Good video, thanks. I think this type of system is a good balance between full DIY and full plug and play battery system. I saw another brand of these boxes where you assembled all of the components into the box yourself, this one was sort of cool in that it was pre assembled.
After internal shot-circuit and accumulating of H2. C2H2, CH4, C2H6 gases inside and ignition and chain reaction of all 8 cells in the raw, what will owner have to do to prevent such events ? How BMS can prevent internal short-circuit or accumulation of gases and thermal runaway ? Such explosion can destroy house.
I would think you could easily add a circuit breaker. I would add one and perhaps a class T fuse, but I am a belt and suspenders type. Good review BTW. I have never had a cell bloat in 5 years, but I am of course very careful to USE A BMS! Provided you keep the cells in the operating range (2.5v to 3.65v) you should get only very minor bulging, not bloating.
Excellent, clear explanation all the way through. One thought: The front cell-box retention plate could be fitted with longer bolts, compression springs, and appropriately sized washers to apply a fairly constant retention force on the cell stacks while allowing movement for thermal cycling.
At the end, you have the case on its side. Would it be safe to leave them that way? I am figuring the best non-rack mount for a new power house and 6-8 on their side, space wise makes sense in my mind for a few reasons. Nice build and seems complete. I agree about wishing it had a breaker. Final decisions really comes down to the BMS. Curious for an update on the BMS and/or performance.
@@LithiumSolar Thanks. Doesn't absorption within the BMS help with balancing though. Would be nice to know what that BMS is, I am looking at these racks at present and am a PACE BMS fan.
I haven't bought one but the Alibaba site is quoting me $442 USD for 230 Ah kit version (no cells of course) and shipping of Seller's Shipping Method 3 (Ocean) | MULTIMODAL_TRANSPORT 35-45 daysShipping Time $132.70 USD Estimated Cost
No, it's not necessary that it be built in to the case. You can add one externally if you'd like and should be wiring it in compliance with local electrical codes and common safety procedures.
The back side of this battery housing appears to have openings which would allows for expansion in the belly area of each cell. So the front side (full) compression plate would serve no purpose. So in my professional opinion, if your goal is to prolong the life of your cells, I would avoid the purchase of this battery box and buy a box that provides for full cell compression.
While you pointed out an interesting thing here, an aluminum-cased cell is not going to push out a hole like that... Sure, you might get an extra millimeter or two of expansion vs a solid back, but I think it's negligible. Also, the idea is not compression... it's just holding the cells in place.
@@LithiumSolar Several years ago, I built a frame similar to this battery box design, where only the edges where encased by approximately 1". After 6 months of consistent cycling, I found that the cells expanded by approximately 4mm to 5mm at the center point of the both cells at the ends of the frame.
@@graypistachio4141 No. the epoxy board is flexible and will not prevent bulging, only a steel or aluminum 2 - 4 mm plate or much thicker HDPE plate tightened to approximately 2.5 Nm will prevent bulging.
@@LithiumSolar you did not really try it out. i did not mean whether it is balancing or not. what i think is important whether or not the BMS is capable of balancing dells. some of the balancers can't do it, unless the cells are brand new and already balanced before built in.
@@ursodermatt8809 I see what you're getting at. I don't have an exact specification for this BMS, but they're typically 30-60mA. That is more than capable of keeping a 230Ah battery in balance. The instructions specifically state that you should have them balanced prior to assembly. This is true for practically every single battery, not just this particular case. If you have a cell that's self-discharging faster than the others, and so fast that the BMS cannot keep up, then that cell is faulty and should be replaced. Again, this is true with pretty much any battery out there.
@@LithiumSolar so, personally, i would not trust that balancer. that might work when the cells are brandnew but a few years down the road ....... and also notice when the battery can't be balanced for a few weeks because of cloudy weather, i don't think the 30-60mA will cut it.
@@ursodermatt8809 This is one of the better brands of balancers out there. Quite honestly, it sounds like you have a turd and are blaming the balancer for your turd not being balanced. The 30-60mA is pretty standard, and for good reason.
No, it's not necessary that it be built in to the case. You can add one externally if you'd like and should be wiring it in compliance with local electrical codes and common safety procedures.

