Hi
I got a dual battery setup which I’ve been using for a couple months now. Since installing cloudwheels I noticed something odd.
After under 10km (usual range at least 20) the remote starts vibrating indicating battery is low and it stops taking throttle. But when rolling again the battery indicator jumps back up sometimes around 10v, usually from 44v back to 50v.
I know this is normal but when I touched the batteries after my ride I noticed the one that I removed a couple days ago got warm and the other didn’t. Is it normal for the battery to heat up while riding?
Asking so I know which battery enclosure I have to check.
My thought is either one battery is not connected properly anymore and thus doesn’t heat up or the other one heats up because of some malfunction maybe shorting somewhere
I would guess you came from smaller wheels and now are pulling more amps in order to move the bigger wheels? Is the battery made in China? Sounds like (and I’m speculating here bc I haven’t seen the inside of the pack) the series connections can’t handle the current and are creating heat, hence the burn marks You may also have some broken welds. I wouldn’t run that battery any more if I were u. Have you looked inside the battery enclosure?
Should have said the charging port blew while inserting the charger from a bad angle.
The battery packs were bought so I haven’t build them myself.
The ESC settings are the same as before if you meant that by pulling more amps.
Battery is 2x 14s2p could send you Fotos but they’re shrink wrapped in that blue stuff
Do you have enough knowledge and comfort to take the shrink wrap off and measure p-group voltages and check all of your series voltages? If you don’t know anything about battery packs I would get someone else to look at it.
I think I can get those from the Mechanic I work for.
Looking at the charging time one battery must be dead or disconnected it recharges roughly half the time it used to and the battery doesn’t warm up while charging, is that a good sign?
Also check voltages from the 1st group progressively to the last. Measure from main neg terminal to pos on cell 1, then 2 etc… All the way to 14. You should get progressively higher voltages as you do each new cell.
Take lots of pics, especially if you see burn marks anywhere. Clear your work space of all metal. Use a plastic or ceramic knife to remove the shrink wrap. Cover exposed connections when not in use.
