They have a coolant loop. But I've done the math and there's no way I can pull enough to require it. 12000 watts surge / 48 volts is 250 amps. 250 / 12 banks of cells is 20.8 amps. Even if I was to loose 1/2 the packs and was running on the remaining it would only be about 42 amps from each bank of cells. That's less then 0.2C so unlikely to cause any heating in the cells. It's even less for chargingDo those batteries have liquid cooling? Don't think you will pull on them hard enough to need it, but might be worth hooking up the cooling loop just in case you ever pull on them hard with inverters powering something like AC or the house during a storm if needed.
