Great Battery Charger

I bought this charger/converter to charge the lifepo4 battery on my off grid system. I needed a fairly robust charger for my 325ah battery and i had to be able to adjust the output to the proper voltage. I only have to use it if we have no sun for 3 days and have only used it once since i received it 2 weeks ago. This charger performed well and replaced the 2. 2 kw needed to refill the battery in about 3. 5 hours, which is right in line with the specs of the charger. Be advised whenever charging a lifepo4 battery do not leave it unattended. This charger is not specifically made to charge this type of battery; if you know

the specific settings for your battery and make the adjustments this works great and costs about a quarter of what a charger that is made specifically for these types of batteries.

Excellent product

I installed in a rather restricted place, but made ducts for the intake and exhaust. The converter is well-made, quiet, and doing an excellent job.
