The pack I chose was a Zippy Compact 7s 20c 5Ah battery from Hobby King. The LiPos I planned to use had a 20c rating, which meant that they could handle 125amp of discharge current, and since the scooter is limited at about 30amps it meant that I would have lots of headroom/safety margin. appointments and such) only survived for about 6 months. Plus… The Gell-Cells have poor current handling ability, and in my experience of almost daily use (for shopping and Dr. It occurred to me that the two heavy lead acid gell-cells, with a drop dead voltage of 22 volts, could be replaced with 7 lightweight 5000mAh or 5Ah LiPos with a drop dead voltage of about the same voltage (22.4V), and the low battery light would still be useful.

EZIP 900 BATTERY FULL
With gearing mods, he’s hoping to eke out some more performance.Īfter the break, the full conversion video. The $200 scooter now does 28 km/h, up from 22 km/h and charges much faster. We’re not saying it’s advisable to disable all current and voltage limits on your scooter, but it seems to be working out for.
Cutting the trace to the TL494’s current sense pin removed the current limit all together. This motor controller uses a TI TL494 to generate the PWM waveforms that drive a MOSFET to provide variable power to the motor.
With the voltage issue sorted out, it was time for the current limit to be modified. The solution: disable the safety shutdown relay on the motor controller by bridging it with a wire. It refused to start up with the higher voltage. The original batteries only ran at 24 V, which caused some issues with the motor controller. Each provides 18 V, giving 36 V in series. The new batteries were sourced from a Ryobi drill. After getting tired of the low speeds and 12 hour charge times, decided it was time to swap for lithium batteries. had an older Razor E300 that uses lead acid batteries. If you don’t mind paying a little more for the 15Ah version you will receive a higher capacity battery, which can offer you a longer runtime.There’s a bunch of different electric scooters available nowadays, including those hoverboards that keep catching fire. In summary it is all a matter of your preference. Keep in mind that in most cases as the Ah rating goes up so does the size of the battery! As long as the battery you want to replace has the same voltage and dimensions it is okay to substitute it with a different Ah replacement. Amp-Hours basically show how much energy a battery holds. Check the data sheet to make sure they will fit your case. Please note that some 15Ah batteries are slightly taller. As the dimensions of the 12 Volt 12Ah battery and the 12 Volt 15Ah battery are the same, they are interchangeable. Simply put both versions will fit in your application and will work fine. What is the difference between the 12Ah battery and the 15Ah battery? Why would I upgrade?
