  • High quality without the high price
I wanted to increase the capacity of my travel trailer batteries. My goal was to be able to use battery power for overnight pit stops and possibly a little boondocking. I came across Redodo Power and was impressed with their high quality and reasonable price. I purchased 2 batteries and built my system. My battery system consists of (2)100ah Redodo Power Self-Heating batteries, 600 watts of Renogy Solar Panels, a 40 amp Redodo Power MPPT Solar Controller, and a 1500 watt Fit4Less pure sine inverter. I also upgraded my travel trailer power converter to accommodate LiFePo4 batteries. I've used my system for 5 weeks over the past 5 months. Redodo Power has not disappointed me. They have plenty of power to meet my needs. The self heating works great and the BMS works flawlessly. I even discovered that they have built in Bluetooth. I downloaded and Android app and can monitor the batteries in real time. Well done Redodo Power! ... show more

  • Works well
It ends up floating at around 2 watts

  • Seems to be well made
The media could not be loaded. It's bigger than I thought which may help dissipate heat. Looks very beefy and sharp. Solid. So far it's working great. Would recommend this product, Fair price. Update: The controller started doing this lately after the sun goes down. Uploaded a video.

  • built well
the lugs at the bottom of the unit will handle two wires @10gauge and securely fasten. The unit has a good weight and the ratings are good for now.

  • Solid
Finally a decent controller from Amazon. Easy to read, program and connect from 75ft away with my phone. I'd recommend. Now to find a decent inverter here....

  • Great quality 40a mppt
I've been using this unit to power my 'solar workbench' now for the past month with just a little 200w solar panel and a 12v 100ah LifePO4 battery and it's been working great! The bluetooth connected up perfectly the first try, and everything pretty much squares up with the manual readings I get with my clamp meter. The build quality on this is even better than I expected, and I love the thick heatsink it has! This means they don't need to use a noisy fan to keep things cool and that's a big plus in my book considering the unit sits in my 'office/studio' where I want to keep things quiet. Super happy with this, as well as my 1000w Redodo inverter. ... show more

  • No back light
Charge controller and Bluetooth work well, the downside is that the screen offers no backlight, which is a bummer especially for the price.

  • Quality Controller
This is a quality controller that has a nice Bluetooth app. The app is very well designed and laid out. It’s very intuitive and not complicated. As for the device, it too is well laid out and the paperwork lists out the thresholds and limits for this device. Being able to go up to 600w on 12v & 1200w for 24v allows for many applications, especially for RVs. This is a great product. ... show more
