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

Very happy with this purchase fixed my issues with my rv

Returned

This converter replaced the blown one in our camper perfectly. Only thing necessary to use it was to add an outlet to plug it in which was way less expensive than buying the original replacement part. And in doing so we didnt alter it so as to void the warranty. We have been using it for weeks now with no problem at all...very happy with this unit. I forgot to take a photo after my husband installed it or Id share his handiwork.

Seems to work well

Good item

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

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.

Fast shipping, easy to install

Great value
