Q

good morning, the password 123456 is not working to configure, what should I do?

by Eder, on 29 June 2024
A

There are 2 passwords. One to connect to bms with Bluetooth and one whenever you want to change settings. The Bluetooth password is 1234 and the password to change settings is 123456

Good morning This Bms can be used for lifepo*****s 100A batteries?

Yes it can. But 20p does not mean 200amp.

The two products arrived damaged. The outer wrapping film was fine, but both cardboard boxes were damaged. The retaining tabs are bended as you can see in the photos. And one PCB seems to be damaged too. The second point: The headers for the RS485 is missing. In the descxription and on every photo you can see the header for RS485 interface. why is it not soldered. The last and most annoing point: there is no response since two days for my complain. That is a really bad service. Should I really buy here again?

Came well before the official date! Nice packing, no damage. Batteries have not yet arrived so cannot test it. But looks nice.

I received the JK bms with complete wiring without an on/off switch as the seller stated in a short period of time._8s2A with can heater _Although I haven't tried it yet, I am very satisfied because it is the second one I purchased and the first one has been working flawlessly for two years with EVE 280K.
