Hello
My sin (8y) have Hoverboard hummer 8,5” with kart
The problem is the battery !! He can drive just 30 min with the new battery 36v 4,4ah (changed last week)

I want to know if it’s possible to add external battery (parallel 36v but 8,8ah) ?
It’s possile to connect it on the battery wire inside and put in a bag outside behind the chair

Thank you

Hello @Danyparis Again xd,

Get this : https://www.amazon.com/ShareGoo-Connect ... 79&sr=8-21

And try to get the same battery voltage 36v ( VERY IMPORTANT !! ) & IF YOU CAN the same Amp on your battery . if old one was 4,4ah, get a battery with 4,4 ah as well :mrgreen: .. If you are not doing that, you gonna have big problem .. Like, it can burn cable because the charge is not going to be the same on both battery ...

dear lexfire thank you first of all for your contribution the problem I find is how to open the battery without damaging the box if you give us a demonstrative video and very detailed even with the reference of the controller and its link it will be nice of you , another question for the lights is what you managed to make them work with the display cordially, to extract the battery I found the solution, which is to after opening the location of the controller there is a plug black which comes from the battery holder take you the red file and the black one and you feed them with a current 5 volts and hoop the battery leaves waiting for your video if possible thank you

cher lexfire merci tout dabord pour votre contribution le probleme que je trouve c'est le comment ouvrire la batterie sans domager le boitier si vous nous faites une video demonstrative et bien détaillée meme avec la reference du controleur et son lien ca sera gentille de votre part, une autre question pour les lumieres est ce que vous avez réussi à les faire fonctionner avec l'afficheur cordialement , pour extrair la batterie j'ai trouvé la solution, qui est de apres avoir ouvert l'emplacement du controleur il y a une fiche noir qui vient du porte batterie vous prener le file rouge et le noir et vous les alimentez avec un courant 5 volts et hoop la batterie sorte en attente de votre video si possible je vous remercie

Hello mate
Yes the both battery are the same
36V ans 4,4 ah
The charge for the external Battery don’t pass with the Hoverboard but with a second Charger
Why i want to install a external Battery ?
Because the Hoverboard run just 10 or 15 min with the battery and sometime 45min
I don’t know why ?!
Now i have change the BMS in the battery inside
Maybe the problem is there
