|
|
So as with anything I own, it's not quite right until I alter/customize it in some way. My daughter/son have a 12v Peg Perego John Deere Gator (which I would have given anything to own when I was a kid), after 4 years the battery is toast. So in the process of buying a new 12 v 12ah battery, I bought an additional 6v 10ah (Is it ok to have different ah when run in series?) battery (this is the turbo boost). Many conversions like this have been done, and although the motors receive more power, those that have done it haven't burned them up, it's when you step up to the 24v that fries them. Anyways here is my question, I want a "NOS" switch that my kids can turn to kick the 12v to the 18v power supply to increase the speed. The suggestion from others is to run the batteries in series, which makes sense, but I'm trying to figure out the wiring. There are a few threads online, but no real conclusion is drawn from them..
Initially I'm thinking I obviously need to use a switch and relay, but never really worked with DC like this before, and have no idea how to wire. I've included a rough sketch below. A few questions.
1. Is the fuse set in the correct spot
2. What switch parameters do I need? (18vdc? How many amps? Basically looking for a specific description of what I need to buy)
3. The relay (I believe this is a Bosch type, I've been known to purchase the wrong item online many times before so a link in the answer would be incredible)
4. Is the difference in amp hours ok? I have separate chargers for each battery.
When this is complete, I'll post pictures, but for now, any wiring help would be much appreciated. (I think I might enjoy watching this work more than my kids will enjoy tearing up my grass!)

Just as a followup. I went with a simple 24 v switch. When off, the 12v runs the car and it runs a normal low and high speed. When on, the additional 6v kicks in and the car cooks. 18v Gator is pretty fun. I know my son had a huge smile on his face as the wind ripped through his hair. Anyways, Kal, et al, thanks for the help.
