$20 AUD pickup from Belrose 2085 Can ship AU wide +$12 or internationally 1 x fuse holder 1 x 100A fuse 2 x 60A fuses 3 x 80A fuses 3 x 150A fuses

I have 3 fuse holders & 4 x 400A class T fuses (PN: JJN400) 1 fuse holder & 2 fuses have never been used, the other 2 holders & 2 fuses have been used but are in perfect condition. Located in Australia, but can post internationally no issues. Each Fuse: $60AUD / $40USD Each Holder: $80AUD /...

So whats a solution... As the BMS is no longer balancing, you could increase the impedance of all the wires by inserting resistors to EVERY wire. This would force the Balancer to draw from the cells & not the BMS internals. Add some capacitors in parallel with the cells, hopefully they would be...

OK - think I figured out whats happening... Here's my diagram as to why HIGH voltage cells are causing neighbouring cells to read HIGHER. Of course its most likely that its the balance cables and the BMS (NOT the balancer) Internals that are getting pulled high & low, due to the impedance of...

100% get that - & when you're charging a cell through a balancer - i'll read high, perfect. What i'm seeing is that when cells are being DRAINED by the balancer, the voltage is reading HIGH on that cell (or its neighbour?). Have a look at the middle balancing picture... 15 is low... BUT! 14 &...

I appreciate your feedback. I am after the WHY - a deeper understanding as to exactly why it is happening, to work on a feasible solution. Reducing the balance current is a really, really bad solution. You install a balancer for a reason, reducing its ability to be a balancer goes directly...

No - that's what i'm seeing too, whacky when balancing! Maybe we put a heap of capacitors across all the cells to smooth it out lol

Agree with with low voltages... but... I'm seeing HIGH voltages on Cells that its pulling from... the high voltage cells are too high... the only thing the NEEY is doing is pulling from those - so why are they above the normal voltages. Is the correction factor causing an increase in voltage?

Here's the setup... 2 x 16S LiFePO4 bank All balancing cables come to a junction block From that block I have both the JKBMS, & NEEY active balancer The voltages in the NEEY are spot on, consistent and correct (as per multimeter) The voltage readings on the JKBMS are jumping around a LOT, by...

Revive an oldie.... been thinking about this myself... I cant find much from inverter manufacturers on the benefits & why... BUT there *could* be many, many benefits - but they come with a risk, its all software, so is the programmer going to make a good decision for you...

SolarAssistant.io - simply superb software!!!

FYI - Install manual has the details... Shows Aus/NZ vs others On the Synsynk p27: https://sunsynk.com.au/wp-content/uploads/2022/05/3.6kW-5kW-Installer-Manual-v14-Australia-FINAL.pdf

Plans are free & on thingiverse above :)

Broke out into a focus group, re-imagined the design then shifted a few paradigms... New design - now features ribs which clip onto the 20mm bus bars, holding the caps secure in place. In the old design they just sat on top & could be bumped off etc. They also allow side access to the bar for...

Trying to figure it out - but looks like the configured capacity is an input factor too, i've had a few full cycles and i'm still seeing crazy capacity jumps. I've got 2 packs in parallel, I didnt fully test the new pack for capacity - so took the manufacturers word (304Ah) for it & it looks to...
