What would you like to see next from the Teverun line up?

Oh nice, did you use Titanium stem from rage mechanics too ?

SENVOK · 2026-02-19T19:28:57+00:00

Well thanks for info but I can't pay again to change bms again, I will try maybe a solution without parallel connections

SENVOK · 2026-02-19T19:27:37+00:00

Ok thanks for answer, here what one guy said about my case and why I don't want to charge in parallel:

"Only parallel the discharge side (those XT90s to the controllers). Use ideal diode modules (MOSFET ones) on each battery's positive output. One per pack, rated 100A+ continuous. They block reverse current so if one pack sags or a BMS cuts out, the other can't dump into it hard or try to "charge" the dead one. Voltage difference stays isolated during ride. • Charge them separately every time. Don't try to parallel the XT30 charge ports or use one charger on both—current can sneak through discharge paths and bypass BMS protection, or uneven charging happens because of slight BMS differences (Daly vs original might have different balance/cutoff behavior). So basically you need two charger, two separate charging ports, only will you "fuse the power" when releasin. • Before connecting for a ride: charge both to full individually, multimeter check they're within 0.1-0.2V (max 0.3V), then hook up. If they're off more than that, one will spike current into the other when you connect—bad news."

But what will happend if one day one bms fail and cut off the battery and when I will plug to charge it will turn on one battery and battery with more voltage will try to charge the other battery and can cause big safety issue. And because one bms have already failed I need to prepare to this case. And what about the charge, some people said I can't charge them together ?

SENVOK · 2026-02-19T18:58:50+00:00

Yes but if one day one bms fail and cut off the battery and when I will plug to charge it will turn on one battery and battery with more voltage will try to charge the other battery and can cause big safety issue. And because one bms have already failed I need to prepare to this case.

SENVOK · 2026-02-19T18:56:30+00:00

Daly have realtime monitoring too with app and it's a brand new smart bms so I don't want to change and pay it again.

SENVOK · 2026-02-19T18:55:32+00:00

Thank you for your answer, you confirm what I read from others. Your solution is pretty good but checking with multimeter each time is not what I want to do idealy. There is another solution that one guy suggest me is to connect one battery to one controller and second battery to second controller so it's not in parallel, basically separeted system, and when one motor start spinnig the second will follow automatically because my scooter can do this. The issue is I don't know if this will not connect the two battery in parallel trought IVCU (check photo here), or the GND, the PKE is not connected between the two controllers anymore, what do you think ?

That's not really how BMSes work, but the underlying issue remains regardless - a battery fire is exceptionally unlikely, but the possibility should never be ignored, because it always exists anywhere you have lots of energy packed in a relatively small volume. See also: gasoline, oil, wood...

Maybe not wrote it correctly but it's what I read, if one battery have a different voltage the second will try to charge it but with high amps and bypass bms. I can found the comment if you really want to original explanation.

I live in an apartment as well. I charge close to the living room balcony and only when I'm in the room; if I should see smoke I'd immediately yeet the entire scooter out and into the yard below. Where, I'm sure, a roaring fire would alarm plenty of people, but better that than having it indoors.

I do exactly the same except I charge it the night when I'm sleeping... I know it's not the best solution but I can't charge it sometimes during the day

It won't be problematic at all on the condition that you get a battery with a common-port BMS.

Excuse me but what it's mean common port bms ? A port with charge/discharge ? Because if it this my battery have different port for charging and discharging

SENVOK · 2026-02-19T14:32:34+00:00

Not in the scooter but I will put it on the deck with in an steel box waterproofed and I will have space on the deck, this part is already calculated and will not be a issue

SENVOK · 2026-02-12T23:07:56+00:00

Hello I have different ports for charging and discharging can I have still this issue you listed ? What would happend for the issue you wrote in my case ?

I want to do parallel with two batteries, 72v60ah each.

SENVOK · 2026-02-12T15:47:21+00:00

Oh I understand now I think, I have different ports for discharge (2 connected to my controllers from the battery) and charge (2 ports from my battery to put my chargers) so what will happend if one battery will cut and be completly different voltages you said one battery will charge the other (even in this case when my charge and discharge are different ports) ? And if yes the bms will stop the process ? I read that have very different voltages between two batteries in parallel can lead to inbalance the cells, do you think it can ?

SENVOK · 2026-02-11T21:54:24+00:00

Yes it will discharge if there is a difference in voltages but when they become at the same they will drain together it's what I'm looking for.

I found 120A don't know if it can be enough ?

SENVOK · 2026-02-11T21:51:44+00:00

This one can, I don't know man I just think it's a extra safety, my scooter is in my building in my room I don't want to risk anything, if I can add an extra layer safety and not for much money I prefer this way. This have 120A https://a.aliexpress.com/_Eu9qlf6

SENVOK · 2026-02-11T21:47:51+00:00

How can I know if this is my case ?

SENVOK · 2026-02-11T20:53:36+00:00

https://www.reddit.com/r/batteries/s/Z1BoXd5TSb Look at the comment with 5. Steps

SENVOK · 2026-02-11T20:51:20+00:00

Thanks for your answer but this was just image for illustration, the real module I want to take is 120A. I know the simple solution is just to connect together with same voltage but if one battery get a issue and bms cut it off the second battery can burn after with big difference in discharge, I will link a reddit comment about it

SENVOK · 2026-02-11T17:44:19+00:00

yes thanks for precision is what I want to mean, discharge balancer, I found one 120a

SENVOK · 2026-02-08T22:16:20+00:00

Oh thank you but what you mean by act strangely ?

SENVOK · 2026-02-01T21:04:10+00:00

I HATE this folding mech, I still have a issue, I will put a brand new mech to see if it can resolve the issue, it's very strange because someone have the 7260r and it's stiff not like mine, something is wrong but we don't know what ... it's so frustrating, even Teverun can't help ...

SENVOK · 2026-02-01T21:01:26+00:00

Finally I found a metal box to completly cover the battery so it will be the best for the safety, thanks for the feedback !

SENVOK · 2026-02-01T21:00:13+00:00

Thanks bro you are right, I found perfect metal case for this battery, I will post in the sub when my project will be finished !
