solar snapshot, battery costs

solar data I wrote this elsewhere but thought I’d share it here: As of 10:59am local time, the panels have made 790Wh today (244.72w at the moment. It should level off as charging current decreases and I shut down the laptop for the day. By 11:25a when I am writing this blog post the panels

backchannel: AGM @ 80% depth of discharge

I’ve seen similar claims before, but I haven’t done the homework until I was inspired by this one: >they are design such that you can use more of it without damaging the battery’s lifespan. So comparatively, AGM compared to FLA batteries with the same rated capacity (the same amount of lead in them) will have
