I wonder if something like https://vi.aliexpress.com/item/1005004622768370.html or https://vi.aliexpress.com/item/1005006129467622.html would work both 48v, single unit, bms included. the only question would be if they are ip rated at all (which I can't find info on). they only seem to offer 50A sustained output though

that's awesome, thanks mate!

that's fantastic, thanks for sharing! did you happen to grab photos of the the new layout?

heh, just get https://www.bigw.com.au/product/voltx-48v-100ah-pro-lithium-battery-lifepo4-100a-bms-deep-cycle-rv-camping/p/9900111907 and then use 5% off vouchers and your rewards 10% off for the month on that, save a fair whack of change! I also found https://www.solarbatterywarehouse.com.au/solar-battery-shop/fusion-solar-agm-batteries-6v-5lang-bc89t-6c2c2-sswn5 for a bit cheaper, so there's other options out there if you want to go a single big unit. or https://au.renogy.com/core-12v-24v-48v-100ah-deep-cycle-lithium-iron-phosphate-battery/#op={"id"%3A509%2C"options"%3A[{"optionId"%3A"252"%2C"value"%3A"485"}]} for something that might be drop in for an even cheaper price

spoke to litime and they don't have the 48v batteries in au, with no short term plans to sell them

in au the relion are being replaced with allion, at least according my local RJ batteries shop I am keen to look at the litime, but finding a local 48v is proving a bit hard. 12v at 50ah can be picked up on eBay for well under $300 each though

another aussie with an e1 looking to change the batteries! this thread is tops, so thanks to everyone who's shared details looks like litime will be decent and reasonably easy to get (ebay or direct from them). the relion are only available at rj batteries, and they don't publish prices online which is pretty crappy also I posted about my experience a few years ago if anyone is interested -
