Winch Fix for Lithium Battery Setups
Вставка
- Опубліковано 2 жов 2024
- Lithium battery setups for hunting carts pose a challenge for those who need a winch. The challenge comes when trying to run an amp hungry winch off a 12v regulator that's not made for high amp delivery. Trying to make this work can potentially harm your lithium battery pack if you are not careful (I blew a battery...I know!). To my knowledge there are no 12volt regulators that can safely deliver high amps for golf cart winches. The only solution at this point is to run a separate battery to independently serve the winch. Now that my winch has it's own battery it runs like a champ and the onboard charger makes charging painless.

I watched your prior videos saying your cart is a 1982… which would have been a resistor setup. I have a 1989 DS I am building and want to concerto to solid state also. What pedal box did you use? Did you even use a pot box? What wiring harness? I see you used an Alltrax controller. Did you pull everything out of a newer cart? And do you have a Run/Tow switch? Your FNR looks like a standard toggle? Thanks in advance for the info!
Hey brother. Yep, ripped out the entire resistor setup and started from scratch. I use a PB-6 pot box. I didn’t use a wiring harness, just wired as needed. I don’t have a run/tow switch and my F&R is a heavy duty upgrade but a simple toggle. Hope that helps and have fun!!
Would it be too much trouble for you to sketch up a quick diagram how you were able to wire in a controller and petal box with your Plum Quick motor? Snap a few photos? Even make a video?!?! It would get a ton of clicks. Building golf carts is hot right now and there are a lot of people with the same questions I am asking. Let me know if you need my email?
I keep my cart at the farm so I don’t have it here to sanp pics. You can find a lot of Club Car wiring schema online for a custom series setup. That’s what I used. It will diagram all the wiring for you using a pot box, etc. There’s a bunch on Google. Good luck!
Your new co host stole the show… good one
would a 12v lithium battery worked? I have a 48v lithium battery and then installed a separate 12v (20ah) to hook all other lighting etc to
I wouldnt use a lithium battery because I don’t believe any of their BMS would allow that kind of amp draw without tripping or possibly damaging the battery. I went with raw lead acid because it’s bulletproof and delivers great amps on demand. Hope that helps!
I love your videos thank you for making them. I'm wondering why you don't just run a couple 12ga wires from the winch battery to your 12v buss? That 48 to 12V DCDC converter (you call it a regulator) will keep the winch battery topped up all the time. That's what full-size EV's do.
You should put a relay in one of the 48v leads going to the DCDC converter so it only comes on with the ignition switch.
I like your thinking! The downside would be that you need more than 12v to charge a 12v battery to full charge. You need 13v or higher depending on the desired speed of charge. The other downside would be that if you used your winch a lot and brought the battery way down it would take a very long time to recharge at 12v which is a constant drain on your main pack. I think full size EVs must have an auto regulator charger for their 12 volt batteries but I’m not sure. The other way I thought about was to mount both chargers onboard and then have one AC outlet for both. Being an offroad cart and my charger not being waterproof I didnt think that was a good idea. Thanks for your comments and let me know what you decide!
@@TheHandyHunter I've been using DCDC converters just like the one you're using for years and always assumed they put out 13.6V. I have one on my solar batteries right now and just checked. I'll be damned!! 12.4V. I've been doing EV conversion for a while, too and the DCDC converters we use put out 13.6V specifically to keep a 12V car battery topped up. I just assumed the small ones did that, too. For what it's worth, I just looked on Amazon and you can get 13V DCDC converters but they're like $75 so probably not worth it considering what you're using is working fine for you. Learn something every day!
Thanks for the info! I still think your method would work but it might not keep the winch battery fully charged…but charged good enough for what I need. What brand of converter do you use that runs 13.6v? I would consider that for a future build. What kind of EV conversions do you do…cars or offroad stuff? Thanks!
Having problems with keeping small 12 batteries charged with the 12 v regulator, solar panel not even hooked up to a trail camera? Set it up as shown on video. Left side of regulator goes to battery middle negitive and right side to connection to camera. Solar panel is green. When fully charged camera connection is showing the volts coming to the camera which is under 12 v. Can someone figure my problem out.
How did you wire the winch when you were running 48v
I put the winch on it’s own 12v lead acid battery. I could never find a 12v regulator for my 48v pack that could handle the amp draw. Having it on it’s own battery solved all my problems. Hope that helps.
😮😮😮👍👍👍👍👍
Another great video. Some times the easiest fix is the easiest solution. How does the cart do pulling your trailer loaded up with hogs?
Thank you! It pulls really good but I haven’t had a chance to max it out yet with a large load of hogs or wood…just medium loads. So far so good but I’m am planning on building a new cart this year if everything goes as planned. We’ll see!
With the lithium upgrade, how long does a charge last?
Mine is a 95ah set. I got nearly 25 miles on pavement. Maybe 20 offroad but I need to do an offroad test. It typically will last me all day for my needs around the farm.
Man I was hoping you were gonna do a video on this! Great setup, great video, thanks a ton! Can’t wait to get mine done
It works great now! You could probably even do a smaller lawn mower batter (UT size) with a smaller case and still have plenty of juice. Glad it up and running again! Good luck!
@@TheHandyHunter my winch is up and running! I got all the same stuff you did and installed today. Fantastic setup. Thanks again!
Great to hear!! Glad you finally got it up and running again. Thanks for all your research and feedback. Maybe somebody will come out with a monster regulator one day…lol. Until then, this setup will definitely get you out of the mud. Have fun!!
@@TheHandyHunter thanks for your help too. I look forward to seeing more of your videos, best of luck in the woods! Season wraps up for us tomorrow.
hey man, hope you’re doing well. I have the same renogy battery meter as you, does yours return to 100% automatically or do you have to reset it every time? Mine doesn’t automatically change after charging. Any suggestions?
I’m having this same issue, thanks for the video
You are welcome! Works great now!
Simple and effective. Another great one. 👍🏼
Thank you!
Great job. Nice video
Thank you!
