There are lots of recurring themes in this thread haha sometimes we all forget what's been posted or not. Like that Midas ad that I posted and got re-posted, awesome.

Now is that existing DC-DC converter going to handle the added current draw? Is it integrated into the speed controller? I have to say my extent of experience with repairing electric golf carts so far has been just replacing GC2 batteries.

Good morning enthusiasts, the topic for today is rain, I hate rain in the winter, what a mess out there ....

Hope y'all have a good day

 

Good morning fellas.

@Gig. Yesterday was a drizzly day. Last night was a monsoon. And 54 degrees now. Man winter is a pain.

 

I agree Paul, big mess up here....

oh well, we always get a January thaw

 

Howdy guys


That is the issue... it does have a 36 - 12V converter but not nearly big enough. I can't get one big enough that I know of (70 amps) and I am not sure how it would work with the load changing and spiking so drastically. Not sure if a converter would handle it.

Option 1 - run the amp off of 2 of the 6 existing batteries and charge the system 2 batts at a time so the other 4 don't sit and boil while charging.

Option 2 - put in another 12V batt just for the amp.
(prob what I will end up doing)

IDK yet, gotta take another look at it.

Have a good day everyone!!

Good plan Darren, have a good'un

 

Good morning guys!

We got freezing rain last night. Like a lot of it. Wife made it home from work and got 3/4 way up our driveway and slid down. We live on a hill. Her Acadia has AWD, but there was just oo much ice and not enough sand as the rain washed it away or froze on top of it. Truck was teetering on two wheels when I saw it initially. No pics (raining hard). It took an hour and a half, 200 lbs of sand and a superduty to get it out. No damage (other than a scratch on the frame where is was teetering on a rock)! Wife did great and remained calm. She is so awesome...

 

Wow Savage, glad u got her up the hill safely and all is well !!

Glad to hear she's Ok & all's well now, that coulda been a lot worse huh

 

Nice work Andre

 

Darren, a single 12v works, but not for long with the current draw you are proposing. My cart is setup with a head unit and a 4x35w amp with 4 each 6.5" JBL speakers. I have a stand alone 12v battery to power the system and lighting on the cart. I can run the system pretty strong for maybe 3 hours without taking the battery below 70% SOC. When we take it camping, I have a small 10 amp battery charger that I take along to charge the 12v battery every night and sometimes it gets a boost at lunch time.

I don't know if it will happen this year, but I would like to upgrade the controller and jump up to 42v instead of 36. When that happens, I will eliminate the standalone 12v and use a converter for my 12v power. Not having an active charging system on the cart really limits your 12v capacity. I guess you could always add 2 more 6v cart batteries in series to get more capacity for your audio system.

 

Good morning gang, happy Saturday!!

Andre, Glad everything turned out good, sounds a little scary.

We had some rain early this morning but just a bit breezy now and 45°

Have a good day guys, Cheers!!
