    1. My current RV is using a 12V system, if I upgrade to a 48V system what obvious life improvements will I see?

    The most perceptive advantage of upgrading from 12V to 48V is that you will be able to use high-power electrical appliances in your RV. If you need to use high-power electrical appliances such as an air conditioner, refrigerator, or oven then a 48V battery will meet your energy needs and greatly enhance your off-grid living experience. Also, thinner cables can be used to connect the battery to the rest of this system, this will reduce transmission loss, save on space and improve the safety of your solar setup.

    2. How long can this battery be used for?

    This battery can complete 4500 full charge-discharge cycles and battery efficiency will drop to 80% of factory performance after this, however it can still be used with ease. If you live completely off-grid and charge and discharge the battery once a day it will last for more 10 years.

    3. How many batteries can be connected together at once?

    Up to 12 batteries can be connected in parallel, the auto-balancing function allows you to connect in parallel more safely.

    Amazing performing battery
    I bought 4 of these to start working on my next 4 currently. Love the performance of this battery. It has been great for my wife and I. We live off grid in a yurt in the desert of Joshua tree. I was able to install them in one of my kitchen cabinets nicely and they fit literally perfectly. Went from a 12v system with 700ah of agm Renogy batteries and would be to 40% by morning in battery life and with this new 48v system set up I now have. By morning I am waking up with 82% and can now finally make a coffee without having to wait for the sun to recharge the batteries. I highly recommend these as they are fair priced I’m my opinion. I also started with Renogy for my first solar system and have had good luck and good customer service. I know some don’t. I’ve had my share of bad service but always gets resolved in the end.

  2. Great 10awg extensions

    48V 50ah Lithium Battery
    Very well housed battery. Easy to parallel with my other 48V 50ah Renogy Litium Fe battery and connect to my Lycan 5000.

    Not as smart as I wanted
    I have 4 in parallel and it is working perfectly. The on off switch is great when connecting to your inverter or rewiring. The add on display is pretty frustrating. It will not stay on any page, It autocycles constantly and at an absurdly slow rate. The SOC percentage (add on display) is on a shunt so it is pretty accurate but It sucks waiting 10 seconds to see the SOS% I am happy I have these but its worth mentioning to TAKE NOTE OF THE CHARGE VOLTAGE IN THE MANUAL These batteries are LifePo4 BUT they are 15S, 15 internally series, Not 16S like some of the other brands, Makes no difference to AH, but my AIMS inverter has a AC charger in it that I cant use because it is set to 16S and not configurable. On the plus side(for longevity), having it 15S makes the low voltage disconnect on my inverter cut at a higher voltage per cell which I do like. Overall,Im happy, but its not a very smart battery aside from the heating function….

    Good battery
    I am using the battery salon be with the Renogy solar charger and inverter to provide power in a high tunnel. Or has performss well. I have been using the system to provide electricity for the heater. I would like to see recommended settings to use the battery and charger together, but so far it is working well with the tweaked settings.

    Great battery
    Works well. I have two of these batteries now.

  7. fowler.elec

    Documentation is lacking
    I bought this to set up an online backup system for my home network and server. It works great, bur I was hoping to use either the RS485 or CAN port to monitor the battery. It does not appear that the ports are published to allow system integrators to make use of the product in any system. I also have concerns the pinout on those ports does not follow the typical pinout for an Ethernet cable which means the differential pair is split across a pair when using an ethernet cable to patch them together.
