The compact Group 24 size (10.23×6.61×8.46 in) fits most standard battery boxes, so it’s easy to carry, install, and swap out. If you’re replacing a 12 volt LiFePO4 battery or a traditional RV battery in a camper or trailer, this is a true drop-in replacement. - 【IP65 & 100A BMS – Marine Ready】 With IP65 waterproof protection, this 12V 100Ah LiFePO4 battery stands up to dust and water spray—handy for a marine battery, boat, or trolling motor battery. The built-in 100A BMS protects both the 12v battery and your devices from overcharge, over-discharge, overcurrent, and short circuit. Just note IP65 is for water spray, not immersion. - 【1280Wh & 4000+ Cycles – 5-Year Warranty】 Using Grade A LiFePO4 cells, this lithium battery 12v 100ah mini delivers 1280Wh of energy, 4000+ cycles at 100% DOD, and up to 15,000 cycles at 60% DOD. It’s backed by a 5-year warranty and up to 10-year design life. As a deep cycle battery 12v, it works well for solar battery storage and home energy storage. To help extend 12v 100 amp hour battery life, charge and discharge it once every 6 months when not in use. - 【4S4P Expandable to 20.48kWh】 Need more capacity? You can connect up to 4S4P—series and parallel—using 16 identical 12V 100Ah lithium batteries to build a 51.2V 400Ah 20.48kWh system. The built-in BMS supports cell balancing and multi-battery operation. It’s a flexible setup for RV battery systems, solar battery storage, and off-grid power. - 【Low-Temp Cutoff & 24h Support】 Charging works from 5°C to 65°C, and discharging works from -20°C to 70°C. You can charge with a 12V LiFePO4 charger, a solar MPPT/PWM controller in lithium mode, or a generator paired with a lithium/DC-DC charger. Backed by 24h customer service, this outdoor battery is a reliable choice for your adventures. For energy storage only—not for engine starting. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FBWJWJ92 | | Automotive Fit Type | Universal Fit | | Battery Capacity | 100 amp_hours | | Battery Type | Lithium Ion | | Best Sellers Rank | #5,451 in Automotive ( See Top 100 in Automotive ) #22 in Automotive Replacement Batteries | | Brand Name | dumfume | | Compatible with Vehicle Type | RV | | Customer Reviews | 4.4 4.4 out of 5 stars (835) | | Item Dimensions D x W x H | 6.61"D x 10.23"W x 8.46"H | | Item Highlight | 1280Wh IP65 Waterproof 15000 Deep Cycle Battery for RV, Solar, Marine, Trolling Motor, Off-Grid, Home Energy Storage | | Item Weight | 21.6 pounds | | Manufacturer | dumfume | | Manufacturer Part Number | 1 PCS 12.8V 100AH MINI | | Manufacturer Warranty Description | 5 Year | | Model Number | 12.8V 100AH MINI | | Number of Items | 1 | | Size | (10.23×6.61×8.46in)12V100AH MINI | | Terminal | M8 | | Voltage | 12.8 volts | ## Product Details - **Battery Capacity:** 100 amp_hours - **Battery Cell Composition:** Lithium Ion - **Brand:** dumfume - **Item Weight:** 21.6 pounds - **Product Dimensions:** 6.61"D x 10.23"W x 8.46"H - **Size:** (10.23×6.61×8.46in)12V100AH MINI - **Terminal:** M8 - **Vehicle Service Type:** RV - **Voltage:** 12.8 volts ## Images ![12.8V 100Ah Mini Lithium LiFePO4 Battery Group 24 100A BMS Low-Temp Cut off - Image 1](https://m.media-amazon.com/images/I/71pwPadE3GL.jpg) ## Available Options This product comes in different **Set** options. ## Questions & Answers **Q: Any tips for connecting batteries in series or parallel?** A: Yes – fully charge each battery first. Use the same brand, model, capacity, and BMS, and buy them within 3–6 months of each other. For multiple connections, use a bus bar. **Q: Can I use the battery right after delivery?** A: For shipping safety, it comes with ≤40% charge. Fully charge it before first use. **Q: Can I use this battery on a boat?** A: Yes, as a service battery for things like a fridge or coffee maker. Keep it dry and away from water. Not for starting engines or trolling motors. **Q: Can I charge or discharge it in cold weather?** A: Discharge works from -4°F (-20°C) to 140°F (60°C). But never charge below 32°F (0°C) – it damages the cells. The BMS will block charging. In winter, bring it indoors above 41°F (5°C) before charging. **Q: Does the package include a LiFePO4 charger?** A: No. Please use only a dedicated 14.6V LiFePO4 smart charger. Using a regular lead-acid or other lithium charger can damage the battery. ## Frequently Bought Together - Dumfume 12V 100Ah Mini LiFePO4 Lithium Battery 100A BMS 1280W Rechargeable Lithium Iron Phosphate Battery 6000+ Cycles 10-Year Lifespan Perfect for RV, Solar, Marine and Home Energy Storage - ECO-WORTHY Solar Connectors Y Branch Parallel PV Adapter Cable Wire Plug Tool Kit for Solar Panel(M/FF+F/MM) - SUNMAK 16 Units per Set Solar Panel Mounting Z Brackets, Solar Panel Mounting Brackets Lightweight Aluminum Corrosion-Free for RVs, Trailers, Boats, Yachts, Wall and Other Off Gird Roof --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/735539751-12-8v-100ah-mini-lithium-lifepo4-battery-group-24-100a](https://www.desertcart.sk/products/735539751-12-8v-100ah-mini-lithium-lifepo4-battery-group-24-100a) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-13*
