Quick take
When you need a dependable 12V lithium iron phosphate battery for a boat, RV, trolling motor, or off-grid solar setup, the marine electrical batteries lighting section is full of options that look surprisingly similar. These four listings all feature 100Ah capacity and 100A continuous current ratings, but they split into two very different approaches. One listing offers a range of 100-300Ah capacity and the lowest listed price, while another adds Bluetooth monitoring and low-temperature charging cutoff for a higher price. Two of the listings are the same WERCHTAY battery sold at different listed prices, so the real decision is whether you need the monitoring features, the capacity flexibility, or the simplest 100Ah package at the lowest available price.

Product notes
100AH 300AH LiFePO4 12V Lithium Battery BMS Solar RV 15000 Deep Cycles RV Marine
The KEPWORTH battery stands out for its capacity range: the listing shows 100-300Ah, which gives you more flexibility if you're building up a larger system or need extra runtime. Its 100A BMS and 100A continuous charge/discharge ratings match the other batteries here, and the application focus on high-drain devices makes it a good match for trolling motors or inverter loads. On the other hand, it leaves out the Bluetooth monitoring and low-temperature charging protection that the DC HOUSE battery includes. If you want to track voltage and current from your phone or need protection when charging in cold conditions, this isn't the one.
12V 100Ah Lithium Battery 4000+ Deep Cycle LiFePO4 BMS RV Solar Marine Off-Grid
The DC HOUSE battery is the only listing in this set that explicitly includes Bluetooth 5.1 monitoring and a low-temperature charging cutoff that stops charging when the sensor detects temperatures below 32°F. That makes it a practical choice for year-round marine or RV use, and it also lists a 130A discharge peak for 10 seconds. The trade-off is that it has the highest listed price in this comparison, and the capacity is fixed at 100Ah rather than the 100-300Ah range shown on the KEPWORTH. If you're willing to pay for the extra visibility and cold-weather protection, this is the feature-packed option.
12V 100Ah LiFePO4 Battery Lithium 15000+ Cycles BMS for RV Solar Marine Off Grid (higher listed price)
This is the higher-priced WERCHTAY listing in this comparison. It carries the same core specs as the DC HOUSE and KEPWORTH: 12V, 100Ah, and a max continuous discharge current of 100A. It also lists an energy rating of 1280Wh and is designed for RV, trolling motor, off-grid solar, and camper van use. The catch here is that the same title and attributes appear on another listing in this guide at a lower price, so you'll want to compare those two before choosing this one. Without Bluetooth or low-temp cutoff, this model relies on the BMS for protection and doesn't offer remote monitoring.
12V 100Ah LiFePO4 Battery Lithium 15000+ Cycles BMS for RV Solar Marine Off Grid (lower listed price)
This is the lower-priced WERCHTAY listing with the same title and specs as the other one. It still gives you the 12V 100Ah LiFePO4 package, 1280Wh of energy capacity, and a 100A max continuous discharge current, all in a format aimed at RVs, trolling motors, and off-grid solar systems. Because the features are identical to the higher-priced WERCHTAY listing, this lower listed price is the one to pick if this is the battery style you want. The limitation is the same: it doesn't include Bluetooth or low-temperature charging protection, so it lacks the monitoring and cold-weather features of the DC HOUSE model.
Final recommendation
If you want the most capacity flexibility and the lowest listed price in this set, the KEPWORTH 100-300Ah battery is a straightforward choice. If you need Bluetooth monitoring and low-temp charging cutoff, the DC HOUSE battery is the one that includes those features, despite the higher listed cost. For a balanced 100Ah option that covers the standard RV and off-grid applications, the lower-priced WERCHTAY listing gives you the same specs as its twin at a lower listed price. Choose that one over the higher-priced WERCHTAY if all else is equal.
