I just met someone who purchased several months ago the following batteries
(see link - maybe not this supplier though) - They were USD $1700 inc delivery
for 1120ah 12v (16 x 280ah @ 3.2v)
Has anyone used these or have any longer term usage stats on them as they seem incredibly cheap
He was very happy with them still and even runs his hot water
system off them and his only charge source for them is 1.5KW of solar
. He showed me the BMS (he installed his own, the batteries
do not come with them) via Bluetooth and they were all pretty much sitting equal still.
