We just built our own battery bank on our sailboat (we liveaboard) using 180 amp hour, 3.6-volt CALB cells, and a DALY BMS, wiring the cells in a 4s2p orientation. So stoked on the upgrade! We charge our lithiums in 2 different ways. We send the power from our 120 amp Balmar alternator on our engine to our 100 amp-hour sealed lead-acid starter battery. From there a Renogy 60 amp DC-DC charger takes the load from the alternator and puts it in a lithium profile and in turn charges the lithium batteries. It was a fun build!

Very nice upgrade! Almost too good fit with all them cells, was it planned or was it pure luck? Wish I had that kind of space in my rig, working hard on finding a way to mount 8x100Ah cells for my 24V system. A couple of comments, hope you don't mind even if I (coming from a similar background) can clearly see you know your stuff very well. :) I would like to point out that while the orientation you use is probably ok, mounting that kind of LiFePO4 cell with the large side down is usually advised against by the manufacturer because of the distribution of the electrolyte. Also they should not be mounted with the safety valve facing downwards, for obvious reasons. Having done some work for one of the major Lead Acid stand-by battery manufacturers I would recommend you use a torque wrench for the battery terminal bolts instead of the ugga-dugga. Both because over-torquing and stripping the insert is a horrible experience, and because even a slightly too low clamping force you will make a surprisingly big difference at high current draw. With you using an induction cooktop and a 12V system, well you know... Finally, from bench testing my cells with the fuse mounted the same way you have (between two (blocks of) cells) I had a noticeable voltage drop across the fuse, leading to the BMS believing one of the cells was higher/lower on charge/discharge. This was with an 150A ANL fuse and only a couple of amps current. Have you checked that it won't throw off your cell balancing? Anyway, keep up the good work!

I'm curious how your batteries are working 7 months later. I just bought 16 271Ah 3.2v liFePo4 cells. I was going to hook them up similar to how you've done it with 4 cells in parallel for 1084Ah @ 3.2v then series them into 12v @ 1084Ah. The manufacturer, however, suggested that instead, I make 4 12v @ 271Ah packs and then parallel them into the 1084Ah. This is because with 4 12v packs each with their own BMS I can have better control over each individual 3.2v cell.

Very neat install. Love the expanding foam topper 👌🏼. Are you going to install a heating mat on this one? I’m also interested why you just use solar to charge the battery pack. I have a 200Ah Winston pack in my van and charge it from one large solar panel (circa 300W) and a DC-DC battery charger, which outputs just over 60A when the engine is running. It works well for me as we tend to only stay in one place for 2-3 days and the weather in Scotland 🏴 isn’t known for long periods of sunshine ☀️. Keep up the good work, love your videos.

@ARepublicIfYouCanKeepIt

Po-ta-to pa-ta-to, as they say. As Jason points out, 24V is optimal for a number of reasons, chief among them is simple math. A 4S configuration is needed for an adequate 12V output, while 7S suffices for 24V. Wiring, terminations, etc. are all smaller, less expensive and easier to work with than that which is required for lower voltage. Simply put: Watts (load) = Volts (charge) * Amps (current) So, a given load (W) at a higher voltage requires less current (A), allowing for smaller gauge wire, etc. For these reasons and more, I recommend 24V whenever possible. An added benefit of 24V is constant clean 12V output (via a buck converter) for all your 12V loads. They like this much more than the lower voltages that are possible when discharging below 3.0V (2.5V * 4S = 10V). While most equipment tolerate less than 12V, that pesky math comes into play again, resulting in higher heat from increased current (A) (100W/10V = 10A vs. 100W/12V = 8.3A). Some equipment is more sensitive and either won't run or risks damage if forced to operate. Most importantly, most 120Vac/12Vdc inverters have a low voltage cut-off that effectively limits the usable capacity of a battery pack when supporting AC loads.

LiFePo maintain voltage, going from 3.3 volts to a bit below 3 volts near the bottom. Seven is what you use for 18650 chemistries and 24 volts. But those chemistries have broad voltage swings. If I wanted to run a big inverter, I'd go with 24 volts, maybe 48 volts and just convert down some capacity to 12 volts. The video suggests they don't use so much power, just want to have a huge reserve. Not sure why they need 24v or higher. I really like the idea of harvesting the sun when it is around efficiently, but not using massive amounts of power.

