Re: Commuter Booster - <1kg Friction Drive

Do the above ESCS work with hub motors? And for clarification, 7s M1 is 3.3 x7V not 3.7 x7V.. so 23.1V (not 25.9V). This trigger has about 18 degrees movement in forward and "reverse" directions. If connected to a hub motor it would allow you to brake. Might be able to re align to skew towards a max...

Re: Commuter Booster - <1kg Friction Drive

Thanks for the info. I may or may not have mentioned that I'm running 7s 26650s. Getting a hyperion 1420i. I don't need to have everything working by a set date.. I just wanted to avoid bringing a bunch of tools to school. Turns out I have access to a bunch of tools at school anyways (ev club), it's...

Re: Commuter Booster - <1kg Friction Drive

Can't I just run a little fan over the hv 120? I think it's a $100 dollar difference between the 120 and 160. I think I might go all out and get the 160, and have it for other future ev projects. As for the Hyperion ZS 4035, I can't find any hard testing of it for this application. It does have a sm...

Re: Commuter Booster - <1kg Friction Drive

A punch? What is the real advantage of going with the HV160 for $225 on ebay? I know it can accept a lot of input and take a lot of current. It's also a US manufacturer with high reputation I believe. Also, I'm trying to stay away from hobbyking right now. I still have one of their helicopters that ...

Re: Commuter Booster - <1kg Friction Drive

I meant for handling 100 amps of electricity. I would never make a spring. I noticed that the 63-74 motor has the casing screws. would it be possible to cut a piece of slick bike tire and wrap it around, securing it with washers and screws that are a little bit longer than the ones there? I think it...

Re: Commuter Booster - <1kg Friction Drive

DO you think that 8 gauge copper wire will be just right for this application?

Re: Commuter Booster - <1kg Friction Drive

I meant holes on the arms for mounting the motor. I believe 5/32" is right (error in post) but I don't have a motor on hand to try. Adrian: so you think the big 63-74 (the one you're working with) will be okay on a little 85A esc? Are we talking about using no motor under 15 kph? I'm also interested...

Re: Commuter Booster - <1kg Friction Drive

My initial impression was that Adrian had one lying around after deciding not to use two arms. I'm going to try to build one with the 1/8" aluminum I've got and some jb weld or something to keeep them together. It'll be around 12.7mm wide with four plates. Might consider 3. As far as the mount goes,...

Re: Commuter Booster - <1kg Friction Drive

I saw that post when I went through the thread. I just was seeing if maybe others might come to encourage me to use what I already have. So you think it might have to be metal? I guess it would need to ahve the least give possible.

Re: Commuter Booster - <1kg Friction Drive

I see where you're coming from and I'll consider using thicker aluminum. However, I just wanted to do it within 2 weeks because in 2 weeks I'm going back to school and don't have access to same tools. Ordering a sheet online might get here in time, but I have some time on my hands to make it work. I...

Re: Commuter Booster - <1kg Friction Drive

It's okay Adrian, but maybe you can provide some guidance on my build cause I'm just starting out.

I found a sheet of aluminum from ksmetals at my LHS. I paid $15.

it is .125x6x12". Could I fashion an arm with this (possibly through layering pieces up to 1/2")?

Re: Commuter Booster - <1kg Friction Drive

Adrian, do you mind cutting me a mount as well as an arm (paid, of course. I don't know what you paid for materials though, but would estimate around $50 for whole deal shipped?)? I'm under the impression that you are not planning on going commercial with this. Correct me if I'm wrong. I'm intereste...

Re: Hyperion EOS 1420i NET3 14s Balance Charger...

Let me rephrase: what charge rate could I see when I hook up my 1420i to my 430w psu that has a 32A net max on the 3 12v rails combined (16A individually but they are all hooked up at one)? this is for a 7s2p or 6s2p a123 26650 pack. Also, how I limit the current coming out of the psu to the hyperio...
