## Customer Reviews

### ⭐⭐⭐⭐⭐ Don’t be fooled by the affordable price, great quality!
*by J***R on June 20, 2025*

I have a mix of two lithium batteries wired in series to my trolling motor and a lead acid cranking battery. I needed a new 3 bank charger that could support LiFePO4 lithium batteries and a lead battery independently.The first time I charged the batteries with this charger I got a little nervous because I left them connected long after the charge was complete and the LEDs on the charger were red. Later I realized the cause was a breaker was reset in the electrical panel. The power disruption caused the red LEDs ( my boat fully charged and the batteries and charger were fine).Since then I moved the charging cord to a clean circuit to avoid power disruptions and no more issues — a fully charged battery always produces green LEDs.I don’t know if this is a problem, but it seems strange that when I remove power from the charger after the batteries are completely charged, the bank responsible for charging my lead acid cranking battery doesn’t turn off. It seems like the battery is back feeding power to that bank at least enough to keep the green LEDs lit for days.The quality of the charger has been great after about 15 charges.

### ⭐⭐⭐⭐⭐ Well built, charges quickly
*by T***L on June 9, 2025*

This is a great charger. It charges fast, the connections are really well made. Everything is solid and sturdy. Would definitely recommend.

### ⭐⭐⭐⭐⭐ Soarfly battery charger
*by E***L on May 30, 2025*

I have the charger attached to two LifePo lithium batteries in my boat. It has been great up to this point!
