Like everyone else, i need the password to access the settings on my new battery. Im actually really upset there is no information included for this. Im beginning to see that the saying “you get what you pay for” applies for lifepo4 batteries as well. This is ridiculous
Like everyone else here I need the app default password. Not sure why it would not be included in the app instructions.
Please send me 1) The password to the IOS “BMS Meta” app so I can set my own PW and 2) how do I change the temperature display from Celsius to Fahrenheit?
Thanks
Great packaging on the 12V/100Ah Mini!
Please send me 1) The password to the IOS “BMS Meta” app, 2) PDF versions of the manuals for BT and the Owners manual for the 12V 100Ah Mini. Thanks!
I just bought 8 each 12v 100ah batteries. I plan to use them in 4S2P configuration.
When I bring up the Bluetooth APP, I am seeing 8 individual batteries.
Is there a way to see all 8 batteries at the same time?? Having to switch from one battery to the next is rather time consuming.
I also need the password to check and possibly modify the BMS settings.
Can you please provide me with the password to modify my batteries settings!
Hello,
I installed the BMS Meta for iPhone and I can see the battery status.
I would like to set parameters in the BMS Meta app , but it is asking for a password.
What password should I use ?
Thank you!
