So the west “stole” the invention of black powder and guns from China lolJebao pumps are not great if you want to use and coordinate more than 2 in alternating mode.
Battery back up - any dc pump can be easily and cheaply pluged into a diy battery solution customised to your needs. BOM: 1 relay, batteries of your choice, dc connectors matching pump's, battery tender, wire.
As for reliability ... buy 1 from multiple stores to get different batches. I have 5 for almost 1year. 1 died so far. @~55eur per powerhead I'm fine with that.
I bought 2 10000l/h DC return pumps (adjustable in 1% steps) for 200eur. 1 in tank running 24/7 (just need to clean every couple of months), the other is backup/water change.
Say what you want but jebao is good value - especially for a nano where 1-2 small jebaos would be plenty.
As for "stealing technology" .. its a pump ... its a microcontroller controlled pump. There is nothing really that innovative about it. Just more robust to handle saltwater - Otherwise it would be a completely generic product.
Now fancy controllers that drive the pumps will have proprietary software .. but jebao does not steal that.
the only innovative pump that jebao 'stole' is gyre ... and to be honest the only innovative thing about it is to make impeller bigger.
) ... and I would like to run it lower but 10% does not move water at all... ****** controller with limited power settings, jebao has 1% steps why not Maxspec? They have a true 3 phase brushless motors + the rotary encoder on the controller is an abomination)
