- This video shows the problem with the overheating of my Riden 6018 power supply and gives an update of what I've been working on. More cells have arrived. The copper bus bars have arrived and been prepped with the tapped holes for the BMS sensing wires. I have several hot topics coming up so stay tuned and I'm sorry for the quality of the video. My videographer(wife lol) will be home to help with the next one.
The manufacturer responded and informed me that an 8 amp load would trigger the fan. At 8 amps I got 5 volts at the connector for the cooling fan. I removed the fan and it didn't spin freely and smelled burned. The manufacturer said they couldn't supply a ball bearing fan and their fan should last a long time and sent me a link for a replacement fan at their expense but it was on aliexpress and would arrive in January. I ordered 5 ball bearing replacement fans from amazon for 20$ that will be here in two days.
The manufacturer has agreed to credit 5$ to my PayPal account. I find the warranty process with these Chinese suppliers to be unusual as I don't find American manufacturers asking for me to repair my own product with parts they supply unless it is stated that the warranty is for parts only. All the warranty claims with Chinese suppliers has been similar in that they want to help troubleshoot and then send replacement parts. This company has been the easiest to deal with and sending cash so I can get the parts from a local source in two days is a nice compromise. While 5$ may seem trivial and not worth my time, this exercise was done to show again what happens if you have a problem and allow the manufacturer to respond according to their process.
yes, a ball-bearing fan would likely be a big improvement, it is amazing how fast one can get things on Amazon. sometimes they are less expensive, sometimes they cost more. lots of shopping to get what one needs. again keep up the great video documentations. 😎
Excellent channel Ray. Great technical advice and detail in an easy format to watch. I have learnt a lot from all your videos. Thanks
My wife used to teach gymnastics and she always said she got paid in hugs. Your comment is the equivalent to the hugs that sustained her. Thank you backatcha.
Very much looking forward to your solution to the small size contact area on the studs...I have the same stud setup on my 230Ah cells and have also been pondering this issue. I've made my own 6x20mm aluminium bussbars and minimised the hole to get more contact area. Always getting so much useful info from your videos....cheers
I have a Riden 6012 and a Riden 6018 also (I like them, but they are kind of expensive by the time you buy all the parts to assemble them) about $175 each or so. never had the problem with the fans thankfully. I also bought a LiFePO4 charger that does about 30 amps made for golf carts early on. keep up the good work. I will watch for your videos! so we can all learn together. I think I am going to drill and tap my bus bars for the Electrodacus SBMS0 balance control wires. that is a good idea for sure.😎
When the fan fails the product dies. Poorly made cooling fans are the Achilles heel of switching power supplies. The fan supplied in my rd6018 was branded "Pengda" (40x10mm 5v) JUNK! Further inspection of the fan (pull back the sticker) reveals that it contains no bearing at all but the typical brass (probably something cheaper) bushing and a drop of oil. While ball bearing fans aren't necessary (unless the temperatures exceed +80c "my opinion") it would be an improvement over the inferior fan supplied. There is a large selection of quality fans to choose from with different bearing choices (Ball, Vapo, Hypro, Sleeve etc.) pick your flavor. Most important is the manufacturer such as but not limited to: SUNON, EBM-Papst, Comair Rotron, NMB, NIDEC, Sanyo Denki
I used this fan from Amazon "Noctua NF-A4x10 5V PWM" and these screws #8 x 1-inch wood screws (the Noctua has slightly larger holes and the original screws won't work). Just saw your first video and said that's what it looked like, now you've confirmed it.
Great advice. You often have really good input. Gems out of nowhere. Thanks!
@@RayBuildsCoolStuff Well, I have 4 of the Riden supplies, so I'm pretty familiar with them. If I could remember your user name on diysolar I'd send you the links where I purchased them from Amazon. Yes, unfortunately, I purchased a pack of 100 of the screws, so I have plenty if you need some, the fans are not cheap but certainly higher quality. Probably the "Noctua NF-A4x10 5V" is a better choice since I'm pretty sure they don't use PWM, just 5v on or off. Pretty much and 40mm fan at 5v should work, I just used butt splices and the original connector.