Hi, thanks for the nice "Overlanders" + "Technik you need for the Trip" Channel . I was wondering how you monitor the upgraded Cells ( 20x ) now , as the Elektrodcus ist meant for 8s System max and you put the System in 12V ( 4x (5xSuperCells) ) . It looks from the Video that you are cabeling only every "SuperCells" and lack the Monitoring of the SingleCells . Did you experience Problems with that Config as you are not seeing the SingleCells ( Monitoring + Balancing ) any longer . Greetings to the Couple " aus dem Schwarzwald" ;)

There is no problem running cells in parallel, every electric car has done this for years. Also, our "cells" in fact have several cells paralleled inside already... The copper busbars ensure the cells are exactly the same. If any one cell starts to get weak, it will pull the others down with it and the BMS will report that. Then you'd need to single that one bad cell out. (But ours are still at 98% after 4 years of hard use)

What is that doing for your springs over time? That's a decent sized load to have on one spring. I think I'm going to split the load per spring. Do you notice one side sloughing because that spring seats faster? Does it change the amount of spring response (bounce) for each side when you're going down a back road or whatever? Loved the Great Stuff in a bag trick! Pure genius! :)

I've noted zero effect on our springs. The Lithium cells only weigh 5.6 kg each, the whole bank is 120 kg or 265 lbs - 50 lbs Lighter than me... Our chassis is rated at 17,500 lbs and we're currently at 13,890 lbs Our springs were custom built to carry 19,000 lbs - so we have tones of headroom.

The expanding foam on top was intended as a form fitting clamping fixture, not as thermal insulation. Our floor is a 3 inch thick composite panel much like the walls. With the batteries being housed inside our living space we found that the first 8 stayed at temperatures within spec without much extra effort.

@ARepublicIfYouCanKeepIt

While copper, or nickel-plated copper, would be optimal, aluminum suffices for this application. With some insight into Jason's psyche, we shouldn't be surprised to find matching buss bars at some point in the future. The cells are LiFePO4 (lithium iron phosphate) chemistry, prismatic cells. So named for their form factor. These cells are different from 18650 cells in that their nominal voltage is 3.2V vs. 3.7V. These cells have a charge voltage cut-off of 3.6V vs. 4.2V for 18650's. Discharge cut-off is the same at 2.5V. The particular cells Jason employed in this application have a capacity of 180Ah/576Wh (nominal). Additionally, LiFePO4 chemistry is known safety and long cycle life. To use these cells, or any LiFePO4 chemistry cells, be sure to purchase equipment (charge controller, etc.) that specifically supports this chemistry. Google "CALB prismatic" for purchase options. Jason purchased his, used, on Ebay for $150 per cell. That's $80 to $100 less than retail price for new cells. Hope this helps.

you are using 5 batteries in parallel for each "cell". Your BMS can not monitor that many cells individually (20 total), so what happens if 1 fails? fire?
@SweetLou0523
5 жыл бұрын
How that works is actually pretty uncomplicated: The bms sees each series string as one single cell as functionally that’s all it is. Once you series them, they charge and discharge at the same rate no different than if it was one single giant cell. The cells in series cannot go out of balance. Now, when you parallel those strings together, the bms then monitors the balance of each string to keep them in equilibrium. So, yes he started with 20 individual cells but as far as the finished product goes, once you series/parallel them there are only 5 cells total for the bms to monitor which is pretty standard faire for a bms to do.

Extracting electricity from diesel with a vehicle's alternator will cost $1 to $2 per kilowatt hour, $10 to $20 to charge our batteries... 2. At 50 amps would take 18 hours running the engine to charge completely. 3. The very low resistance of lithium batteries means you would need a dedicated DC to DC charge controller, otherwise the high current demand of these batteries would melt the alternator... I chose to run purely off of solar, in fact we often disconnect our alternators regulator connector and power the chassis electrical demands from our Solar and Lithium Bank. Getting about 15L/100km now...
