16v battery replacement

[sturgeon866]

Hi Everyone,
My son have a Kidtrax SRT Viper 16v. Unfortunately the battery died. Worse of all manufacturer does not carry the battery anymore. I have looked everyone for it and seems the only palce I find it is in china with 400$ freight (which is almost twice the price of the car !)

So here's my question, I plan to put 3 x 6V in series to give 18V or 2 x 12V. Any advice on what to look to see if the motor will handle the extra power ? Anything on the little board ? Any advice ? I got good skill doing the wiring and knowing basic electrical thing (Parralel wiring, Series, AH calculation, charging) but motor parts is something new to me.

Thanks

Hi All, me again.
I have decided to go 3 x 6v total 18v to play safety. So far everything is working fine and my son is happy again ;)
Everything runs fine and no major bump in speed. I find out the the small board is a relay. Still do not know what this is doing exactly.

So in case other lucky SRT Viper 16v owner are stuck with a dead battery 3* 6v 12ah seems to works fine.

Hi,

Thanks for posting that 3 x 6v battery works on the car. I am new to this and not sure how can I connect the batteries and which batteries are required. If possible, can you please post a picture of your setup or a short tutorial. and if you can please let me know which 6v battery you used? From where can I buy these 6v batteries?

Thanks

Hi Neudar,
Here my picture. Remember as disucssed that I do not have fuse to my setup currently and you should put 1 on each battery. I will do it as soon as I received mine.

Thanks a lot. This will really help. Whenever you receive the fuse, please post some more pictures as well.

[sturgeon866]

I will, but this can take a while. I ordered some but seller (china one ...) sent me the wrong item. so I got another 3-4 weeks of waiting.

But in the meanwhile here's the diagram (And you will see how good am I with paint !!)

Sturgeon866,
Wondering how your car is running now? I have the same predicament. 16V battery in Viper is dead. Cannot find replacement. I did find a guy out west
who will build a 16V and sent it to me (Pacific Cycle sent me to him). Or, he tells me that I could simply put in a 12V and it will run a little slower.

Did you try 12 V only? If so, how did it work?

What are you using to charge your 6V batteries? Not the original 16V charger, correct?

Thanks!
Brian

Hi HunterAce,
Car is still running fine, but I am still waiting for my inline fuse so I limit the play time with it. Battery life is good as before, I did not notice any change in speed. I did not try 12v as I did not want it to go slower.

To charge the 6v battery I am using a 6v Battery charger. Before I made my power pole connector I was charging them one by one (that mean unplugging them everytime ...) but now with my power pole connector I charge them at once in parrallel. Take about 30h if they are depleated but since the charger I use stop when full (opposite of the original one provided by pacific cycle ..) I charge the car after every use so it is always ready to go.

I forgot to ask, How much for the custom made 16v ? and what about the shipping, this thing is heavy...

[HunterAce]

Thanks for the reply! I was told $125 total for battery/shipping. LEVT (Light electric vehicle technology) is the name of the company. 1-877-807-5388. I am in Indiana. They are out west somewhere.

Hi
I am using a SRT to make a RC Lawnmower. I am using 2 x 12v 20 amp hr. Can anyone tell me what the wattage of the motors are?
