They shipped fast and arrived sooner than anticipated, which was awesome. I had a few questions and the seller answered quick and was super helpful. 10/10 service. Great value for the price! Batteries work as they should, no complaints. ### ⭐⭐⭐⭐⭐ A good deal, excellent battery *by P***G on March 18, 2026* Seems to be an excellent deal. I moved from 5 200AH batteries to 4 of these 600AH batteries. Packaging was excellent. Batteries had tome heft but were easily managable by one person. I was able to use the same battery cables as the previous batteries even though I removed one. These are a bit longer than the previous ones but still fit in the storage bay of my Class A motorhome. We have had a couple of short power outages this winter and I did not have to worry about losing power to the coach with the extra capacity these bring. They leveled up on charge quickly Without BlueTooth capability it's not possible to check indvidual batteries but my Victron system shows the proper capacity and the batteries recharge quickly after use. ## Frequently Bought Together - 12V 300Ah LiFePO4 Lithium Battery, Built-in 200A BMS with 6000+ Deep Cycles Rechargeable 3840Wh Lithium Battery for RV Solar Marine Solar Panel Camping - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - Renogy 12V 60A DC to DC On-Board Battery Charger for Flooded, Gel, AGM, and Lithium, Using Multi-Stage Charging in RVs, Commercial Vehicles, Boats, Yachts, 60A --- ## 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.us/products/712112713-12v-300ah-314ah-lifepo4-lithium-battery-built-in-200a-bms](https://www.desertcart.us/products/712112713-12v-300ah-314ah-lifepo4-lithium-battery-built-in-200a-bms) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-15*
