This is a thread where you share stuff you have returned. Please share your story.
I bought 2 of these and a charger bit ago, but realized that I want more speed, less weight, and a smaller form factor. These batteries were running my scooter. I was running them in series to obtain 24 volts. The scooters original running voltage. However, I’ve replaced the controller and can overvolt it to 36v. The higher voltage will give me more speed. Along with that, I’ll have more capacity/range. All the other scooter that I’ve been looking at, run at 36 volts. I’ve been looking because I really like the scooter and want something faster/stronger. It’s cheaper to upgrade the battery, rather than buying a whole new scooter. The old setup was 24v 18ah, the new battery that I’ll be getting is 36v 20ah.
The only downside to overvolting this scooter will be that the controller and motor will get hotter faster. The controller has a low voltage cutoff at 20v. A 36v battery will get damaged if drawn that low. Probably can drain to 35v before start losing power. 33v would be the danger zone, accounting for voltage sag. I’ll be installing a voltmeter to monitor my usage.
Since the scooter was free (found it in a pile of trash off the freeway). Story. I don’t mind if I blow the motor or controller. If I do, then I’ll upgrade from the brushed motor to a brushless. A new motor with controller would be about $100. I’ve already installed 3 12v SLA batteries to test the speed, and I really like it better than at 24 volts. Just yea, I’ve got to be mindful of heat buildup.
Have you returned anything? What was it? Why did you return it?
