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

Let me start off by saying as an avid bowfisherman, we are very hard on our equipment.. I have had 7 or 8 over the years, upgrading and replacing. I have one hooked up to my work bench to Power my 12v audio system and a power port for working on electronics, and 2 in my pontoon for my 24v troller. Ive never really had any issues with the powermaxes themselves, especially for what Ive put them through on my boats lol.

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.

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.

Replaced my blown converter in my camper works amazingly

Im pleased with this product good power and decent price. Dont know the lifespan but hopefully years to come.

A lot of reviews mention how loud it is. Well, it is certainly louder than the original one. However, to replace the original one it would be at least double the price. We call that a push. Ease of install will vary depending on your rig. For mine I needed to get another piece of ground wire as the lug is in a different location the the original one. That said, if you think you will ever need to adjust the voltage be mindful on where those switches are when you install it. Otherwise, it works well.

Good item
