Ok guys, a lot of you here seem a little lost on what to do with your defective XR batteries and the problem at hand. Most likely you guys are suffering from an issue called 'RLOD' or "red light of death". This issue stems mostly from an internal cell imbalance, as explained in the video. Boosted XR battery packs are made from an array of 26 individual cells. What happens over time is these cells can become imbalanced; essentially the voltage of the individual cells differ beyond an acceptable range. Boosted was aware of this issue and is was one of the reasons they completely redesigned the XR battery.. Cell imbalances we're causing the batteries to start smoking and exploding! Luckily that's no longer an issue with the newer packs since all of the old ones were recalled. Keep in mind, this is an issue that lots of battery packs made up of lithium-ion cells face. So boosted redesigned their BMS (battery management system) and programmed it with a safety protocol for if the cells became too imbalanced. This IS a permanent error and the only way to remedy this would be to reset the chip responsible for the error, which wouldn't fix the actual problem (it would simply prolong battery failure). Or you'd have to replace all of the cells in the pack/the individual cell with the lowest voltage. RLOD can also be triggered by extreme overheating or all of the cells falling below an optimal charge level, from leaving the battery uncharged for a long period of time. If you guys are hoping to get your batteries fixed you have a few options: The E-board stuff website offers repairs, as does the boosted guys website. Boosted guys are also selling refurbished XR batteries for $320 USD. Additionally, There is a man based in canada known on the boosted board Reddit page as Venutech. He specializes in fixing XR batteries and is currently researching/working on them to improve performance! Contact him because he is a boosted expert. If you guys are wondering what you can do to prevent RLOD from happening, just know that it's not a problem you can avoid forever but you can greatly extend the life of your board by taking some precautions: First download an app called 'boosting' to check battery firmware. If you have the firmware 2.5.1 or higher you're one of the lucky ones. The BMS has a way of telling you that the cells are imbalanced by locking the battery percentage (while charging), until the BMS has safely discharged the other cells to match the voltage of the lowest one.This can take anywhere between a few hours, a few days, and possibly up to a week. Just know, It's important to leave the board plugged in for as long as possible until the light turns green indicating a full battery. Also Keep in mind this isn't a regular thing; your battery actively balances the cells everytime you charge the board with this firmware. Once the board goes through this long process, you have an even longer period of time before the battery has to do this again. If you have firmware lower than 2.5.1 you have to leave your board plugged in to 2 weeks. This is a long period of time to wait, but it's the only way to balance the cells with that firmware. After which you should be safe for several dozen charge cycles until it has to be done again. Regardless of what firmware you have- always try to charge the board to 100% every time and don't let the battery drain to 0% after every ride. If you have the time, leave the board plugged in for an extra half hour to a full hour. If you guys have any further questions on this topic feel free to ask!
Thanks for your explanation. The only problem is that I am based in France and it will be too much expensive for me to send my battery (who has already that RLOD issue) to US or Canada. I am looking to fix it by myself or eventually by someone based in France. If only the guys who are fixing those issues could make videos or tutorials that we could follow, even if it shows materials we should use to get it done. 🤞🏻
I'm very sad to say that the RLOD just happened to me this week. I'm keen to opening it up and try to sort the issue based on vids I saw on UA-cam - but the option of leaving the board connected to the charged for a week or two sounds a safer approach. Is it guarantee that leaving the board connected to the charged for that period of time will re-balance the cells and will work fine again? The day I got the issue I rode my boosted mini x to the limit until completely stops on the road. I did now know this was not a good idea. Anyways. Your feedback is greatly appreciated. Cheers,
Any way you could look into a solution? Boosted went out of business and a lot of people have this issue. Or point us in the right direction. We'd all appreciate it.
My boosted board's battery has got the same error code... I am really hopping to see an open source / direct replacement BMS... Actually this makes me thinking that there should be a way to inject a reset signal there or maybe somewhere else on the PCBs. At this point is it a hardware failure or firmware failure? ... Guys I will probably disassemble mine one of these days but if you have any idea or advanced research on this topic I would be happy to collaborate. I do have electronic skills (EE).
@@carlossalazar972 Thanks actually what you are explaining in your next message is absolutely correct. I posted this message before finding how to clear this safety flag in the flash memory and publicitly releasing the method on github. It is great to see it used by Venutech and other people :-) Best,
I Charged my board after my winter storage, the indicator showed me full charge from start but i kept it in for 1 hour anyway. Went for a ride, after 1/3 of the max range the board started to work funky, stopped a second the went on again a few seconds before it stopped again with the RLOD on the battery. I've had it in the charger for 1½ months without any luck. Dissembled it to measure the cells. All cells were around 0.7-0.9v. So im guessing the battery is 100% dead My conclusion is that the BMS only counts amp in and amp out in seconds to give us the charge status. And it doesn't care at all about the cut off voltage for the cells. That's why we got so many RLOD's, the charged % counter is off and the board allows discharge over the cells minimum which can damage the cells permanently. I guess the only way to stay safe is to "overcharge" it often, leave it in twice the charge time just to sync the indicator.
Same exact error code. 3 Blinks over and over on power led, 4th light up constant. Also pulled mine apart but no burnt out components that I can see so far

I found out how to reset RLOD. Short pin 1 and 2 on ISSI IS25LP128 chip. I've made a short video on it.

Are you referring to three blinking lights with the second dot illuminated?
I cannot find the app boosting, link me it please?

pleaseee help we’re a community of people who got screwed by boosted with that blinking red button problem, what should we try to fix our batteries
OMG SAME. Can we please get any help Battery Doctor
I have the same problem
Hi Leo, if you are / have geeks around you try my method: github.com/jonataubert/RLOD_B2XR
Aldrich Mascarenhas contact eboardstuff he got a fix
If you aren't already join the boosted board Reddit community and message a man named Venutech. He's based in Canada and specializes in XR repairs
Any way you could look into a solution? Boosted went out of business and a lot of people have this issue.

I have the same problem
Take a look at the comment I just posted, hopefully that sheds some light.
Hey,
I have the same problem and now after Boosted went out of business, I looking for a solution by myself, any good tips where can I start?
Most likely boosted did not invent new motors and there are many DIY ebike kits ehere you kind ESC thath might work with boosted motors.
That looks like the RLOD ( Red Light of Death) check on the boosted reddit forum... 👍🏿
I have the same problem
Take a look at the comment I just posted, hopefully it helps!
Any idea how to remove cells from the pack? I’m trying to replace them. I have a v1.

There is a RLOD fix on Github
If anyone has a boosted board battery case can you please sell it to me bc i broke my case

What is the battery for ???
Is it a bird,or a plane or a skateboard ????
Again,thanks for sharing.
its for a boosted board, a electric skateboard (this model battery is for 14 miles but boosted has a 7 mile battery version)
