Thanks. This looks like a good choice for me. Happy to spend money on quality.
400W @12V would be ~33A at the battery side, assuming no losses. So more than 25A charging capacity might be a good idea.
Renogy lithium batteries claim a max charge current of 100A. Seems insane.
This video was helpful. The BCDC “classic” is sealed, which I want. So is the BCDC Alpha. Alpha may be the answer for me since it’s smaller, has nice terminals, and is roughly the same price.
Anyone here have experience with an Alpha?
