Solar charging a LiFePO4 Battery #2

[smithjones]

You’re on the right track overall. For a 12V LiFePO4 like this, you mainly need a controller that supports LiFePO4 profiles and lets you set the charge voltage around 14.4–14.6V with a current limit under 6.6A. Battery capacity itself isn’t an issue, it just affects how long charging takes.
A small MPPT controller with adjustable settings would be the safest choice, especially if you later change or upgrade solar panels. Just avoid generic lead-acid only controllers, since they don’t handle LiFePO4 well. Your assumptions about series cells and charge behavior are mostly reasonable without opening the pack.

Hello,

No, the origenal thread is here:

I moved the necropost from that thread.
The thread was 6 years old.
