Re: Increasing range on a Bafang 750.

Remember that "all" the current draw from the motor is going through that type of meter. This is why they use heavy cabling. Depending on the gauge of the extension wire you used it could be very undersized for that motor. Running my 750 on my fat bike at 15mph I consume about 2.25ah "without and pe...

Re: Increasing range on a Bafang 750.

I have 750 Bafangs on 2 bikes. The first is a converted EZip. The second bick is a cheap Mongoose fat bike. IT is equipped with a California EBike fat bike 750 Bafang. Both bikes are equipped with a battery mount so I use the same pack on both bike. The pack is a 48v 11.6ah Panasonic Li-ion pack. Pl...

24/36v Using a 48v controller

I want to build a trimmer for the side of my tractor. What I have seen on the pre-made market is pure crap. I bought a 12v to 36v brushed motor. My intention is to use existing components for everything else. I have a 48v x 11.6ah li=ion pelican pack, 48v x 50a brushed controller and half twist thro...

Re: How long should a new pack keep full voltage?

I can't relate to weather you have a true problem or not. But I'm curious why are you full charging a pack just to let it sit for 2 months? This is a no-no for pack longevity. When the pack is not expected to be used for long periods it should be discharge to around 50%. At least that's my understan...

If you honestly think you could do a better job selling in a market where everything is already cheaper on ebay, give it a try. Until then, nobody likes a whiner, so keep it to yourself. A whiner, really? I'm not trying to say anything bad about Luna because I've never dealt with them. But obviousl...

Re: hook a cell phone up to my e-bike battery

The BEC i showed in the picture is capable of outputting 7amps. I presume that would roast the socks off a cell-phone. :twisted: Does the cell phone dictate the amperage draw or does the charger itself regulate the amperage output? That's a question I've always wondered about. Do all/some cell phon...

Re: LifePo4 Voltage Question

Keep in mind almost no supplier gives the true pack rating. Just as a 12v lead battery is actually dead when it get to 12v. Supplies use different voltage for cells when rating the total pack voltages. Some use the true usable voltage of Lifepo4 cell which is generally 3.2v * ? or the max recommende...

Re: Best method and switch for multiple battery setup

I've used OEM switches from EZip bikes as on/off power switches on 48v bike setups. They have the bottle blade connectors your looking for and are on/off/on switches. They are a panel type switch which is nicer to mount. They cost around $10 each and can be found anywhere EZip bike/parts are sold. I...

I got mine delivered last week but I haven't been able to install it. The programming cable that Luna sells works fine but setting the current above 30 produces an error. The motor really looks like it can support more than 1500 watts, Now that I have it with care I even think the nylon gear will h...

I think I saw them a long time ago on the "Shark Tank" TV program. They were of course looking for investment and publicity. Don't remember who or if anyone invested. But I think they walked away happy. Have to wonder if that's how that came up with the name.

Re: New Bafang Crank-Drives

Intelligent shifting is a given. :) The controller should be able to protect itself though, so why doesn't it? I still believe some failures are related to too small input capacitors.

If this were true then the load on a single cell would be about 27a. High but not a kill...
