Make any progress with this project? I've got a Zapino as well and converted it from lead acid to a cheap chinese lithium pouch cell pack. I went with 72v 50ah and cut about 93 pounds off the machine. Just put it back together as the weather is improving and I stalled out on upgrades that...

Thanks Marc, we've got similar fleets. I've got two Greenspeed GTOs, one with a BBS02 and the other one I just put a Luna MACv5/ASI hub combo on. Also have a Rans Tailwind and a Rans Wave, with a front hub motor on the Wave. And a few others including a Gary Fisher MB I put the BBS02 on and...

I bought a Satiator for charging a couple of Luna 52v 20Ah packs, a no name Chinese 72v 50Ah pouch brick and a couple of 36v 10ah packs in series for 72v. Really liking the charger with my only concern being how hot it gets. How hot is acceptable? I really like getting to measure how much...

Used to be that I might see one of two e-bikes a year in Tacoma WA area... within a 100 miles or so when I was riding a LOT. This year they are everywhere. It seems like maybe 30% of the bikes I see on the streets are sporting a Dolphin style battery pack. I'm up to 4 bikes converted to...

Today I finally did a ride that got me down to 2 bars on a BBS02 750 watt display. I'm running a Lunacycle 52v 20ah Panasonic (ncrb I think) battery pack in order to get a lot of mileage and longevity. I went with the older cell setup since with that amp/hr rating I'm not pushing the pack at...

I installed a Lunacycle sourced BBS02 on a 1999 Gary Fisher MB and the only issue with installation was clearance with the bottom bracket as well. I worked the center area with a dremel until it slid through, haven't had any related issues since. Wish I'd thought of using a reamer, I'm...

Been banging this idea around a bit and I'm at a loss. I have a BBS02 kit mounted on my mountain bike with a ton of lights that take usb style chargers. I have a couple of Anker 60watt 6 port chargers that will do 2.5 amps per port and they are tiny and they are relatively light. About the...

Wondering if there is a reason there aren't no spark connectors for the XT-60 connectors... I don't like that spark at the connector or at my outlet when I plug my charger in.

On these lines... I just picked up a new to me 1999 Gary Fisher Tassajarra that had been sitting in a storeroom for about a decade. Got the dried out grease in the shifters working and now ready to order up a BBS02 from Lunacycle... what has been stopping me is choosing a chain ring. Stock on...

Anyone actually read the paper this article with an unlabeled chart is based on? Sounds like one in an endless string of "We think on paper something is possible... we don't know if we can build it, if it is scale-able, what the life expectancy would be... but hey, let's announce that it is...

Is that a site like Alibaba, just all in Chinese? I can't tell what they are offering, much less who from.

The Orbtronics 3400mah batteries ARE the Panasonic 18650B cells... They also have a hybrid cell for high current applications that is good for about 10 amps draw per cell, but a lot less capacity at 2250mah, the CGR18650CH Hybrid IMR. The 18650 format doesn't make sense for most people doing...

Amazing what a couple of years can do... when I got into the lipo game with 18650 cells for my flashlights the Trustfire (don't laugh) flame 2400 were the best bang (hope not) for the buck cell out there. The Tesla Roadster was being built with 2200mah Panasonics. The Tesla S is being built...

The other major consideration that Tesla had to deal with was safety... they've got every single cell fused on both sides, got each sheet of cells fuses and the entire pack fused... all on top of the active water cooling system. I see no mention of the safety issues involved with a bad cell in...

I don't see how it is a scam though... you and I have never been able to buy their stock or invest in them. Some large venture capitalists have, it may have caused Zenn to self destruct in it's hopes this would pan out faster, and a major military company also dropped some coin. The company...
