Re: FS: LG HG2 Cells - 18650 Power Cells

Hi!

How much for 128 cells, delivered to 33905 (Fort Myers, FL)?
I understand if you would prefer not to ship, but, I'm hoping, it does not hurt to ask!

Thanks.
-Mark.

Re: Is this worth it? New 18650 Cells @1.75 each delivered.

Good points. Planning to purchase 12 batteries (approx $210 US) for 144 cells. Of which I'm hoping >120 cells in ok shape. After testing each cell (to check capacity/health) I'll build a(an?) 8s15p pack that uses the Torqeedo BMS. 8s15p Pack info: Nominal: 29.6 v (max 33.6v). Power: 39 a/hr (2600 ma...

Re: Anyone Ride on the road with a bike or cargo trailer?

I've been using a BOB for 5 years now. Camping, shopping, touring w/long-range battery packs ((54kg batteries + 25kg of travel stuff) - no handling issues). Most impressed/ recommend it. Adjusting the tire air pressure was the key to smooth towing. My bike is LW recumbent (Ryan Vanguard), possibly l...

Is this worth it? New 18650 Cells @1.75 each delivered.

On Ebay it would seem there are a number of 'New' Laptop batteries with 12 Cells for approx $21 delivered (within the US): Example: Title: Genuine Toshiba Satellite P10 P15 Laptop 12 Cell 6450mAh Battery PA3307U-1BRS: "Genuine Toshiba Satellite P10 P15 Laptop 12 Cell 6450mAh Battery PA3307U-1BRS Alt...

Re: Oil cooling your hub- NOT snake oil!

I mentioned to farfle that this could be taken to the next step since he is machining axles for the stator. You can build an oil circulation loop into the system by injecting at the axle and scavenging from out near the windings. The hub does not have to be filled for this to work if the scavenging...

Re: Sensor or Sensorless Controller...?

As far as 'getting off the line' is concerned, I would say dogman hit the nail on the head. These controllers always end up driving the motors 'forwards' unless there is some resistance (perhaps slight incline) in which case they 'cog' backwords, try to drive forwards and stall out. On the flat I do...

Andje, That's a chunk of power! How're going to cool the motor in the summer? Oh that's right, that thing on the right hand side of the handlebars ... is not an 'on/off' switch it's a throttle :shock: ...! Talking about Frying.. I blew a FET on my commuter bike yesterday. It's an eZee front hub with...

Re: BikeE - 9c 8x8 - 18s 2P -Lyen 18 Fet Project

Hey Silverheels, Sounds like a good plan. I agree w/ Icecube about these motors, I've had mine too hot to touch many times and it takes it. Over 2800 miles runnin 24s w/ the same Lyen's controller you are talkin about. So you should be able to run 24s without any modification. I set my LVC for 3.3v...

Re: BikeE - 9c 8x8 - 18s 2P -Lyen 18 Fet Project

Venting the hub does plenty, I've seen it on a thermometer. You may not be able to run a whole lot longer, but you'll cool back off again ten times faster vented. I ride though a lot of sand, so it's not an option for me to vent a dirt bike. Short hills, good. You should have no problems then. If y...

Re: BikeE - 9c 8x8 - 18s 2P -Lyen 18 Fet Project

There is supposed to be a spray for corrosion for the covers. Think its Corrosion X and also another spray enamel/varnish for the motor stator and windings itself. I would probably dab some RTV silicon on the hall wire legs. If you are in a sea boarding state/city or just have high humidity in gene...

I dont know what hills you have but my 9x7 scoots up anything I throw at it at 66v 45A. Its taken the hill on my street several times in a row... dumping 4000+w into it each time. These motors are alot more forgiving than you think. Good to hear that! I guess that as soon as I start playing with it...

Dogman: Thanks for the temp hint, it seems to be a key part of the experiment :] The two hills are short, but steep, at present my eZee (48v LiFePo4, with 22a controller) and mucho pedalling takes about 10 mins to struggle up the one, and 15 mins for the other. I'm hoping to test the heat soak then ...

LL: The Teflon is not the bendiest of wire, however it's not bad. This particular version of Teflon coated wire consists of counter-wound layers of thin Teflon and seems more flexible than some. I removed the top layer of Teflon, this seems to help with making a reasonably small drip loop, makes a h...
