    BTW, Genze has issued their first recall. Should not be a surprise, I hope nobody has been seriously hurt by one of these.

    Mid-mount Hubmonster Madass

    This is an excellent set of goals and great initial analysis of your roadblocks. I would definitely shy away from using a hybrid mix of batteries, but you were probably aware of that and are asking out of a more scientific curiosity. Unfortunately i don't have any expertise to add on that other...

    Battery pack size for electric motorcycle moped?

    http://lunacycle.com/batteries/packs/ https://endless-sphere.com/forums/viewtopic.php?t=26383 There are a few available packs (for ebikes) that fall into the size category you are suggesting. The lipo packs are a bit more flexible in that you can get damn near any combination of series cells...

    Battery pack size for electric motorcycle moped?

    Hub motors of every size do exist...So that's always an option, frees up a lot of space in the middle of the bike and eliminates any need for a belt or chain, as well as adjusters. Both types have their pros/cons 25 miles at moderate speeds (30-40mph) can be done with a 2kWh pack quite easily...

    Battery pack size for electric motorcycle moped?

    Yes i am familiar with the Bolt, but it's not a production bike so you don't want/need to go copying their specs. They are catering to the opposite type of person than you, a builder. I also maintain that a 100+lb vehicle should not be running 48v. Especially if it's pushing 300A, that's just...

    Battery pack size for electric motorcycle moped?

    Multistar Lipo packs 48v sucks though, i would go for at least 72v. Make sure you look at the KV of the motor to ensure that you will reach the desired top speed. Additionally, if you go with a sine wave controller (Adaptto, Kelly KLS), which you should, you'll need to subtract 15-20% of...

    My solution to Li-po Fires

    Yeah i'm curious too. I'm building a pretty big pack and have all the equipment to do similar vacuum bagging/resin layup. I'd definitely go to the trouble if it kept the pouches happier. The formex stuff looks interesting too, i could cut them out on my CNC die-cutter and make little boxes in...

    New Kelly pseudo FOC controller series

    Yeah I understand your quest for info, i just meant to say that for a 26" wheel there's no reason the Kelly controller wouldn't be suitable. This is based on my experience with running a 27" wheel with significantly less power (10kW). I couldn't say whether it outputs the exact amount of amps...

    New Kelly pseudo FOC controller series

    Since the S & D are in uniquely shaped boxes, the packaging size would be the first difference. The D offers higher continuous amp capacity the 8080 series has higher voltage and amperage and much larger packaging size 8080I uses 3 hall sensors The IPS series works with sine/cosine sensors...

    New Kelly pseudo FOC controller series

    yeah i guess my worry was all for naught, Fany confirmed that 100v is fine. 24s here i come!! Triple digit voltage, the future!

    New Kelly pseudo FOC controller series

    does anyone know if the KLS96 series of controllers will support a 24s li-ion pack (100.8v full charge voltage). I intend on using regen and pushing a lot of power through it, so it would be good to have some confirmation that i'm not asking for trouble with this combination.

    Genze by Mahindra, eScooter

    It does make sense... You would need to ride it for yourself to experience it, but you can clearly see that the riders feet are not comfortable where they are positioned. The flat area in the middle is a bit cramped, and people like to leave their feet right on the edge so that they are ready...

    Genze by Mahindra, eScooter

    You're spot on about the flimsy/not reliable part. It also does not appear to be meant for the california girl, or any girl for that matter. Seat height is somewhat high and extraordinarily wide, meaning only tall people will be comfortable moving their feet in and out to reach the ground...

    Genze by Mahindra, eScooter

    they've been claiming to be going into production since 2012. There's really no risk in waiting without a preorder, there are not a lot of preorders to begin with, and it's just a gimmicky incentive. If you still want a bike after the first few people have complained about all the completely...

    The EE's didn't do the design, although i agree it is terrible. The marketing director created that monstrosity of a design. Most of the engineers have already left the project, if you have put in a pre-order, i suggest you get it back before there is nobody to call for a refund.
