Features
- P.S. Due to weight, our batteries come one battery per box. For orders of two batteries that are placed on different trucks, the shipments will result in not "Delivered" at the same time. Please be patient.
- Compact & High Energy: GRNOE 12V 100Ah battery measures 12.9*6.7*8.6 inches and weighs 22.48 pounds, which is only 33% of traditional lead-acid batteries, and has an energy density of 57 Wh/Lbs, making it a perfect replacement for SLA/AGM batteries. Our battery life is more than 10 years than traditional batteries, saving you more money.
- Smart Low-Temperature Cut-off: The 12V battery has a low-temperature protection function. The discharge temperature can be as low as -4F. When it is below 32F, BMS will cut off the charging immediately. Widely used in RVs, cabins, or off-grid in cold winter. Advanced BMS protection system protecting the battery from overheating, overcurrent, overcharge, over-discharge and short circuit. P.S. Use an adapter with a voltage of 14.6V0.2V. A 12V charger will not fully charge this battery.
- Reliable & Safe Battery: GRNOE 12V lithium battery adopts advanced A+ grade LifePO4 cells and is UL/UN38.3 certified, with higher energy density and more stable performance. The internal structure is optimized and new structural components are used to make the battery more compact, improve the high performance of the battery and ensure safety.
- Wide Application: The GRNOE 12V 100Ah LiFePO4 battery delivers rapid and reliable power, supporting a max discharge current of 300A for 3 seconds and IP65 waterproof which is very suitable for 12V 36-55lbs trolling motor and can also be used in off-grid systems, RVs battery, home backup, Automotive Replacement Batteries and other fields. P.S. The battery is suitable for Trolling Motors, Marine, Boat rather than Start-Up.
- 3 Warranty and Lifetime Support: Within 36 months from the date of order, excluding human-caused failure events, we will promptly replace the product or Money-Back after confirmation. Welcome reach out to us with any questions, we are always here for you.
- Note:(1)The GRNOE LiFePO4 battery is intended for use as an energy storage purpose, Please do not use this battery as starting batteries, golf cart batteries, or jacks. (2)After first receiving the battery or switching it off, you need to charge the battery using a 14.6V lithium-activation charger to activate the battery (Do not use 12V, lead-acid, or automotive chargers, or chargers with a repair/desulfation mode, as they may interfere with the Battery Management System (BMS) and trigger premature protective shutdown, or even damage the battery.).
- Note:(3)Before connecting batteries in series, please ensure they are fully charged and that the voltage difference does not exceed 0.2V(the battery is considered fully charged when it reaches 14V or higher).(4)To maintain battery health and prevent damage due to inactivity, it is recommended to charge the battery at least once every two or three months.

Have held up great so far.

Style: 48V 100AH
So far everything is working as it should. I was a little confused as to the headline stating it had 10.24kw output. The seller's description uses different electrical metrics to highlight two distinct capabilities: total energy storage capacity and instantaneous power output. 5120 Wh (Energy Capacity): This measures how much total "fuel" is in the tank. It is calculated as 51.2V (the nominal voltage for many 48V systems) × 100Ah = 5120Wh. If the battery is exactly 48V, the capacity is 4800Wh. 10.24 kW (Power Output): This measures the maximum "flow rate" or speed at which the battery can deliver that energy to a heavy load (like a golf cart motor) at a specific moment. This is typically calculated based on the maximum continuous discharge current allowed by the BMS (e.g., 200A × 51.2V = 10,240W or 10.24kW). The little monitor screen only works if you are right next to the battery. The phone app only allows you to view settings but not change anything which I don't know is correct or not. I will use mppt controller and inverter to handle charge settings. I am also using 4/0 AWG flexible welding wire which is overkill but worth it. One last thing: This battery is huge and partial picture on right side. I will update if anything changes.

I bought 8 of these, so I worried I might get scam 15S instead of true 16S 51.2V batteries, then have to deal with the seller on whether they would make it right. (Background: each LiFePO4 cell is 3.2V, so 4 cells in series makes a "12V" battery that outputs 12.8V for most of its discharge cycle, 8S makes a "24V" at 25.6V, and 16S makes a "48V" that is 51.2V. Manufacturers can't get away with shorting a cell in anything less than a 48V battery because it would output less than the nominal voltage, but at 48V, a 15S puts out 48V (3.2 x 15 = 48). This is important if you plan on connecting 15S batteries in parallel with any other 48V LiFePO4 batteries, as their voltages would not match 16S batteries. I haven't torn any down, since I plan on using these. But I've checked 2 of 8 so far, and they test at 53.2V with multimeter, and per BMS, they come charged to 97% SOC (probably 100% at factory followed by some drain d/t smart Bluetooth BMS monitoring and scanning for BT signal). BMS reports 16 cells, average cell voltage 3.323 x 16 = 53.17V, the measured battery voltage. (A 15S could have cell 16's lead attached to another cell for a duplicate reading, but the sum of cell voltages would exceed the battery voltage as you can't fake the overall voltage.) I have yet to do capacity testing. I love that they come with a tiny battery monitor display for at-a-glance battery status so I don't have to open an app and connect to the BMS every time. I plan on sticking them next to the battery combiner (I'm using Victron Lynx Distributors). They only report the SOC, voltage, and the current from the BMS. Oddly, rather than rounding the voltage to the nearest tenth, it truncates (one battery is at 53.17V, but display shows 53.1V instead of 53.2V). On the iOS App Store, the BT battery monitor app is NOT called "Battery Assistant," it's called "Smart Battery Helper," not "Battery Assistant." Once you install the app, it DOES show on your iPhone as "Battery Assistant." Since I have multiple of these batteries, I worried I wouldn't be able to identify which battery the app was connecting to. But when connecting to the smart BMSes, the app shows the BT signal strength: the one with the strongest signal (e.g., –45dB is stronger than –65dB) is the battery your phone is closest to. Just to be sure, I wheeled the battery about 30 feet away when connecting to each battery for the first time, then I wrote the SN on the battery case. So far I'm super pleased with my purchase. I almost bought significantly cheaper 48V batteries, but decided to get slightly more expensive batteries to reduce my risk of getting 15S batteries, and it looks like it paid off!

Thought this would be a great upgrade to my used RV. SO DISAPPOINTED. Charged both batteries with a new 55amp charger. At the end of 12 hours, they were giving two different voltages. Went to put in the coach and only one battery would fit. Started there. Swapped in new charger. Added a kill switch to isolate it from alternator. It's not charging and dies. What a waste of my money.
