RagingGrandpa Posted March 27, 2023 Share Posted March 27, 2023 Evidently, yes, we should expect to see higher frequency of fires in those EUC's from ~2020 that use LG M50T cells in 4P or smaller configurations. 1 1 1 Quote Link to comment Share on other sites More sharing options...

I think it's "old news" at this point... no EUC's produced in the last ~1.5yr have used that poor-reputation cell. And I think "Gotway fires" was a topic with lots of community hype during late 2021. Plenty of info to be had in all social media. 2 hours ago, Robse said: (my) RS 19 from Late 2021 Just lift up one of your battery packs and inspect the label. It's likely Samsung, or the newer M50LT.

For example, with our machines specifically I don't think I have seen a single report of a Master just sitting there doing nothing and then catching fire, except that one time where the guy thought he got water in the charge ports in a previous ride... now I know it certainly doesn't preclude the possibility of a fire with ANY machine, but I think if you have nice, safe 50e's, have treated them properly, and looked after the machine, the risk of those going up is an order or 2 of magnitude less than if you have an RS with those dodgy cells sitting in your living room. Or is that flawed thinking ? I am just aware how easy it would be to be paranoid when this forum has become a hub for fire reports recently ! The incidence of these, as I understand it, is still very low per units in circulation. I totally get the negative outcomes of more attention to fires...BUT I would just say its def on us all to keep fire reports relevant, factual across all forms/platforms riders consume any content or information. information saves lives. the packs with latent fire risks would typically manifest over time, usually beyond begodes warranty. they would likely not show any signs of deterioration or pack failure until the problem is beyond address. - It would be advisable for anyone with an RS to first identify the cells used in their packs. This is a free & easy way an euc rider can help assess their risk without technical or engineering experience & without concerns of "not wanting to work on my wheel" d/t removal and installing of a shell panel only. its essentially pulling behind the curtain. this can be done with just removing the right outer shell (control board side outer shell to see the label on the battery - the label on the left side battery should be on the underside of the battery, and is why the right side is usually a good place to start). RSs sold from RevRides 10/2021 onward should contain packs with either Samsung 50E/50G cells. RSs with 50E/50G cells from revrides have charging current limitations of ~3.1 - 3.3a per pack limiting fast charging to a maximum of ~6 - 6.5a. These packs are not known to be susceptible to the same relative or latent fire risk posed by the LG M50T based packs used in this wheel model. so, folks with older wheels like an RS, arent necessarily less safe than a current master. as of 03/2023 all Master, T4, mTen4, EX30 from REV Rides contain (and have contained) 50E packs However, i have personally serviced RSs; riders have not purchased via REV Rides & seen some wheels with begode 100v 900wh packs with serial numbers confirming build dates as recent as 12/2021. I know you can still buy RSs EX.Ns, EXs on aliexpress almost exclusively with the linked LG M50T cells, and is where i see this being a problem not yet resolved in terms of product STILL available on the market, not product that only lives in the community.

I'm kind of in the market for an S18 because it's so lightweight. I'd love to get one cheap with dangerous cells, and then swap the cells out. the S18 from first batch onward has been M50LT cells. the S18 then became available with molicel p42a. to my knowledge, those are the only cells used in the s18 historically. this is the same cell (M50LT) as they use in the s22 (except ewheels 40t). KS use try to use these in all packs that contain 21700 cells unless customer/wholesaler seeks specific alternate packs. just like they do their own control board design and manufacturing in house, they do the same with batteries now too. recently it seems king song is considering discontinuation of the p42a supposedly d/t costs. 4 hours ago, Paul A said: Is it likely that other Begode RS models will ignite, as they age? no - see this response Quote Link to comment Share on other sites More sharing options...

Asphalt Posted April 20, 2023 Author Share Posted April 20, 2023 April 19, 2023 RS HS fire https://t.me/mono_man/14334 Translation from Russian: #Almaty #fire RS HS . 15,000 km. mileage. Was under repair, installed 6 new cells. Caught fire while charging native 3A. The place of ignition is a private house under a canopy. No one was hurt, except for the nearby T4, which was burned from the outside. The fire was quickly extinguished. Be careful. He escaped with a slight fright. If it caught fire at work, in a car or in a cafe, somewhere on a charge, it would be sadly strong. Be vigilant and careful! 1 Quote Link to comment Share on other sites More sharing options...
