You a genius my friend I had two of them scooters 450 models threw them away cause batteries were no good, only if I knew I can put my Kobalt 24V batteries but there long gone now this video will help others that have same scooters and have Kobalt 24v laying around garage 👍🏻
I have an e100 that I've been running off of 2 Milwaukee m18 5ah batteries I series for 40VOLTS LOL I honestly anticipated the speed controller to burn out within 5 min but it's been like 4 months and no issues thus far. I've also ran it with 4 2ah m18s and 2 3ah ho batteries. Went from like 6 mph to about 13 on flat ground.
I saw a video a year, or two ago, from a Russian who changed out the SLA batteries from his UPS for 18650s. Worked far better and something I always wanted to do just not sure how to charge them up since the internal charger of a UPS is made with a charging curve for SLA batteries not Lithium.
You can use a different/more lead compatible chemistry. I'd suggest LiFePO4, with a BMS for 12v, as the charge and discharge states are identical to lead acid (Pb) cells. in 4s you get 14.4v~ which as far as Lead Acid UPS is concerned is the same. You do need a BMS to keep the cells in balance or a active cell balancer, otherwise you'll end up killing one of the 4 cells in series. That's the only minor modification I'd suggest other than using LiFePO4 chemistry cells.
@@fang64 What I was thinking but the UPS will never know the real charge. Like the phone mod he did. The other thing is you need to tap the voltage point the UPS currently uses to supply its BMS for lead acid. Solder the new connections there to the new BMS.
@@generalawareness101 It'll be pretty close, Pb and LiFePO4 you can reliably use voltage discharge to determine state of charge, plus I doubt the UPS would ever allow it to pull a Pb(lead acid) too low anyway.
My thought is, why not mount the adapter plate at the base of the neck. Allowing for easer battery change. This would also allow for a small storage compartment under the deck.
On a 36v 350w controller and motor how far can I push the controller. Will it take 42v or will it just go wide open. So no point just get a new 48v or more controller. Plus the 350 moter I see u push yours hard so it can take more then it’s saying. I got 19-21 mph on my 36v 350w but looking to get to 30mph plus. It’s got 8” wheels so I been told put 10” on it will give 4mph more but help with the controller will it take 6v more or no
Can you help me please. I have a brand new Jetson ion scooter that i got out of box and is not charging. It was stored for couple years so probably the battery is completely dead. It has 42v 4.0 Ah battery and charge plug is the 5.5mm x2.5 size. Is there any way I can get this charging without taking apart? Maybe use different charger? It doesn't seem to be designed for battery replacement. Thank you in advance for any guidance.

Your videos are always a good watch even though I've done this 100 times myself
your crazy projects inspire me, good work man
Never cut positive and negative leads together, If there is any power in the batteries, it fries your controller board.

Never cut both battery leads at the same time. If there any charge it will short. Better to cut one at a time.
Positive first right
Good job and innovative effort. You made my day
please show how to wire the single battery. You show cutting only the controller wires but there are others
ANOTHER WORTHWHILE VIDEO--THANKS, KEEP EM COMIN!!
Why he didn’t attach the two kobalts in parallel is the biggest question 😆 that’s easy to do by making adapters then running the wires parallel
My thoughts exactly
Smoke..... Big smoke lol
I have a C35 SLA can I do that to it?
Would I have to buy a new controller
And charger if I bought a battery pack
🤔What's the voltage max for the Caps and fetts on the the controller ..... How bout you add another 24v and Buz light year it😁
What are your thoughts on a VISET LI 24V 1000mah, E-bike battery, 15A BMS for 100W-500W. Amazon has them for $149… could it work for a Razor E300?

Jr Eco one foot taller than the last time i saw him in his tester roll.👍
He's about to surpass me in a year! He's already eating more than me. :D
Do you live in Oceanside? Lol
And will this work with other brand scooters?

Have you run into over discharging issue? Would you recommend adding a BMS?
Most drill batteries have a bms built in to charge and discharge the cells
@@Mrbombardermaniac not Kobalt batteries
A lot slower than I thought it would be but it is more of a kids toy.

Can you over volt to 36v?
Question, Did you keep the stock motor?
👍
4ah? id use a few of them
LOL walking scooter home.
will this work for a mobility scooter?
Yes, it will. I made a video about it a while back. Here's the link to the vid: ruclips.net/video/5hv2Sr8CmdQ/видео.html
Nice
I guess if you want easy you could just use tool batteries.. but there's nothing like lithium and lipo stacking series🕳️👅🕳️
Note:= skyforce
Why he didn't! Is a Grammatical Error. It's proper use is: Why Didn't He! Nah Mean?
Noooo, you cut the battery + and - at the same time!!!! Cut one at a time so no battery short!
You're right. But you didn't watch the part where I said the batteries were dead.
@@vuaeco I watched but I must have missed the comment about the dead batteries.
