(5) Batteries fit in the space just fine.

I replaced 2 55Ah deep cycle flooded lead acid batteries weighing total of 100 lbs with this 300Ah battey. I saved 50 lbs from my trailer tongue, got room in my double battery box for aRedArc charger and 24V power converter for starlink. Shower runs better, water pump does not struggle on lower voltage and generator cranks harder for quicker starts.This battery makes a big difference for dry camping for several days even if overcast and solar can’t charge it much there are plenty of electrons left for another day

works amazing no drop in power at all , with the refrigerator , toaster oven, ps5 and tv , along with coffee maker and washer , still above 13v . the sealed batteries would be at 12.2 by then . night and day

Battery is working great. Super small size for huge power!

These batteries seem to be very good so far

Great Battery. Everything as expected and described. I liked the overall weight and size for a 300 ah battery. Price was also great.

Excellent so far! Going camping with it this weekend

So far so good. Haven't challenged them very hard yet

A friend installed it gor us and it is working great.

Love the mini size for my camper

The shipped and arrived as expected

Failed after only a few months and so far no luck on getting it replaced through warranty

Failed after only a few months. Been trying to get a replacement for weeks and it still hasn't happened.

I will send an email regarding level of service. As a company you are doing a huge disservice with your outsourced service centers. I own 6 Renogy products. May consider other companies going forward.

Product awesome. Customer service is sub par

Great product at a great price. Delivered fast, too.

These batteries are Stout in features, pretty small, considering the size of the regular 300 amp power batteries, they came with instructions in a way to register them online. I gave it five stars for the batteries, but I think that I would only give it two stars for the shipping aspect of it although they arrived in a matter of three and 3 1/2 days every time I would call the Support line they couldn’t give me the shipping information so I could track it myself. again it’s not a dig on the batteries, but I think the logistic side of the house

Great

The size is what mattered, did not fit into my small existing battery space, removed an unused generator and am going to get another battery and put 2 in its place.

so far, so good

Perfect size battery smaller and lighter than most 100ah batteries.
Hopefully they last a long time

works

still trying to get them balanced, bolt thread on one of the batteries seems to be off and not let the bolt lock down

Will be perfect if mppt is incorporated

I have purchased 4 of the 300amp Lithium batteries 6 months ago. The batteries are half the price of a battle born and seem to be of good quality. One of the batteries has gone bad and will not charge. Their warrant process is very long and has not been resolved yet. You will not get the service you get from battle born but at half the price for the same battery is it worth it? I have 4 battle born batteries on my RV for 3 years and no problems as of today. Both are good batteries but Renogy customer service is not American which is a big issue for me.

So far, it’s been a great upgrade. The size allowed us to do minor modifications to the original battery compartment and the available power has been perfect for our off grid needs.

We needed a more reliable battery for our RV. These are working amazingly!

Great battery! Lasted an entire 5 day boondocking trip, recharged by 3 190 watt solar panels no problem. My wife even used her blow dryer, curling iron and the toaster every day running off the inverter. We never fired up our generator.

Good battery. Works well. I like the 5 year warranty.

Two 300 amp hour mini's replaced two 100 amp hr marine deep cycle lead acid batteries... the two mini's changed my life from constantly stressing about battery charge and charging to never having to never having to even think about the charge state of my batteries.

Doing everything it us supposed to to do
