The controller will give you added speeda and larger tires or gearing. Nice install. I'm getting ready to change mine out. Have a navitas controller and a red hawk motor. Currently going 21 with 10 inch tires. Just hard to get up to speed and sustain uphill speeds with the old Trojans.
Thanks, yes, I thought having it under the cart to allow it to not be in the enclosed area under the seat and allow air to pass by it to cool was smart. Just cant go 4-wheeling and let brush rip it off the bottom!
Forklift Nations’s amazing custom build Yamaha Golf cart powered with BigBattery Eagle Lithium Ion Phosphate batteries replaced 496 lbs. Trojan T105 for only 38 lbs. per battery. Powers 4x of powered performance, 4x in total in range, drop and replacement of GC2 lead acid no special mounting bracket and 10 year full warranty. #batteries #golfcart #lithiumbattery #BigBattery
Cool video. I did the same thing to a Club car. I used 4 BDGR 48v L Ions. You will see a big improvment in range, mine doubled. Aslo cart will climb hills better being lighter. I would cuation using the stock charger. I know what Big Battery says on their site, but my stock charger almost fried my $2500 worth of batteries. BMS stopped it from over charging. Get a good L Ion battery charger.
I'm a good i guess mechanic and alctrition myself and I gotta say you did a pretty good job like I'm looking at the fuses of stuff usually it all looks like a giant mess but you did it amazing and for and for the mistakes you made those are just regular mistakes I mean I would make them as well sometimes and if or sometimes and if you ever need advice I would be willing and capable of helping
Appreciate the atta boy and will keep you in mind if and when I do my 2nd youtube video. But damn! All the editing and stuff ! A lot of work or perhaps that was just the learning curve to do all that stuff the first time. Anyway thanks dude!
I’m a bit iffy on the charger working with this. Unless the batteries are smart enough to fake themselves like a lead acid battery. They have very different chemistry so should have very different charge regime.
I have a Yamaha G9e 1994. I want to upgrade it from 36v to 48v. Mine was missing it’s original harness. Can I use any 48v wiring assembly? I have a Curtis controller 500a, new solenoid 48v and a lithium battery. But my cart has many more wires than yours, forward reverse l, accelerator, ignition etc. I can’t get any power with the wiring I’ve tried. So maybe I need a whole new harness? It came with a wiring harness that was spliced and diced many times over. The original G9e has two diodes which this harness I have doesn’t have. Idk if I can skip those and just connect to the diode on the solenoid
Good to know. I was concerned about heat build-up messing with the electronics (I assumed there are some inside the unit) and played it safe. That said, I was also concerned about a branch or something else hitting it while driving over different grass and curbs, etc. But so far so good. Thanks for the comment!
Great install and video! Couple questions for you, you can use the standard 48v charger on it? Also what was your top speed prior to install? Do you have the PTV tune on the controller? My 2008 G29 tops out around 12mph currently.
Yes the charger in the video is the 2007 charger the guy I bought the cart from had. Not sure about the controller, but think it was upgraded before I purchased the cart as the cart did 17 to 18 mph prior to this battery change out. So there was no change in top speed, but the acceleration appears to be a bit better.
How much did you end up spending? I’m looking to buy 2008 for 3k then upgrade it to lithium battery but I’m not that great on doing wirings I’m going to need your help
The batteries at the timer were about the same as buying new Trojan's at $11-1200. So I would say another 2-300 for miscellaneous stuff and of course my time. I spent about 40 hours.
You probably don't. But it was all I could find that had a cover, fuses, and terminals that fit my area that I wanted to put it. That said, with a proper fuse on each circuit, I dont see any downside to having an "above needed" capacity on the allowable amp capability of the housing like I have. Do you?
@@Builditright I agree, no downside. I was worried that I was going to go too light because I've struggled to find good info on the minimum amperage it needs to cover in this situation.
That is 250A @ 12V which comes to 3000W. 3000W @ 48V is 62.5A. I believe the motor in these carts are 2600W so I do not think he has as much headroom on the busbar as you might think.
Turlock CA as well... installing my lithium today and was caught off guard hearing Woodys in Turlock mentioned 😅
Good people!
Good job Jim. This makes me want to upgrade my Polaris EV

good video!! great idea on mounting the voltage reducer underneath.

Cool. Hope it did well for you and was ok given the different cart manufacturer.

Can you do a range test?
No need to have air flowing over the converter. They are always mounted under the seats.

With this setup do you have around 96AH? What kind of range are you seeing between charges? Any issues since install? Thanks again in advance!

I'm going through the exact same G69 Lithium upgrade currently myself. I'm wondering why you used such a large busbar at 250A?

Listen man it's a good video but you have to stop smacking your lips when you start your sentences
