Sorry for the ignorance, but shouldn't fuses be placed as near as possible to the source / battery?
The way you described, the circuit from the battery to the fuse is not protected , right?
@Nami ??
I'm about to buy BMSs for my long term living RV.
How can one trust this types of batteries for an RV??
One cannot afford to be hung without any power so easily!!
What have others done to prevent this??
Very interesting post!!
Thanks for sharing!
Please remember that what is in the spec sheet is 3 rods per side, which is ignored by most builders.
That will allow a much spread load...
Regards!
Thank you very much for your suggestions.
I ended buying the ANENG AN870 (due to cost considerations) and the UNI-T UT210E.
Again, thanks for your support
Setup:
- 24v
- 2 batteries (8x 280Ah)
- max consumption 160A (from both batteries)
Would you consider this 4 position rotary switch for your campervan?
(to be used as disconnect, or battery switcher, if maintenance needs arise)
I know that it's not the one in the forum documentation, but it...
The load seems to spread in a very narrow band of the largest battery side.
As the side wall is very thin, I wouldn't be very happy with this setup - but that's me...
Also EVE schematics show 3 rods each side for a reason... I would suspect load spread...
Hope the best for you, but would...
Regarding the fridge, I'm in the same boat as you.
I've decided for a 230v AC instead of a DC one.
Reasoning: the price difference will allow an extra one if this one goes bad, and extra funds for upgrading the electrical side.
Also if you look closely to both spec sheets (AC one and DC one)...
@FilterGuy , I understand that you've been doing a path from breakers to fuses... do you have any advice on this particular situation?
Reducing wire size and fuse due to real needs, even if equipments handle a lot more...
Thanks in advance!
Hi all.
I need some insights!
I'm building a system around a 24v 5000kVA Multiplus II - but this is applicable to any situation, I guess.
Instructions state to use a 400A fuse and 2x50mm2 cables (under 5 meters) to battery (LiFePo4 24v 280Ah , EVE LF280k based, with a JK 200A BMS)
Spec sheet...
Ahhhhh!I
(in a fixed fixture) I thought that if one cell makes (let's say) 100kgf after expansion in a single cell configuration, then 2 cells in the same type of fixture would produce 200kgf...
What you are saying is that 2, or n cells, will always produce 100kgf, right?
I'd love to read some...
I'm quite interested in your setup, how it's doing, and latitudes you're using it, as I'm buying stuff to do something similar.
I've got 1200w solar (though only 800w permanent as the third panel will be retractable), same(ish) battery size also at 24v, and a 5000w Multiplus II.
Main consumers...
If those are 2 12v batteries with 4 cells each, 230Ah, why not buy 8 extra 230Ah cells (easily available), and 2 BMS plus 2 boxes and 2 class T fuses and make 2 24v DIY batteries?
Basically you would end up with 2 quite similar batteries
Note: first evaluate very carefully the current...

Price:
248 USD, DDT DDP
Why call it cheap?
Compared to other solutions (EEL, Seplos, ...) it's around half the price
Edited: DDT should have been DDP
> we're looking to keep the cells from expanding
That may be you goal, but not what is specified in the EVE spec sheet for the tests - that can be found in this forum (sorry, I'm in the phone right now so can't easily make the search).
Hi Steve!
Would you consider this positioning for a battery box in a vehicle environment?
My thoughts are around heavy weight (cells), micro movement (expansion due to different SOC) and vibration destroying the silicone heating pad, with all the bad that could arise from that.
