Wanderer max PV input is 25V, so your panel is too high. Growatt would need at least 60V from solar to charge 48V battery, so at least 2 panels in series (3 probably better). I would do 2 strings of 3 panels in series into the Growatt.
EDIT: I just checked that Growatt spec sheet. Man, I wish I...
Bought a surplus DOT sign trailer,
converted it into a mobile solar powered LiFePO4 system to power our school audio system for concerts outdoors and at venues with low-quality electrical connections. System originally had 8 4D flooded batteries with a PMW controller, all off 12V. Still using...
FYI, that Club Car ERIC charger can be updated with a USB disk to a new charging algorithm. There are ones out there that can charge lithium, but it goes to the peak so your BMS will likely be disconnecting regularly.
I posted my thread after you had yours up. I had made my purchases months earlier, but I didn't want to recommend before finishing and making sure it worked!
My biggest recommendation is to top balance the individual headway cells, and IR match them. Don't trust that the initial setup is well...
Thanks! Switching to good 8ga wire and instantly it went to 10amps. Even good new 12ga with proper ring terminals only allowed 5amp to flow.
Any worries about that vent being raised?
Update after 2.5 years. Pack hasn't been used much, and certainly not tested well. Capacity was lower than expected, Daly BMS is crap, and I didn't know what I was doing when I build this. Here is a picture of the swelling that has occurred. These cells have never been outside of voltage or C...
Yep, that’s how I’ve always done thing. No debt ever except mortgage and while I would love to keep it that way (and pay off the mortgage even faster) my wife gets a say and she wants a car. I don’t want to use $40K in cash, because that’s the emergency fund.
So if I’m compromising with my...
Hey all, with the low prices and a much larger paycheck than before I'm debating purchasing my first new car ever. Model 3 is tempting to me even though I've always had manual transmissions and don't love the company/leader. Any thoughts on the cheap "partial-premium" interior vs getting a LR or...
Anyone have experience with a BMS like this?
JBD (same as overkill) 300amp relay BMS. I have used 120A BMS before, and understand adding a separate relay. Just wondering if anyone has experience and has used this with a stock CC Precedent motor and controller. Will be building my own battery...
Yep, just put the good one in parallel with the bad one. I would do it one at a time, and would go low and slow. Like 5Amps. Seriously though, it is almost certain you won't get a good result, and may mess up you PB battery or system.
Finally finished my pack, using battery hookup “super beast” modules. These packs are 24V each, using 6P8S Headway LiPO4 cells. Resulting pack is 96 cells, total of 48Ah 48V nominal. Using a JBD 300A BMS, giving me Bluetooth monitoring, low temp cut off, and all necessary protections. Club Car...
There is probably a better way for me to link to this... https://diysolarforum.com/threads/golf-cart-headway-pack.42822/
My issue is after running the back down I will have 1 cell is a pack far out of balance from the rest, so the overvoltage protection triggers often when trying to recharge...
12 PD+ (US Battery US8VGCXC2) batteries, 4 Napa 8274 4D batteries, and 4 Interstate SRM-4D batteries.
All batteries are between 3-6 years old. Batteries have been on either golf cart charger or solar maintainer every day for their entire lives.
Scrap value is $0.25/lbs, so any offer over that...
Edit: After thinking for a minute I noticed you said these have been drained for months. You will most likely just damage your good battery trying to save these. Take them back for scrap. Where are you located? If it doesn't get very cold, this could be a perfect chance for a salvage DIY lithium...
First, welcome!
Next, Battleborn is in another stratosphere for quality and reliability than these Amazon companies. They are not at all the same product!
That said, your use case is probably fine for the cheap stuff. I think Amperetime and Chins are ok from what I understand. I would want to...
another option, look for a place that sells reconditioned or used batteries! There is a store local to me (other cost I'm afraid) that sell the Armasafe Hawker AGM batteries that the military cycles out. They have them in different stages of life, and are amazing deals!
You can use some rubber bushings on the mounts to ease some of the vibration concerns. What is your shade scenario? Will you have any vents, decks, racks, or antennas on top of the roof you need to work around? If you are in unshaded parking most of the time, go for the highest series voltage...
Amps are more for acceleration generally....

Anyone know what kind of connector this is, and where I could buy it? 48V, 10AWG, F2 on the other end (but I will change to XT60).
Model is 5P1500RT
Thanks!
The other thing I learned, holy goodness is the swap worth it! Much faster acceleration, better performance going up hills, no more voltage sag sadness, lightweight helps everything (Thanks Colin Chapman), and I love my storage compartment under the seat. I got back half the cost of doing it by...
Did you ever finish this? I used 2 superbeast for 48V club car precedent. I went with a 300A JBD bms and am happy with it. Not as happy with the headway balancing….
