Review on ⚡️ Renogy 20A On-Board Battery Charger for Flooded, Gel, AGM, and Lithium Batteries: Multi-stage Charging by Jeff Callier

I bought this to charge my new LiFePO4 DIY battery in my RV. I set it up so that the charger turns on when the truck's high beams come on. Wire tips are awkward to use, but they seem to stick to the wire very well. The good news is that it works and I saw 20 amps charging current through my Victron Battery Monitor. Two stars deducted for lack of support - a forum that Renogy doesn't respond to should complement a poorly translated written guide. The DIP switch configurations in the manual are ambiguous, and forum posts say that the LiFePO4 settings in the manual are wrong anyway. Renogy said they would post the correct settings, which they never did. Luckily someone posted it here. Why do I choose so much on DIP switch settings? LiFePO4 batteries are expensive and I don't want to guess what the charge settings should be! Correct the instructions and they can be successful. Victron just released a similar DC-DC charger, I wish I hadn't waited for them.
