The case seems quite sturdy and the terminals feel very secure. This is a whole lot of battery for the money. It's installed now and working as intended. I couldn't get the Elefast app to download so I used the overkill solar app and it works fine with the BMS. I don't think you could buy cells, case and BMS for this price. I hooked it to a 2500 watt inverter and ran it to its capacity with resistive loads and the battery performed as it should. I couldn’t be happier with it. Review: Excellent balance. It’s a little bigger than specs say. - There’s a free Bluetooth app to look at battery status, but it doesn’t let you do anything useful. I had to spend another eight dollars to get the Bluetooth app that allows one to control the battery. Not a huge deal, but I had to go “really?” Actual capacity was higher by about 13%. Nice. Without going into the knee, Cell differentials seemed to max out at about 2 mV. Excellent. Good quality workmanship. Good packaging for the shipment. My only complaint was that the dimensions quoted are a bit off. Actual dimensions are slightly larger. I measured 7.6 inches width (includes the joint between bottom and top of case) 15.1 inches length (includes the lifting handles) 10.4 inches height (includes the terminal bolts. A box of these dimensions would give an extremely tight fit. One should allow at least another half inch in height, to allow for connections. An additional inch would be a very good idea. Don’t forget about ventilation. I will need to do a bit of carpentry to make this fit the intended space. Recommend this battery. ## Features - 【EVE Grade A+ Cells】300ah 12v lithium battery using EVE Grade A+ Cells high-end battery cells, higher energy density, more stable performance,15% stronger than other lithium batteries of the same size,especially the balance of the voltage performance is very strong,stable voltage will not damage your appliances,you can rest assured that the use. - 【Designed for RVs】300 ah lifepo4 battery 12v Saving 40% space and 50% weight,energy density increases to 78wh/lbs; lithium iron phosphate battery is the perfect replacement for lead- acid batteries,the 300ah lifepo4 battery supports solar charging,and is a must-have for outdoor RVs and off-grid equipment. - 【200A BMS & Multiple Protection】12v 300ah rv battery built-in 200A intelligent BMS battery management system prevents overcharging,over-discharging,overloading,high temperature and short-circuit;low-temperature protection mechanism,the BMS will cut off immediately when the temperature sensor detects the battery temperature is below -4℉ or above 132℉. - 【Deep Cycle 8000 & Bluetooth APP】300ah deep cycle battery Each Cells voltage balancing ability is excellent, balanced voltage can extend the life of the battery,the number of cycles up to 8000 times or more,the battery life up to 10 years or more.

I also connected an inverter to it. It has Bluetooth functionality, so I can monitor the battery status directly from my phone. Everything works great and installation was easy. --- ## 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.tn/products/693746521-elefast-12v-300ah-lifepo4-battery-12v-lithium-rv-battery-200a](https://www.desertcart.tn/products/693746521-elefast-12v-300ah-lifepo4-battery-12v-lithium-rv-battery-200a) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-26*
