How to choose the right model for your damaged converter?

Models of power converters are WF-8955-MB, WF-8955-AD-MBA, WF-8955LIS-MBA.

WF-8955-MB is used for lead-acid batteries, WF-8955LIS-MBA is used for lithium batteries, and WF-8955-AD-MBA can be used for both lead-acid and lithium batteries.

So if your original converter model is WF-8955-MBA or WF-8955-AD-MBA and the battery is lead-acid, you should choose the lead-acid version.

If your battery is lithium, select the lithium version.

How to choose the right brand?

The voltage of the lead-acid battery is 13.6V, the voltage of the lithium battery is 14.6V, and the curve of different types of batteries is different when charging.

Other brands only design one type of converter to match lead-acid batteries and lithium batteries. This means that it doesn't fit into your battery and can only provide a simple charging solution.

Our converters differentiate between lead-acid battery versions and lithium battery versions. Whether your battery is lead-acid or lithium, you can get the right voltage and charging process. This design has the same voltage and charge curve as your original converter, which will greatly extend battery life and increase usage time.

Three stages of intelligent charging

Increase your lead-acid battery voltage to 14.6V, then enter trickle mode and maintain battery power.

I upgraded the house batteries in my RV to 410Ah of Lifepo4 batteries. The original "auto detect" converter wouldn't recognize or charge at the higher rate that the lithium batteries need, so I replaced it with this unit. The ad says it has a silent fan and that couldn't be further from the truth. The fan sounds like a jet about to take off. I am thinking about replacing the fan with a quieter one or with two actual quiet fans, one on each side of the converter to help with air flow and cooling and eliminating the loud fan that comes attached to this unit. Again, this unit does a great job of charging the batteries. My biggest and only complaint about it is the noise level of the fan. If you have any "light sleepers" in the RV while using this unit their sleep is most likely to be negatively effected by this unit.

This was a perfect fit for upgrading from our lead batteries to lithium! Easy to install because of the exact fit!

I had high hopes for this inverter. It was working fine. Then, as of yesterday it just stopped working. My camper was dead. I had to plug it in and now luckily I have solar because it won't work. Thank goodness for Amazon coming through with a refund...

I installed this board in June and everything seemed to work other than being very noisy.They claimed it was very quiet but it was not. We took a trip in July and after four days the batteries went dead even though we were hooked up to electric. I charged the batteries using a 10amp lithium charger and the batteries came back to about full charge.I finally had a chance to check the inverter and found that it was not charging the batteries. I then replaced it with the original inverter and it worked but I needed an inverter to charge my lithium batteries so I am asking for a replacementI still have not received a replacementStill waiting for a replacement or my money refund

Changed this converter out to handle lifepo4 batteries I installed on travel trailer - surprised how much faster they charge my lithium battery.

The cooling fans runs much more than the orginal unit. It is rated as 53amps, I normally get 25 amps.