I used this 3 Flute 90 Degree HSS Chamfering Tool Bit Countersink Drill Bit for Metal Pack of 6pcs from Amazon. Nice massive system. I like it.
Great information Rayn thanks for sharing your learnings and teaching. I'm trying to absorb, although I won't be ready to build batteries for 10-12 years when I'm very old as in 50s already and I plan to live off grid in retirement. Is this wise? Who's going to help me build this solar set up when I'm in my 60's given I'm also non technical. You'll all be on a beach somewhere by then😌 I can most likely put the cells together. BST testing and progress inverters is not my bag. I don't know what I'm going to do?
good find, heat is usually the problem
I'm actually happy that the problem isn't in the power supply portion of the unit. That might indicate an underpowered unit not up to the task. I prefer a defective fan as the culprit for the future durability of the overall unit. I paid 200$ for this complete kit so I have some hope that it isn't cheap junk but I'm not surprised that the cooling fan is cheap junk. Does that make any sense or am I crazy?
@@RayBuildsCoolStuff lol Ray that is like putting a $20 BMS on your $4000 battery.
@@offgridwanabe yep but happens all the time on computers and such. How much would you guess is the cost of that little cooling fan? By your example it would be 25 cents which is probably correct 😂
@@RayBuildsCoolStuff You can likely get a small computer axial fan with ball bearings (not sleeved) for < $5 that will outlast the whole unit. Sleeves don't handle heat well.

I will use the money to purchase a ball bearing fan that should give no further problem.
I am sure you know this, but while it's hot like you were measuring you can meter those 2 leads to the fan and see if 5 or 12vdc is present. If it is then it's just the fan motor! If it's not present then there is a deeper problem like a sensor or a control circuit. Great work you are doing!
5 volts is present. The manufacturer says that an 8 amp load is the trigger for the fan circuit. The fan is burned up.
@@RayBuildsCoolStuff I knew you would get to the bottom of it! Much success to you!! :)
@@RayBuildsCoolStuff You know you could take that fan loose and put a computer fan (not attached) in there blowing air on the heatsink until a permanent solution is obtained. :)
@@RayBuildsCoolStuff Let me just understand this right ?:
1. There is 5V supply to the fan.
2. The supplier says that even though there is a 5V supply, the fan will only work if the current supply exceeds 8A?
3. I suspect the suppliers is BS'ing you!
4. Those 5V fans (if voltage is present) will spin *IRRESPECTIVE* of the current supply.
@@joatmofa0405 no sir, let me explain. The fan operates on 5 volts supplied by a two pin connector. The unit sends power to that connector whenever the unit is pushing greater than 8 amps. I have replaced the fan, which the manufacturer compensated me for so I could order it from Amazon and get it in two days instead of waiting for a delivery from China. The fan is now installed and the unit has operated normally for the last two days. The manufacturer was responsive and helpful. I could have figured it out on my own but waiting for their response meant learning that an 8amp load would trigger the fan circuit. I will buy another product from them.
for deburring i always use a bigger drill bit, and by hand with some little force just grind the hole clean
so for a 4mm for example, take an 8 or 10mm drill
I tried that. Even with the shallowest angled bit, by the time I cleaned up both sides, there weren’t enough threads left in the middle. I tried several methods but the fastest and least destructive was careful use of the dremel. About 20 seconds per bus bar when all went well. A lot of time was spent cutting them in half and grinding them clean for the half bus bars.
Hi Ray, have you got voltage going to the fan I am assuming it is a 12 volt device? With a pair of insulated pliers and the unit isolated, are you able to detach the cable and see what you have, when switched back on. I am wondering if there is an in line fuse feeding that fan circuit on the board or if you have a rogue joint as well as a dead temperature sensor?? Also I noticed that the new bus bars that you drilled and tapped are off centre, have you changed your planned wiring configuration? Thanks again for a great video stay safe.
