I am replacing my AGM batteries on my 2015 Winnebago Itasca Solei With Lithium. I first upgraded my Magnum controller with a new one (Simple plug and play) and had a lithium selection automatically. I changed out the batteries after doing the initial charge and equalization routine. The bluetooth information on the Renogy app is amazing. After adding the Renegy One Core I had all of the info in one screen system. I previously used Battle Born but had a Renogy Inverter that worked well on my previous Thor rig. I picked up 4 Batteries on Sale for a little more than half the price of the Battle Born. These should last my lifetime with this rig. I have added the 50 amp dc-dc/solar charger and it is online and working. It seems to intermittently charge the chassis batteries and is maintaining 12.7 volts. The hard part was replacing the house battery to chassis battery relay. Battle Born makes a lithium programmed replacement so the freightliner alternator does not overload. The contacts on the LI-Bim 225 are narrower than the original and I had to remove the whole thing and move the house, chassis and fuse mounts to accommodate the new relay. The only reason to have that with the charger in line would be if I needed to boost the chassis batteries. Given what I am seeing with the Renogy Charger I doubt all that trouble is necessary. I have wired the rig to the roof with solar cables and a junction box and will wait until I can catch the solar panels on sale. Given my use of the rig (I am full time in it) I will likely just use the Magnum inverter-charger for the Lithiums. They have so much more capacity than the AGM's. The magnum charger can deliver 200 amps and quickly charges the Lithiums. If you are on a 15 amp adapter you have to throttle the charger to 30 percent or you will throw a 20 amp breaker quickly. I am pleased with the install. Shipping was quick and easy and online documentation has been more than enough for my install. I will be anxious to see Renogy make a shunt to accurately measure output amps of the batteries for the Renogy One. Battle Born has one already that works great. I will not use more than 600w of solar so the combo charger will be just what I need.

I recently purchased two of these for our RV to upgrade our lead acid batteries. Going into our fourth season, we were on our second set. Two issues: The lead acid batteries never reach a maximum sustained charge after about six cycles. They deplete. Second, they quickly drop below fifty percent capacity, further degrading their maximum charge capacity. I even trickle-charged them over the winter and topped off their fluid. Needless to say, it was getting expensive to replace batteries every two years. I wanted to have LiOP batteries installed by the RV dealer, but most salesmen don't know anything about RV electrical systems and only sell flooded unsealed lead acid batteries. I've been watching prices over the past two years, hoping they would begin to drop with EV sales growth. In some ways, I'm glad I waited. These new batteries from Renogy are not only a remarkably good price in comparison to other brands, and I've looked at all of them, but they offer a waterproof, fire retardant case and automated battery heater. I topped them off, balanced them, and just installed them this weekend in our RV. They are strong batteries. Running them overnight with no shore power, our fridge, lights, and heater on, they only dropped to 99%. By noon the next day, our 200W solar panel topped them off at 100%. They charge extremely fast from our solar system compared to our lead-acid batteries, showing their design efficiency. I am more than impressed. My hats off to Renogy for coming out with this Smart Pro battery at such a great price. I cannot recommend them enough.

These lithium batteries are built to last and offer reliable performance. I can trust them to power my devices consistently.

Working great so far. We"ll see what happens in a few months. So far it"s great I enjoy the Bluetooth feature

I'm impressed by the excellent battery life of these lithium batteries. They last a long time, providing extended usage.

I recently purchased a trailer and wanted a battery more powerful than the old lead acid batteries that came with it.

These lithium batteries charge quickly and have a rapid recharge time. I can rely on them for fast power replenishment.

It's a decent battery I've got 6 of them and I'm glad the price dropped on them. They all are still holding charge and working as expected

These lithium batteries deliver reliable and efficient power. They consistently perform at a high level.
