Style: 100Ah Battery
Got tired of adding water to both of my 5 year old deep discharge flooded lead acid house batteries for my RV. My battery compartment is just large enough for two Group 31 batteries and these are near in size to that so I bought two of them. It also helps that the price on Amazon is very good! They look good and were easy to install. Quality looks very good, though that's just a visual check at this point in time for me. Note that the terminals have M8 screws - if you get battery cables with M8 (5/16) lugs there will be more metal at the end vs the 3/8 holes on my previous cables which rotted away. Nice removable caps on the battery terminals which help when connecting multiple batteries in parallel. See my photo of the final installation. I bought a Victron SmartShunt IP65 along with the batteries so that I would have more confidence in the state of the batteries when boondocking without shore (120VAC) power. There is a good datasheet for this battery on the Renogy website but that does not include two parameters that can help accuracy with the Victron. So I asked Renogy customer service for the information which they quickly provided! Bravo to them for this! The two parameters and their value are : Peukert’s Constant: 1.1 and Charge Efficiency: 90% I felt that the old batteries didn't have sufficient remaining capacity - though they were originally 120Ah each. Whether that was true or not I really don't know. See below for the reasons for this and why I got the Victron monitor - which I really like. I have a Renogy Rover 30A solar charger which shows the battery voltage and some kind of state of charge (SOC) number. But the voltage on a lead acid battery is an accurate measure of SOC only if the battery has sat completely idle (i.e. disconnected) for at least 24 hours which is a non-starter when you are camping. The solar controller doesn't know how much current is being drawn from my battery pack (both the house load and solar are connected directly to the battery) so it can't calculate any kind of reasonable load drop. From what I read the loaded voltage could be 0.5 to 0.7v or more below the resting voltage as related to SOC. Hence the uncertainty with the old batteries. The shunt battery monitor is in series with the negative battery terminals so it knows all the current in/out of the battery, plus voltages and temperature. So it can calculate SOC more accurately. Note, however, that all it can calculate is the percentage of the battery capacity. If you enter 200Ah as the net capacity for the battery pack and you use 100Ah then it will show roughly 50%. But just exactly what the net remaining capacity is for a battery that is a couple of years old is a difficult question to answer. If the actual capacity has degraded to 150Ah, then that 100Ah discharge is bringing SOC down to 33% which is definitely not good. Apparently the correct way to test actual capacity is to discharge it at the spec rate (100Ah divided by 10 hours equals 10A) until the voltage drops to 10.5V. You want the current to be constant even though the voltage is varying and you definitely want to stop when you get to 10.5V and then immediately charge it up again. I don't see myself setting up such a test fixture nor do I know any place that can do this kind of test...

Finding this Renogy 6V 260AH deep cycle AGM battery on Amazon was a miracle! 🙌 It’s super heavy, so be prepared to lift it with 2+ people 😅, but it works perfectly for machinery, backup power, or large trucks. Reliable, strong, and exactly what I needed! ⭐⭐⭐⭐⭐

These batteries are EMP proof and will outlast any lithium electrons BMS board when a lightning strikes near by. Or spontaneous start a fire, Been there done that. When we were at a campground and a RV a few camp sites down lost his RV because of a bad BMS didn't work right. Everybody packed the stuff and left while his million dollar motorhome went up in smoke. The likelihood of these batteries doing that are slim to none. We installed a Bluesea battery fuse on top of battery post on 200Ah. Also lithium batteries produced very toxic chemicals when they burn. I seen video's of van and RVers putting these time bombs inside there RV on even under there beds. WHY only to get a little more time on a charge. ALL batteries will go dead and need to be recharged sometime. So what's the point AMG can operate in colder and hotter temperatures with out worrying about a fire or having a BMS cut you off when its 28 degrees. Old tech is where I'll put my money. Just use one battery to keep weight down and use solar and a good Honda generator when and it will happen your battery dies. One other thing never let your batteries go pass 50% SOC. We have a solar system that uses LA batteries and we gotten over 7 years on them because we only go down to 50%. Lithium is like ever new toy on the block everyone has to have them unit they don't. What is new today will become old tomorrow when new tech sells you a new scam. Alway have a generator you can beat them for longevity and use. It's the Greeneys selling you these batteries save the world with lithium fires ya right. I watch Will P. On utube when he cuts into lithium batteries I see wires everywhere and see fires later with lithium. Watch StacheD training about Lithium fires. Amazing you never see that many video's on lead acid or AMG fires.

I purchased this battery for my camper in November of 2022, basically getting ready for the next spring setting up my new camper with solar panels for off grid usage. In 2023 the performance was kind of ok but not really great. In 2024 the battery was low on power in 30 to 45 minutes. As of this spring 2025, absolutely garbage! I didn't get two seasons of any real good usage out of the $400 battery. I would not ever suggest to anyone to purchase or depend on the life or longevity of this battery. Here in Minnesota we camp from memorial Day through Labor day. $200 a year to have a battery and a camper that doesn't even support it with the solar power supply doesn't make any sense. If anybody is wondering yes the solar panels are putting out plenty of amperage to charge this battery fully, the sun goes down the battery goes dead.

These are great batteries but the one thing I’m not happy with is that the terminals are 8mm (metric) and not the industry standard of 3/8”. This makes it a challenge to find a kill switch that can easily be added.
