Powermax PM3-55LK 55 Amp 12 Volt Power Supply (Replacement for WFCO WF-9855) Battery Charger with 3 Stage Smart Charging Mode, Built-in Cooling Fan and LED Indicator Light, Lithium Compatible

My new batteties would do a nose dive with the old converter! This was properly set for voltage and charge rate and it does the job. very easy install. Excellent get one>

This unit works fine but is very noisy. Too late to send back, but I would iff I could. It will keep you awake at night when it turns on.

Works good, kind of noisy under high load while charging nearly dead deep cycle batteries.

Just got yesterday a week ahead of when they said and I hook up today works looks great

I was able to adjust the voltage level up so that the unit will pump close to rated load into the house batteries during bulk charge phase. The original 55A converter would only pump out 10-20 amps during bulk charge due to the low upper voltage limit and the fact the unit is located over 20 feet away from the house batteries and Fleetwood only ran 6 AWG wire to the unit. The small wire causes big voltage drops at the battery with currents over 15-20 amps. This unit allowed me to adjust for that. Also has a manual mode that allowed me to bump the voltage way up for several hourse to due a true reconditioning on the house batteries. Have to use carefully to avoid overcharging and boiling off the batteries.

Replaced my blown converter in my camper works amazingly

I use this unit as a solar charger for a backup system. It installs easily and it has a very high build quality. Since it is being used for a back up it will probably not get a lot of use, However I expected it to behave flawlessly when I need it to.

I installed this in a travel trailer, plugged in to a 120 Volt outlet. Used 4 of 6 gauge wire to connect directly to LiFePo4 battery. Although none of these converters output power as they are rated, this PM3-55LK put out 45+Amps. It immediately output almost 700 W until the battery was 98% charged. The voltage increased to 14.6 V As the average decreased to very low. Then continued to power my 12 V appliances without discharging the battery. This device worked perfectly for me.

Out of the box, set at 14.77v, yiur results may vary, but mine was ready to go.

Good item