I built the same kit from a different company 230Ah. I lifted it from the ground to the back of my truck and back off again. Yes, It is very heavy!
Which brand did you get? This is in my basement and there's no way in heck I'm getting that up the stairs. Going to have to disassemble to move it.
@@LithiumSolar Seplos was the brand. Very similar but they had neoprene foam in between the cells and not the resin board which I prefer.
Do you have a link?

I have a seplos 304AH kit, and wheel it around on a cheap furniture dolly. Works fine.

Enjoyed the video. Thanks for sharing
Thank you for sharing your knowledge. A helpful and great video.
Good comprehensive video. Thanks!
Wow 18650store has really lowered their prices. I paid $140 per for 280 ah cells a year ago. Now the 304s are $90.
There is an oversupply in China of LPF cells. Prices have gone down 50% in some cases.
@@akhurash Is there a supplier with a lower price than 18650 store?
ALIBABA, WANT 1200$ SHIPPING FOR ONE KIT. CRAZY !!!
That's ridiculous... Are you shipping to the US? Did you ask them for a quote and that price is what they gave you?
@@LithiumSolar I WENT THROUGH THE NORMAL CHECKOUT AND THAT WHAT IT CAME UP TO TARPON SPRINGS FLORIDA.
Wtf☠️
I bought thru BasenGreen website. Including shipping to CA, it worked out to 12.3 cents per Wh which is really great.
@@ClassicKartsNZhow did you get them to ship to NZ? They told me they can't ship here!
You got me thinking. Thumbs up 👍
Is it compatible with Victron inverter/chargers?
Just ordered one of this kts, with batteries included 1800 dlls...
Excellent, clear explanation all the way through. One thought: The front cell-box retention plate could be fitted with longer bolts, compression springs, and appropriately sized washers to apply a fairly constant retention force on the cell stacks while allowing movement for thermal cycling.
The Full_Batt_Cap setting is still 230Ah. You have to adjust that to 300Ah
This is a 230Ah battery, curious why you would recommend setting it to 300Ah? Is that just a starting point before it calibrates?
@@LithiumSolar Sorry, I thought you said it was a 300Ah battery
@@lecramred4453 Oh no, sorry. They do have a bigger version for the 280/310Ah cells though!
@@LithiumSolar Yes, I have 5 of those

No, I would definitely not use it in any orientation other than flat. I just stood it on the side for videoing.
Thanks for the info on this one. Does this BMS ( not sure of model ) have Absorbtion and Float settings ? Most don't but it's crucial imho.
Absorption and float are charge settings, those would be programmed in your charge controller, not the BMS.
@@LithiumSolar
Thanks. Doesn't absorption within the BMS help with balancing though. Would be nice to know what that BMS is, I am looking at these racks at present and am a PACE BMS fan.
Is it possible to have a 24v version of this battery built into this case??
You could wire the battery for 24V if you wanted, but you would not be able to use the included BMS and you would need to make some custom wiring.
If you have multiple batteries how to tell them which one is second, third etcetera?
Nice! DIY rules! thanks!
Looks good and thanks for the full explanation! Would it be possible to use this Basen Green battery box with the portable hand truck battery system??
Can the box be placed vertically?
The manufacturer does not define acceptable orientations. Personally, I would not place it any orientation other than flat as it's designed.
Can I connect 5 of these in parallel?
I don't see why not... provided you're using properly-rated cabling and fusing.
had any problems with windows drivers? I don't seem to be able to make it work on win 11
I am in the market for a 24v 300ah lifepo4 battery actually I need 2. Do you have a favorite? I’m looking to spend around 1500 per battery. Thank you.
I have bigbattery 24V GRILA, 36 Months old working perfect. If you r in north texas. I will sell it for 800

BMS is very close to a JBD.
I don't think it looks anything like a JBD. Is there a particular model/version you're thinking of that I can check?
