# Circuit Replacement for a Go Motorboard Answered

1. I have an old Go Motorboard scooter that the circuit for charging the battery and managing the power to motors is burned out. I have a rudimentary understanding of circuits and how to build them. Can any one recommend a resources to learn how to build a circuit that can charge the batteries, then apply the power to the two motors activated from a throttle. https://scrabblewordfinder.vip/https://www.applock.ooo/https://www.7zip.vip/

OR where to buy a replacement control board?

You might want to look at the "Main Page" of the motorboards.org wiki, here:

In particular, the sections labeled "Trouble Shooting & Repair" and "Replacement parts directory," I think, might be useful to you.

Regarding your questions about how to build a circuit that can, "charge the batteries, then apply the power to the two motors..."

These functions are usually handled by two different circuits, namely a battery charger circuit, to charge the batteries, and a PWM (pulse width modulation) circuit, to throttle power to the motor(s?).

Also there might exist a module attached to the battery, there to protect it, by disconnecting the battery, in cases of overcharge and overdischarge.

Speaking generally, you will see sort of the same floorplan in many electric power tools. That is: you have a battery, a motor, a PWM module to throttle power to the motor, and you also have a charger module, for to charge the battery.

Also speaking generally, the facts you want to discover first, when contemplating the overhaul of this whole, uh... energy delivery system for your scooter's motor.

How much power (in watts, or volt*ampere product ) does the PWM have to deliver? And at what voltage (in volts)?

What is the nominal voltage of the battery, and how many cells does it have stacked in series? Also what kind of cells (i.e. chemistry, e.g. NiMH, or Li-ion, or whatever), since that determines the kind of battery charger needed.

I think motorboards.org's "Repacement parts directory" included a link to BatteryUniveristy.com,

http://www.motorboards.org/index.php/Replacement_p...

http://www.batteryuniversity.com/

and that is a good place to go if you want to learn more about batteries: How to build them. How to recharge them. And similar topics.

You get motor speed controllers for all common voltages on these scooters.
Same for a battery charger, depending on the battery system, E.G. NiMH or Lithium cells.
But depending on where you are it often comes cheaper to buy a new scooter...
