: Another Stealth bomber (clone) build

How did you make those torque arm plates? Also, I find the moto seat that you can get from em3ev is a little uncomfortable after a long ride. I might end up welding a new seat frame for my electric enduro. https://delfastbikes.com/front-end//img/delfast_top.jpg Something like this. It's from delfast...

Re: Max Discharge Current Explanation Needed

If it can be done, buy a battery with a constant discharge current higher then what your ebike can is rated for. Where do i find that rating? the motor controller? or is it based on the wattage? If you are building your own battery, use the manufactures specs for charging and discharging. If you ar...

Re: My (almost)complete Electric Enduro

I think shipping n the battery (and seat) was like $150 and that includes everything, not extra taxes or BS. Did you buy those axle covers? Or did they come with the frame? Can you post a close up pic if you have time? http://i65.tinypic.com/2aj97bt.jpg The plates come with the frame. I think they ...

Re: Max Discharge Current Explanation Needed

There are usually two ratings when it comes to Discharge Current. Constant discharge current: The amount of amps you can pull from the battery for any amount of time with no chance of damage. Max/Peak discharge current: The max amount of amps that can be pulled from the battery without doing instant...

Re: Snapped axle on Crystalyte TC100 hub motor, almost died

I don't think that's true at all. I work on all kinds of rusty bikes with all kinds of high mileage, and rust has not caused them to break. This is the consequence of bad, lazy, cheapskate design and poor manufacturing, and nothing else. Rust makes fasteners stick, sometime permanently. It's ugly, ...

Re: New ebike build!

Of course you could get a higher wind for more torque but I'm unsure if that would be enough. Now if your talking about running 2 hubs, it would definitely have enough power and both motors would help each other. You can run them off two batteries or one. Both work but you still need a controller fo...

Re: Snapped axle on Crystalyte TC100 hub motor, almost died

I don't wanna sound like a dick but this is what happens when you aren't doing checks/maintenance. The rust was clearly visble outside the axle and if I saw it on my bike's axle, I'd be very suspicious.

Cool man. I dont know what your set up was so I just instantly recomended it. Powerful D&D hubs can be simple if you've got the right rear dropouts to fit one. Now, you could use the Mxus 3000w at a lower level but I'd recommend not running it lower. Reason being is I actually own a scooter that...

Re: New ebike build!

Honestly, I think you should go with a mid drive. Something like a 1000w bafang. Especially if your going to be towing something around plus going up hills! Now because a mid drive works off the chain and gears on your bike you can use a lower gear for going uphill instead of having your hub motor t...
