Only 0.5C discharge.hmm, thats a good question, somewhat low maximum charge current rating (0.5c), that's the only thing that stands out in the specs to me.
Looks like it is a Ozzie product that is not available in the USA.so nothing is screaming sus to you guys? maybe just good shipping rates to AUS
So I am going to say that they are NOT cheap ... right now many of us are getting (4) 3.2V 200aH batteries (with bus bars) delivered (to the US) for $426
so nothing is screaming sus to you guys?
True, the DIY route is still cheaper. BUT, they are cheap in the in the sense that they are significantly cheaper than any other prebuilt batteries of the same capacity that I have seen, which should make you if not suspicious at least inquisitive.
You've totally lost me ... I think its the other way around ... the 200aH batteries that I get for 426 I KNOW exactly what they are - I also put exactly the BMS I want -- and use the cabling I want ... A majority of these ready-built batteries have a cheap BMS and the wrong cabling in it ... also the pre-built batteries are coming from the exact same place that most of us get our batteries from -- so why are you paying someone $400 just to drop it in a box and slap a label on it ??

Suspicious might be too strong a word, but I would definitely want to do some due diligence before purchasing, and get some idea why/how they undersell the market.
As ghostwriter correctly noted, a similar capacity battery can be built somewhat easily for less $$, with the added benefit of knowing the quality of the components used. But this is not everyone's cup of tea and is outside some peoples comfort zone.

and 4 in parallel gives 400A max discharge and 200A charge.. so a reasonable configYes they CAN be run in parallel, A mate has been using these in his coffee van for over 3 years Perfect, I because of him got 4 200ah, all running Parallel Perfect no issues, Charge quickly never let me down Referring to these Volta https://www.ebay.com.au/itm/15-OFF-...399732?hash=item1cdf0f33b4:g:Qb0AAOSw1y1d6kCw
They have just released some upgraded units, discharge rates of 1C now on the 100Ah unit - with a special price of $404AUD. Only rated for 1500 cycles, which indicates to me there is a quality difference between these and their previous units - but 1500, at 100%DoD should still last a lifetime in my van.To be clear on their pricing vrs raw LiFEPO4 cells. At AUD$1300 for a 300AH 12V unit thats $1.08 per raw AH 3.2V cell.
DIY are available for AUD$110 for 280AH cells Lishen (from Basen) plus shipping. Shipping is approx $35/cell currently to AUS.
Without shipping DIY is $0.39 /AH but with shipping approx $0.52 c/AH . So just under 1/2 the price , but add BMS and packing and the Voltax units (with 3 yr warranty from local suppliers) is a reasonable deal. BUT their limited to 1/2C discharge and 1/4C charging (probably due to choice of BMS) so that can be limiting for some. With an electrodacus BMS in a 24V config, DIY BMS costs are approx AUD$300 with some extra bits. So that brings a a comparable 280AH DIY with Electrodacus + shipping to AUD$1460 vrs $2600 for 2 x 12V Voltax 300AH units.
