Easy to install. Pay attention to wiring because wire color isn't standard. Instructions explained. Had to slightly modify mounts for my applicatio.

Exact replacement for my RV. Easy to hook up. Had it in for a while and no problems at all. The regulator I replace quit charging my batteries. This fixed the problem. Affordable pricing as well. Fits many different units as well.

I have purchased this product twice and both times I have got one of the batteries that won’t charge

This works well at a good price, there are a couple of minor things that could be improved but cost is definitely a huge factor for why I still gave it 5 stars. Functionality-wise it works awesome. It cranks out just about the full 55 amps at a full charge state, and lowers as the batteries reach full, eventually reducing to a maintainer. The directions are written in poor English and difficult to understand. The wiring colors are off, so make sure you actually reference the poorly written manual so you know what color is your hot, neutral, etc. The housing is also flimsy and leaves high voltage components exposed, you will want to make sure you get something to protect this. I use it to charge the batteries on my bus conversion RV when plugged into AC power, it is perfect for my needs. I definitely would recommend this product.

I have tested the output of this charger with five LiFePo4 batteries in parallel. The charger pumps out 700W which is close enough to the advertised 55A. I have not run all the conceivable tests yet, like how well it trickle charges, or the full charge sensor, etc. but I did test it with high voltage (at 15V) and the charger did not turn on. When connecting the charger to the batteries, there is a spark, most likely caused by a capacitor draw. However, the standby power draw is negligible (it did not register anything using a Victron shunt). It would have been nice if the charger had a cheap cover, but it is what it is... The AC wire colors are not up to the US standard (positive is white instead of black and vice versa). The included user manual is readable but is not great. Overall, it's a usable battery charger.

It only has a few wires to install and each one of them are labeled to prevent confusion. Has holes in the bottom plate for mounting super quiet and performs flawlessly!

This is a neat replacement that fit right in, the easy fit made installing this super straight forward, like half a hour of work. Inspecting the board before installing it, it seems well made, connections are well secured and this doesn't feel like it will cause issues. After installation, it's working well and seems to be providing good power. The fan seems to kick in more than the replaced unit's did, but it's quiet enough that's not too annoying. If you need to replace this part, this seems like a solid option.
