Re: DIY Battery Upgrades for Goped ESRs

6S Lipo packs actually works pretty well in the ESR. Comparable performance with the SLA powered version and the stock charger does a good job using something like a Chargery DB8 to keep the cells balanced and managing pack charging. I run a 6s4p (20Ah total) setup in my daughter's ESR. Since her ma...

Re: Ebikes.ca Cycle Lumenator is Here

Hi, I was warned that it's best they not be left on in still air. That sounds lame. If you want high output and small footprint, heat is going to be somewhat of an issue. I use a Cree LED tactical style flashlight mounted to my firefighter helmet. Its only rated at 190 lumens but the machined alumi...

Re: Are set screws dangerous?

Been using set screws for years. Use em on the drive sprockets of my 40+ mph stand-up gas scooter without ever having any issues after thousands of miles with the constant vibration of a 2-stroke. I do favor self-locking set screws over using thread locking compound and I always use a new one if I r...

Re: I need a little Hydrazine. Anyone got some?

My only point in my original comment was because I stumbled on the DEET for LSD synthesis while researching Hydrazine. I suppose it really isn't significant to most folks but I have some basic knowledge of the traditional chemistry and that one was new to me. I guess I shouldn't be surprised at such...

The T2 is designed off of what most of us are familair with as the Magmotor S28-400. The T2 was designed from the ground up but based on similarities as the Magmotor. Different winding, large machined aluminum heat sink on the brush end, and a slightly different diameter can. The T2 is intended as a...

Maybe its been covered but is it new within the last few weeks that we must scroll to view many of the images posted? Is there a way to make the window a little larger at least so reasonably sized images can be viewed without having to scroll, say maybe 800x600?