As per usual, more was revealed later in the next video and the replacement fan should arrive today. The manufacturer of the power supply already deposited the compensation in my PayPal account. Good on them.
The off center holes? Well we'll talk about that in the video I make later today when my lovely videographer wakes up. I'm looking forward to this next video. We're going to explore getting the best connections with the welded studs with their small contact area. Keep coming back! Thanks for watching.
*ME :* Liked & Subbed!
Did you build that power supply, probably just get another fan to keep using it. I bought mine as a kit but haven't used it hard like you are.
I assembled the kit. I'm waiting for a response from Riden but like the post from John Emmert below.
@@RayBuildsCoolStuff they’ll probably just ignore you, measure it and see if it has a brand on it and order a few of them. I’ve seen on another form that the connector plugs into has some issues, test the back of the connector to see if it has power. I would think about putting one on the back of the power supply to pull air through it all. Hope you get it fixed, I’m charging three 5KW batteries, 24V there slightly used but are fifty pounds each.
They responded at 9pm sunday night their time and it is just 8am there now so I think I will assume that they will respond and take care of their product. They are a better company than one other that I got to replace a defective unit. That was a painful process but I suspect this will be reasonable. I'll let you know how it goes.
They replied and said that an 8 amp load is what triggers the fan. I applied an 8 amp load and got 5 volts at the connector. I removed the fan and is smells burned up. I'm waiting for their next response.
@@RayBuildsCoolStuff very nice. I hope all works out for you.
Hi Ray, sorry if this is a repeat question, but where are you buying your cells? Thanks!
Please subscribe and turn on notifications. I have a video I am preparing where I will explain the three suppliers I have used and my experiences with each. I will also do a cost analysis comparing cost to performance for the purchases I have made. I don't want to just give a short answer because it will be misleading and incomplete. I only want to share complete and accurate info backed up by testing whenever possible. I'm sorry that leads to delays.
it looks like 30 or 40mm fan..and you can thank God that it shut off..because if it is only small chip.those usually don't have any protection . I would suggest don't use the unit..buy new fan and change it and use it after that...
Btw did you solve the issue by using bigger washer so it would go over the small ridge..i would solve it by that .. if it is M8 screw..so i expect maybe M14 might be ok for that ?
did you replace the new fan and solve the problem ?
Yes and got a better quality fan but it was only about 5$ as I recall.
@@RayBuildsCoolStuff sorry for the inconvenience caused to you
I have over charged eve 230ah cells to 4.5 v and they have bulged badly can I save them and use or not
I would not.
Rd6024 Can it withstand 75vdc input voltage?
I would guess not but I have no knowledge of that.
what version of firmware is installed on your device , on my device is 1.36 , you can look the version on keys shift then menu(0) and 3 times arrow right - on riden6018 keys
you can update that with Pc software , i had some bugs on beginning with firmware 1.34 with wifi
V 1.36
@@RayBuildsCoolStuff :-( ohhh :-( ... not a fast repair :-( OR ...
hit it hard :-), then try again ... like hitting the controls in an old airplane
@@BavarianSuperGuy yeah, I’m pretty sure beating on electronics isn’t the same as beating on a carburetor float bowl or a starter solenoid. 😂😂
@@RayBuildsCoolStuff Ok .. a last try ... may the force be with you ... Hit It
@@BavarianSuperGuy 💪🙈🤬
How did you drill all them bus bars with out noticing they weren't made of copper 😆
I asked myself the same question. I think it was a way to stay humble and the root of that word is human which may be the real answer to the question.😀
@@RayBuildsCoolStuff they must’ve been hard going too. Great insight on crimping lugs in your other video, you saved me most likely having to redo a load of work, you’re a great addition to the community. 👌
@@MistaTerps Thank you so much. Best of luck on your project.
WHY DA HELL PEOPLE BUY THAT HORIBLE CHINESE PSU???? IT IS TRASH. BUY NORMAL BRND PSU..AT LEAST MEAN WELL
