Are there other recommendations? There has been several threads on 1 battery vs 2, etc. Best trickle chargers for the single lithium in a M8, but I'm pretty confident my 2020 M850i has two batteries, i.e., AGM and Lithium. Any recommendations beyond the BMW charger? |
I use this to charge and maintain the battery of my 2022 M850i while she is in storage for the summer in Florida. Works great. I suspect it's the same as the re-labled BMW version at half the money.
