Neighbor gave me this same bike that he found at a warehouse. I changed the batteries and it worked perfectly. Thanks to your video I had no problem. Thanks again
Thank you so much for your video. We bought this bike used off some friends for our son, and the battery would only last like 10 minutes on full charge. Hoping with a replacement to get lots of use out of it!
Thank you so very much for the very helpful video! I just got done swapping the battery on one of my 8yr old twins cycles so now they can ride into the sunset.
Thanks great vid very informative with the screws thanks!! Will I need to solder the connections for the new battery or do the slide on the the terminals? Ordering new one either way as I feel these current batteries don’t hold charge but was just wondering thanks. I saw you soldered and then covered with hot glue looks like? Thanks again!!
Thanks for the very helpful video!! The 9ah battery you recommend is out of stock. Could you recommend another that is compatible with the razor zr 350?
What if I keep having to replace the batteries every two months or so? New batteries start off great but them seem to be losing their life quite quickly. I bought new ones 2 months ago and now they're back to charging for a few minutes before the light on the charger goes red to green. Then you can drive it for a few minutes before it begins to die.
Owner's manual says about 250 charge/run cycles can be expected from batteries - is this what you're seeing? Run time about 30 mins, prolly less with a lot of up and down hills or heavy riders. Manual also says 140 pounds max for a rider.
I don’t know why but the metal I bought for soldering is melting but it’s not sticking the metal to the little plate. It’s just clumping into the wires. What am I doing wrong
try melting the metal directly onto the little plate, i had a similar issue. If that doesnt work melt a good amount of metal onto the solder tip and rub it against the little plate then promptly attach the wire to it

First time using a solder, the process went well, its kinda ugly looking but like you said it works and its safe

Hi there! Your video is so good it helps a lot, what is the battery that I should buy and where
Awesome video and description, thank you for the information.
No one shows how to get the seat and plastics off. I'm sure I'll figure it out but I didn't really see and screws or anthing
How fast dose it go
Anyone know if it's safe to cut the wires and take them off the battery if the battery has bumps?
How long run time does the upgrade give you?

How do the charger look like
My old mx350 is rotting away in our backyard. Literally beyond saving 😢😅
What is that battery name
Good job
dang i thought you were going to show us how to test batteries if they are still good
Hello Chris
Hello Jeanetta, thanks for watching:)
Maybe I missed it...did you show people how to check if the batteries are good or bad? I think you need a multimeter.
Put Alcohol or nail polish remover on hot glue on the terminal will release it
