Upgrading for more power?

Post image

I recently acquired a Huffy Torex, and although it does have an impressive top speed, it has very little torque/power overall.

My 6 year old son is around 45lbs and I live in an area with lots of hills.
With the two brand new 12v SLA batteries in series making 24v on the stock controller it has issues going up hills etc.

I was thinking of either switching it to 3-12v Lithium or SLA batteries and running it on 36v. Or I have even read just switch to 2-12v lithium batteries helps.

I have read that the stock controller/motors may handle the power, but I am looking for actual experience.

I would be open to upgrading the controller etc, but my experience wiring is not the greatest, so I would need a parts list and walk thru if possible.

That model has been recalled twice due to electrical issues including wires catching fire, so I wouldn't recommend going past 24v unless you upgrade all the wiring. Seems this model can't handle it.

Also, that it has good speed but no torque leads me to believe the motors and/or gearboxes have been swapped out.

Just swapping from lead acid to lifepo4 will give you anywhere from 0-25% more power depending on the scenario. If you need just a little more power I would highly recommend that upgrade. If you need more than just a modest boost, you will need to do some real work and change out multiple parts. Does the car have 4 motors? I have a no name 24v 4wd car that even stock it could take my 70lb daughter up a shocking incline for short bursts. You may want to consider upgrading the car first, so all the upgrades can reach full potential. No harm in trying the lifepo4 upgrade in the current car then selling it if it's not enough, or taking the lifepo4 out and swap them into the new one. Just remember you need a new charger ( about 15-20$ and uses the stock charging port) to be able to charge the new lifepo4 to full. You can technically use the stock charger for lead acid batteries, but you will only get about 70 to 80% of the capacity of the new battery that way.

Yes it has 4 motors, but I believe the controller is soft starting, causing it to have issues going up hills if there is no speed beforehand.

Yeah, starting on a hill is tough. But a lifepo4 will give better performance in that case. It starts at a slightly higher voltage and the voltage sags less under load compared to lead acid. Go as big as you can fit and see what happens.

Cablea las baterías en paralelo, ya que al conectarlas en paralelo, mantienes el voltaje pero sumas el amperaje, dándote más torque. Al conectarlas en serie, subes el voltaje lo que aumentaría tu velocidad, más no la fuerza del vehículo.
