Gotrax Electric Scooter Battery Repair Cell Replacement

In this video I'll show how you can fix your Gotrax battery I done it on Glider but I think the process is similar to all Gotrax in handle batteries.
You can see how to remove old battery disassemble it find broken element
assembly the battery and scooter

[@taigaw67]

Thank you for this video. I am looking to disassemble and repair the same type of battery from my GoTrax GXL V2. Your video certainly has confirmed for me the process of replacing dead cells. Much appreciated!

[@RomaFixcom]

No Problem ...

[@user-bw9bh2xb8v]

did you do any replacement to the old pack ? what is the result ?

[@dennispangilinan5153]

I have a question for you. How can you remove the speed limiter on gotrax g2 plus? would you be able to guide and do step by step instruction? that would be great if you can. thanks

[@LeoLopesLL]

If you still have this scooter (or a charger): would you be so kind as to let me know what the connector is? I thought it was a failry standard 5.5 OD by 2.1 ID, but it doesn't seem to fit. My caliper says OD 4.5 but there is always some measurement error there. I cannot find a connector that will work :( My scooter has the same overall shape but the battery is only 24V, the motor on the wheel says 250W.

[@tedhuntington7692]

would be nice to see more of the re-assembly- that part was totally passed over

[@PhoenixPLPhoenix]

That's axactly what I needed, I have a Soflow so1, it uses exactly the same battery, but it's 5,2AH. Thanks again now I know where to start. Stay healthy! Greetings from Germany

[@RomaFixcom]

Check that discharge rate to be enough ... I had another one and used weaker batteries and it was shaking on start.

[@carlosjimz]

I disassemble same pack to find 2 cells under voltage . Wondering what c rating batteries those are. Marked only with numbers starting with 0117030xxxxxxxxx 3.65 v. I'm testing for capacity now but I'm looking for max discharge C rating

[@forest3064]

You didn't show the process of cell replacement, is there a video on this?

[@jkucukov]

I have a battery just like that that stopped taking charge and upon disassembly have discovered corrosion on the spot welded terminals in the center section of the battery pack. It eh corrosion from the leaky electrolyte?

[@garcia9352]

pero q tipo de baterias tengo q buscar para q de 36V y 5,2 mah q voltaje lleba cada una y cuantos mah ???

[@ryguy694]

Hey thanks for the video! I'm looking to upgrade my friend's scooter to use higher quality cells than gotrax did. Do you know what the capacity and discharge rate of the stock cells were? I'm thinking of LG HG2 with the 30C rating, but wondering if it's overkill? Also, from your video I counted 24 cells total?

[@RomaFixcom]

I installed 2x5c parallel and when I was driving I feel that not enough but 30C I think would be to much. You need it only on start after consumption decreases.

[@ryguy694]

@@RomaFixcom thanks for the reply! Maybe some extra capacity with 20C might be better? Were there 24 cells total?

[@victorrodriguez4081]

@@ryguy694 did you end up replacing with a better battery?

[@ryguy694]

@@victorrodriguez4081 I replaced all cells with 20C and 2800mAh ones and it's working way better! Only problem is that I didn't weld one of the pairs well, so I have to take it apart again.

[@Igryan8]

Hey, man. Are you based in the US by any chance?

[@TinNguyen-bx5nk]

Hi do you think I can use a 36v battery for this scooter since my old one said 25.2v. Do you think it will burn my controller if I use the 36v for the replacement battery?

[@RomaFixcom]

I think controller wouldn't resist.

[@tht1guyfromtht1place70]

Hey i’m really glad you made this video I was wondering how these batteries were configured. Is this the 24 V or 36 V

[@cliffli798]

can you in theory replace all the cell and increase the range?

[@AB-bu8ti]

Thank you for this video. What tool did you use to charge the individual cells?

[@RomaFixcom]

They where already welded in pairs so I simply soldered them but it you have separate cells you'll need spot welder.

[@AB-bu8ti]

@@RomaFixcom thank you for the reply. Did you charge the batteries individually before reassembling? Maybe I misunderstood you in the video.

[@RomaFixcom]

@@AB-bu8ti I tested each pair and found out that I had only 2 pairs defective, I keep original non defective cells and added 4 more cells (2 pairs).

