Winter upgrade to 48V

shaferz

Hey all -

The 36v batteries we have now are on their last legs. Fault of my own - batteries were neglected a few times and plates were left exposed. No good.

At any rate - it has come time to consider new batteries. Seems like prime time to make the jump from 36V to 48V.

Its my understanding that at the DCX400 can run on 48V. AMD Motor should be able to run on 48V (?)

I do not have room for 6/8. I will need to do 8/6. So batteries, and IIRC, a new solenoid is required. Makes sense to go to 2 gauge wires at the same time. Plus a charger. I realize the DPI is highly regarded from ScottyB, but I was hoping to find a relatively good priced on board unit. If DPI is really that much better, then that may be the answer.

Anything glaring that I am missing?

Upgraded battery cable set is a great idea.

I think you have your battery concerns transposed. You want 6-8v batteries if room is a factor. You will also need a 48/12vdc voltage reducer to run any 12v options. The DPI chargers are the bomb. My work has purchased three of them so far. They even tell you when the wall outlet is dead (GFCI tripped for no reason).

I know a good battery house in Illinois, depending on your location. Illinois is a big state!

I would not go with an onboard charger. They don't really hold up all that well with all of the vibration and they take up valuable space.

My experience as well. I attribute the early demise of on board chargers to 2 things.
They are always pulse wave chargers not good ole reliable transformers.

The cart environment is hazardous to the chargers existence when you factor in the heat, the dirt, and acidic vapor it's no wonder they expire before you expect.

Gornoman... Yes. Correct. :) My mistake. I can house 6 batteries, not 8. Golf bag well is occupied by a subwoofer, and I have a separate 12v Optima Blue top under where the driver sits to power lights and stereo.

I guess I just liked the idea of a on-board charger - but sounds like DPI is definitely the way to go.

So...

6 batteries (still need to decide on brand)
DPI Charger (from ScottyB)
2 gauge cable set (from ScottyB)
Super Duty 400a Solenoid (from ScottyB)

Anyone know off the top of their heads the procedure for getting the DCX400 switched to 48v? IIRC, it is a setting in the software, but can I change it to 48v while still connected to a 36v pack? Just wanted to make sure I wasn't going to fry something due to an incorrect software setting for pack voltage :)

also, every DeltaQ i have seen installed under the seat (or inside dash on gem) is always in "thermal cutback- reduced output" due to heat buildup under the seat. if you decide to go with a charger under the seat, please prop the seat up while charging to allow heat to escape.

Factory default settings on DCX allow 36 to 48 v operation without any change.

Bump.

:) Spring is almost here (along with my bonus check) - so its time to make some decisions. Going to 48V is confirmed. So I am looking for 6 8-volt batteries. I have no need for a 12v converter - I have a separate 12V Optima that is used for my 12V stuff right now, and do not want to veer away from that.

Any recommendations for 8V batteries? The 6V units in the cart right now are US Batteries. 1800XC. Here are the specs:

Data:
20 Hour Rate: 208
Minutes of Discharge @ 75 Amps: 107
Minutes of Discharge @ 25 Amps: 392

Length: 10 1/4” (260mm)
Width: 7 1/8” (181mm)
Height: 11 1/4” (286mm)

If I stick with that brand, I am assuming i would go with the 8VHATB XC2. Here are the specs on those:

20 Hour Rate: 205
Minutes of Discharge @ 56 Amps: 164
Minutes of Discharge @ 25 Amps: 435

Length: 10 1/4” (260mm)
Width: 7 1/8” (181mm)
Height: 11 7/8” (302mm)

So, longer discharge and juuuuust a tad bit taller than the current batteries. Are there better options out there for 8v batteries?

TIA!

I have herd nothing but good reviews of the Trojan Ranger 160 batteries. I am picking up my set on Monday.
Just my .02 cents.
