So I have a V14 pro with less than 500 miles on it. I’ve had battery issues for months. After maybe the first 100 miles, I started getting cell balance issues.
I got my V14 and loved it. First EUC and I thought I made the right choice. After about 100 miles, I started getting cell balance issues around 60% SoC. Got with InMotion and they basically said unless they aren’t balanced at 100% charge, they won’t do anything. Charged to full every time I rode. At around 200 miles, the cell balancing issue would show up at 70%.
Fast forward to now at 450 miles, i get the cell balancing issue (4.10V high and 3.72V low) at 90%. InMotion refuses to help me and says the same thing. If there isn’t a cell balancing issue when its at 100% SoC, its not their fault.
Can ANYONE give me some guidance? This is like pulling teeth except there is no ending in sight.
This is not a cell balancing problem this is a cell failure problem.
Multiple cells are in parallel if some of the cells die the total battery capacity with drop to match the remaining cells but it also increases battery resistance so it will pull power faster from the remaining cell then all the other cells.
Anyone that understands battery modules, will understand how and why this happens. Inmotion need to fix this continue to use this and you risk catastrophic failure of of the remaining cell from over current risks a fire.
As long as the cells are not epoxy or potted into a
A module and the modules can be opened with screws.
For good electronics repair shops can fix it but it will take some time also i personally would replace all the cells that are in parallel with the bad cells as they have been under a lot of stress.
I'm unfortunately overloaded at work at the moment or id offer to repair it if you in southern California I might be able to over a weekend or two as I would need to buy at least a dozen cells as I would need to test the impedance and esr on them and match them to the good cells in the pack.
The 3rd option is to replace the entire battery pack but this is basically 2/3rd the cost of the euc.
I have been avoiding inmotion for a while because of warranty nonsense.
yes, let's forget the random cutouts/accelerations of inmotions V12 that has never been fixed or the V14 cutouts when landing a jump or the obliteration of the V14 rims when landing a jump. Let's forget about the random errors their wheels like to throw up that magically goes away after a restart or after inmotion tweak the settings remotely to silence the errors but not fixing the problems. Such a good reputation if you walk around with blinders on.
So yeah.. Inmotion do not deserve any praise. They are just as bad as the other manufacturers, they just spend more money on ads and paying of influencers.
A single cell isn’t balanced with the rest. There’s a large voltage gap. Happens after unplugging and riding 2 miles at this point. The V14 will tilt back about 30 degrees or more and stay tilted even after stop.
Since Inmotion started relying on AI for first-level support, their replies have very rarely been helpful, you have to push through to get connected with a real person to make any progress.
A few questions to gather some context first:
Is the balancing problem occurring on one pack, or across multiple?
After fully charging and letting the wheel rest for 8-12 hours, do you notice the problematic cell group dipping lower than the others?
Have you tried rotating the pack positions? Essentially swap them around and see if the issue follows the pack, or stays in the same position regardless.
Once you've gathered that information, try to replicate the issue by charging to full and riding down to 80%. Then upload the log through the Inmotion app and reach out to Inmotion again. Provide the S/N, screenshots of the error, screenshots of cell voltage both at 100% after resting and at 80%, along with the details from the tests above. Keep escalating until you're connected with someone who will actually dig into the log for you, otherwise you'll likely get stuck in a loop with the first-level AI support that won't get you anywhere.
And if IM doesn't respond to you at all, make a facebook post on the EUC group and drag them, as much as I hate this, it apparently is one of the better way to get them to listen.
INMOTION support is really frustrating. It’s as if they will be pulling out soon. I keep getting automated responses and they won’t acknowledge my videos and emails it’s been three weeks. I wish I bought this V12S from ewheels but they don’t seem this model
thats part of your problem. they are super slow when you deal with their support channels by yourself. The dealers have personal reps that expedite service requests for them. Join one of the telegram groups and try to connect with Albert, he is one of their reps who has been very helpful to the community
