Are guys keeping these on trickle charge/and "registering" w.o issue?
No issues. I have the VPH1200 and it lasts for at least 2 to 3 weeks. The smaller VPH900 started only lasting 2 weeks so I upgraded to the larger version as I don't drive the car much. I put mine on a charger every once and a while if I'm not using the car. However I don't leave it on a trickle charger indefinitely as I have seen that cause some issues on certain cars. The battery automatically turns off if the voltage gets too low. It keeps enough on reserve to start the car. However, on a car like the e92 you need to keep in mind that the trunk won't open without power. I have wired a remote switch into the cabin in order to work around this. Use the key to get in the driver's door, turn on the battery, start the car and you are good.
