I am trying to get some data on what the power consumption of the JK-B2A8s20P-H (I didn't order the heating version, but apparently they gave it to me anyways heh). I plan to leave this connected to ~560 Ah batteries for extended periods of time, and I want to know how concerned I should be that this will drain the batteries. The batteries are for my RV which sits unattended, sometimes months at time. I apologize for all the questions, but after spending an hour googling I wasn't coming up with anything !
I did buy the LCD display, but also noted that it came with a push button switch (note on aliexpress says they just started shipping these as of 5/1/2022). What is the push button switch for? If that can be used to turn it on/off I just wasted 30 dollars on the LCD ? Good to know for others ... Can the push button switch power it completely off and on ? Also, what about the LCD display, I read from another post that it can only be used to turn it on -- not turn it off even with a long hold, which I find very odd. I used the LCD display to turn it on today, but that is about it. I imagine the push button could have done the same thing??
I read from another post that normal power consumption without the screen attached is 560 mW. That is kind of high, over a long period of time that will create a drain on my batteries, ~ 8 Ah per week which could add up, although I should be good for just a couple weeks at a time.
Ok, so if it is 560 mW, does that include the unit going into standby mode ? The aliexpress site (https://www.aliexpress.com/item/325...st.0.0.21d51802wjEkYf&gatewayAdapt=4itemAdapt) list the modes shown in the image at the bottom of the post. If the unit goes into standby, will it consume less. Also, will I need to do something to use it from there, it appears I will need to apply a charger to it ? That may not always be possible, so should I have the switch and/or LCD handy and connected to it should this happen? I did not see anywhere to configure the 1-30 days standby period listed in the image below.
