Default CC DS 4-12v to 6-8v conversion

Here is an overview of a decent (in my opinion) DS 4-12v to 6-8v conversion with adequate hold-downs, and no cheezy lumber or other bs.

Materials needed-

- 4 of your original hold down rods for reuse
- 2 of your original plastic hold downs for reuse
- 4 standard DS 8v hold down rods w/ nuts and washers (i used yamaha G22e rods, i had them on hand)
- 2 DS 8v plastic hold downs
- 2x 15" lenghts of (2"x2"x1/8" aluminum angle)
- 4x 13.5" lenghts of (2"x2"x1/8" aluminum angle)
I used a chopsaw with 1/8" kerf, so my angle may have been slightly shorter.
Angle aluminum was available at local hardware store.
- 12x 1/8" pop rivets
- 6x 8v batteries of your preference.
- your original cables for reuse (or new cables for 12v DS)
- will also need 2 additional cables (marked red)

Tools Needed-

- air hammer with chisel far easier, or hammer & chisel
- chopsaw or hacksaw for cutting aluminum angle
- rivet gun for installing rivets
- 13/64" or 1/8" drill bit for rivet holes
- drill bit for hold down rod holes, not fussy, just bigger than hold down rods
- drill
- cable & ends for 2 new cables

Steps-

- remove 12v batts and extensive cleaning
- (air hammer chisel) remove 4x spacer brackets (circled green)
- (air hammer chisel) remove 2x support brackets (circled blue)
- use 13/64" bit for rivet holes on next 2 steps
- install 2x each outer battery bay, 13.5" support brackets with 7.5" spacing inside to allow 1 battery to rest inside.
- install 2x center battery bay 15" support brackets with roughly 10.5" spacing from center bracket to allow 2 batts to rest on each side of center bracket.
- set a battery in tray, mark locations for new hold down rods holes on center brace and new (15") brackets.
- remove battery, drill new holes for hold down rods.
-Install batteries, hold down rods, and cables.

I configured the batteries this way for my convienince in cable routing (i had to cut out a corroded portion of main positive cable). You may configure your batts however you like. The 4x 12v ds has no voltage reducer, i used a simple method of automotive resistor wire to reduce voltage, a dc/dc reducer would have been nicer, but i didnt have one.

May I ask a rookie question, why would anyone want to convert from 6 8v to 4 12v batteries, is there a major difference?

It's the other way around, 4-12v to 6-8v. The 8v batts produce longer run times as well as longer pack life. A 12v pack typically doesn't last more than 3-4 years where an 8v pack can last up to 6 years...

I was reading several threads about converting, I looked at my 2008+ precedent, it is very tight with the 4 batteries, you think I could convert this to 6 8v? My brothers ds has lots more room, although he has 6 8v batteries already. It just looks really tight in my cart to try to do that.

Yes, your compartment is too tight without modification. So.....there is another "stickie" with photos as well as a great write-up specifically about converting 2008 and older Precedents to 8v batteries. Its a number of pages long but is very specific. If I buy an older Precedent, that is what I will be doing.

Yes I read this one, Mine is the Newer 08, slightly different but maybe I can make it fit, the controller isn't in the middle of the batteries. My next question maybe you can help, this cart I just got has 4 new Trojan 1275,s in it I'm assuming I should wait it out until I need to replace them then do the upgrade. I'm asking this because in the near future I'm upgrading the controller and motor so I can get more torque, I use this cart in very hilly area and on gravel roads and some dirt. maybe I should start a new thread.

Yes - we shouldn't occupy sticky section. If I were you - yes, I would take as good care of your 12v batteries as you can (no point in being wasteful) - Then take the plunge when you have to. Only run-time will be affected with the swap out when it happens. I use a battery maintainer - some of them are very cheap - you might consider buying one to get the most out of your batteries. I really can't say it will help extend their lives - but could it hurt?