[@larryhullinger4141]

My gxlv2 needs a battery but none are available I can get one for the gxlultra Both are 36v batteries but the ultra battery is 7ah The v2 battery is 5.2ah Can i use the ultra battery in my gxlv2?

[@RadBudaspectrum-photography]

Hi buddy. what voltage do you get from the battery connector? all cells connected getting 37V from battery terminals. connect the charging board (board at the top of the battery unit) I only get 14V + and -????

[@RomaFixcom]

Maybe you have 36v battery, but it seems to be BMS problem.

[@RadBudaspectrum-photography]

@@RomaFixcom it's gotta be, I think is a chip on bms. Once power removed chip dies, I had similar problem with my dji mavic drone battery. It's OK to have lower voltage as long as there is one to keep the chip alive. Got new battery today and power is 39V from factory connection.

[@user-bw9bh2xb8v]

what is the reason to lead you opening the battery pack? Low voltage or quick drain of battery?

[@RomaFixcom]

not charging.

[@ronb-ks1ot]

I haven’t rode or charged my GT tracks V2 in over a year. I take it out of the shed charged it up and it’s not moving. Does it need a new battery even if the battery lifespan was fine?

[@carln7519]

does the charger shows that it is charging or doesn't detect the battery at all?

[@bluepearl411]

what type of batteries did you replace them with rechargeables if so what type

[@carln7519]

the size would be 18650 cells

[@bikeLife580]

I’m wondering if I can upgraded the battery of a Gotrax v2 but no vids about it

[@RomaFixcom]

I already changed my scooter but by the plan I was thinking to attach external 24V battery and use xt60 connector close to charging port.

[@tdcrom]

What model Gotrax do you have and do you enjoy it?

[@RomaFixcom]

Glider I prefer something more powerful but this one was really light to carry around.

[@mcgavin098]

10 batteries in series will give you 36V power. It's so simple to keep the orientation of the batteries right. It looks difficult to copy the processes from the factory. Battery length is critical.

[@RomaFixcom]

this is 6s2p as I remember

[@dreamteamgaming6642]

Can I mail u mine and u Fix it? U seem to have all the tools to repair

[@gugolbaho]

how can I locate the speed regulator of Gotrax glx v2 rival or any Gotrax model ?

[@RomaFixcom]

speed regulator you mean ESC ?

[@RadBudaspectrum-photography]

Do you think it would be ok to replace the cells with 3000Mah, 20 A discharge?

[@RomaFixcom]

Maybe 3000mAh 20A discharge would work

[@RadBudaspectrum-photography]

@@RomaFixcom I don't see why not. It's just a longer charging time. 20 amps it's plenty, i think.

[@victorrodriguez4081]

@@RadBudaspectrum-photography did you change it?

[@natalieushakova7727]

what was the replacement cell battery called?

[@RomaFixcom]

li-ion 18650

[@brianbmwxg]

Hi where do you get order battery?

[@RomaFixcom]

I got mine from electric tool, but you can buy it on ebay or aliexpress but it should have high discharge rate.

[@brianbmwxg]

I found those batter 18650 on high discharge 9900 mah 3.7v is that ok to use for gotrax when rebuild those? My only 20 cells on 5 spots each is 4 cells 2 Parallel. INR 18650-26E. I think it only 3.65v 2600mAh each. Now I bought 18650 3.7v. 9900mAh. Thanks

[@RomaFixcom]

@@brianbmwxg Discharge rate and battery capacity different things lot of chines sellers fake real battery capacity. between 2000-3000mAh this is normal battery capacity. 9900mAh are unreal nr for 18650 (and discharge rate usually is represented by "C" 2C 5C ...)

[@robd3123]

What do I do about a 30e code ?

[@RomaFixcom]

depends on controller.

[@nordicpride9708]

What is the part number for the battery cells?

[@RomaFixcom]

18650

[@wjatube]

Replacement battery costs more than the scooter.

[@RomaFixcom]

That's why to replace element's it's really cheap.

[@Xuryf]

oh... THX !

[@RomaFixcom]

You're welcome!

[@arimarie6611]

What’s the name or model of the scooter

[@RomaFixcom]

Gotrax Glider

[@John-ef9np]

Your better off jut buying a new scooter

[@SootyHunt]

This video is a waste of time unless you want to know how to disconnect it…. You see no work being undertaken, and you do not see him reassemble the battery with new cells… 20 mins of my life wasted !!! Pointless video tbf 😂
