August 13, 20241 yr Certainly shows promise.. even tho it has an app its NOT App Dependent (so far) the $1 buy in to get the deal is as fishy as a fish.
August 13, 20241 yr Fireproof? I don't believe it, but it is interesting concept. Worth to keep an eye on.
August 13, 20241 yr Certainly shows promise.. even tho it has an app its NOT App Dependent (so far) the $1 buy in to get the deal is as fishy as a fish. Where did you see that? Their Kickstarter deal is $330 for a complete battery kit.
August 13, 20241 yr Where did you see that? Their Kickstarter deal is $330 for a complete battery kit. The above link https://get.gouach.com/ takes you to an ad page for the promo but the 'reserve an invite' links which suggest access to the kickstarter offer takes you to a $1 via CC to secure your offer place page which raised my eyebrows..

That looks pretty fair. Pay $1 to reserve a 25% discount when the battery is available. Normally on Kickstarter, you'd have to pledge the $330. If they had a UK warehouse abd a 48v version, I would pay the $1, but $330 plus shipping plus VAT and handling charges is a bit too expensive for an 11.6Ah 36v battery. It'll be not so bad if it's compatible with Bosch mk 1, Yamaha, etc. The connector shows extra wires, presumably for comms.
August 13, 20241 yr I didn't pay the dollar for access to the kickstarter or a reserved offer place if/when it opens? but the ad page suggests both 36 and 48v versions will be (are?) available.. The $330 price tag would relate to the 36v and 48 would be higher but my reading of the ad suggests the offer is not limited to the 36v option.. Perhaps because i poured over the ad details so long the $1 surprise irked me so? And if demand for the offer was so high? wouldn't the dollar tickets have sold out instantly? So i fail to see the benefit of supplying payment details to a 4th party.. I will save my dollar and take my chances when reviewing the real kickstarter offer if/when it transpires.. (not that i have even looked at kickstarter itself..) Tho i have to say this dollar malarky makes me view the whole venture with a more sceptical gaze. A much simpler and less suspicious move would have been to just collect email addys for announcing and counting down to the kickstarter launch imho, both easier and cheaper to implement too.. (as well as providing a more generous/positive metric for pre interest if required, as its less likely to scare old grumpy sceptics like me off.. )
August 14, 20241 yr The product is (as far as I can see) a housing similar but tidier to the 'Vruzend' kit in that it relies on pressure to make the connection to the individual cells. I would not be sure how well or reliable it works. It probably needs to be fireproof! (imo) Edited August 14, 20241 yr by Sturmey
September 11, 20241 yr I've had a few emails back and forth with the owners. They run these batteries is a similar, albeit less smart form in two hire fleets. He also tells me they've reverse engineered bosch, brose and other protocols. Now that I'm very skeptical of. Even if they did, surely the next update from bosch or brose will stop it working. And that's an arms race they cannot win id have thought. Plus the myriad of different versions on bikes in the wild. Still these days I have an older bosch bike (moustache dual suss ) and my bbs02 conversion (to go south downs riding with my eldest now he is 14). If bosch doesn't work the bafang surely will. So I've paid my quid and will see what happens. I prob will just buy the casing and use different cells . Will report back as and when anything happens

I would not be sure how well or reliable it works. It probably needs to be fireproof! (imo) I read somwhere little balls of tin act as springs. That cell holder must be a very inflexible being able to hold the cells so tightly, with holder halves clamped together with so few bolts near the middle, I'm curious to discover how user dudes get on.

Could they avoid nullifying firmware updates? A baseless Bosch shaped sueball must surely be on it's way, to gum up the works. So I've paid my quid and will see what happens.

September 12, 20241 yr Hiya, Here the exact wording of their email to me "Hello Spanos, thanks for your message and for giving us a chance. It will definitely work with bafang. For Bosch we've managed to reverse engineer the protocols but they have so many updates that i cannot promise for all versions. Cheers" So make of it what you will! And I'd prob go molicel 35 or lg mj1. Both 3500 mah and 10a. Ive used the mj1 for years. Prob just get the cheapest at thr time !
October 1, 20241 yr So how do you guys read this ? Is it really saying only one hour to use our discount? I don't believe it's clear I got this today btw "
October 2, 20241 yr Sounds like you will have an extra hour to buy battery. Please let us know how battery is performing. Hmm... I don't see on/off switch Edited October 2, 20241 yr by Az.
October 2, 20241 yr I'll surely update...if I can If I only get one hour to use my discount I won't buy. I simply cannot be online then (I'll be in an aeroplane above Europe somewhere!) However, the sniff test isnt being past for me. It's starting to feel like an scam. Folk are minded to go with and belive in something when invested. Even a dollar is mentally enough. Let's see, hope im wrong

October 3, 20241 yr The on/off is done with an acceleration sensor (like Aptera's knock-for-entry) to keep the case watertight. The cells are gripped at 90 degrees to the main vibrations on a bike, and the 48V is presumably the same price as 36V but 39 cells instead of 40. Most of their site makes good sense to me, I'm in. Mind you at just 500Wh I might have to offer mine to you [mention=4312]spanos[/mention]
October 8, 20241 yr The on/off is done with an acceleration sensor (like Aptera's knock-for-entry) to keep the case watertight. Will the battery switch itself on when carried by public transport, or up stairs, lifts, escalators?
October 8, 20241 yr Will the battery switch itself on when carried by public transport, or up stairs, lifts, escalators? Yes, you only have to look at it hard. When you knock firmly on an Aptera they can roar off into the distance.
October 8, 20241 yr Yes, you only have to look at it hard. When you knock firmly on an Aptera they can roar off into the distance. I wasn't envisioning ebikes bashing themselves against train doors in transit, or ebikes escaping up escalators lol... but if it's an accelerometer activating the battery's BMS multiple times a day, won't electrons wear out some switching component on the BMS sooner than usual?

I don't think it's impossible that this company has reverse engineered enough of Bosch's protocols to do the job. One of my customers sells and installs Ghost immobiliers - the hackers who created that system haven't completely reverse engineered Range Rover, BMW, Mercedes etc. protocols, but they have utilities which identify which codes activate which subsystem they need basic control of, using the CANbus system to create the immobiliser. If they encounter a completely new unknown car, apparently they bring in a crack Russian hacker who plugs his laptop into the car, runs a bunch of routines while watching the screen output looking like The Matrix, as the utilities help identify the required codes to try. My customer couldn't provide any more detail unfortunately. I'll waterboard him next time. https://www.autowatch.co.uk/veh-sec/ghost-2-menu Edited October 8, 20241 yr by guerney
October 8, 20241 yr It's starting to feel like an scam. It doesn't look like a scam to me. Just one of many startups out there. For me lack of on/off switch is a deal braker, but for sure battery as a whole is an interesting concept. I will consider it when I will need a new battery. I hope they will make some improvements by that time.
October 8, 20241 yr To be picky for a moment my understanding is that it does have an on/off switch, I'd assume with on being activated by a gentle sharp tap and off by disconnection from the cradle or a timeout while disconnected, or something along those lines. They mentioned an accelerometer, the output would be filtered (or better) to only accept a sharp tap, not the softer sways and bumps of being carried around. Can't find it now but their BMS includes something similar to a pre-charge circuit that mainly protects the battery contacts and would also give the controller capacitors an easy life, and the MOSFETS themselves shouldn't wear through switching often. Assuming the battery stays on while riding when is it useful to be certain it stays off? When the bike's parked curious fingers can turn any battery back on; when handling it things can bump a physical switch back on; I think it's mainly useful for shelf storage and they've got that covered.
