No regrets as it's my first "real" battery that doesn't weigh a ton!! I got it to replace the old lead-acid Interstate. BT function is nice and the dashboard tells me everything I need to know. I'm no electrician but it has all the "info" and then some. All I need to know is what circuit is pulling what and I can switch off circuits as needed. Heated function is nice as I use it out at my tiny camp in the woods. I wouldn't leave it unattended for a long time, it goes with me. It runs a 19",12v TV, USB light strips, and charging ports. A heated blanket is available but I only use that for emergencies! It will also be used in my 4x8 tiny camper that I'm building! Haven't given it a heavy duty test or anything but I just use it for my own personal light camping or "glamping". In the tiny camper, its hooked up to a 12 space fuse box which I only have 6 circuits hooked up. 12v TV with Roku, heated blanket, charging and lots of lighting. I also have a 6 space, wireless fuse box wired off it as well. All just lighting circuits. The charger is hooked up to a shore power outlet so it charges fast with the flick of a switch. Usually just a couple hours with the charger. I do not have any solar panels, but I'm waiting to get those, it's a new build and it's not outside yet. There is a couple DC outlets and USB chargers built into an entertainment stand. One wall light with a ceiling light over the sleeping area. Wireless switched lights in the middle and over the kitchen. Wireless switched exterior lights front and back. Wireless switched green underglow lighting with 10 green marker lights front and back. It runs everything great without a problem! I shorted it out a couple times installing lights but it just resets and its working just fine! I built my entire tiny camper around this battery! It does not disappoint! It just sits on the floor in the battery cabinet. It fits right in the middle and looks good if you ignore my wild wiring!! Got some trim around the bottom to keep it in place. I think its a great value for those who like quality and need a solid base to build from! I will upgrade the camper battery to a 200ah. I have a matching Vatrer, 2000w inverter waiting to be installed. I'm gonna keep this 100ah as my buddy battery! It will go everywhere I go; camp, camper, treehouse, campervan, tiny house and off-grid systems for my mobile home! It will start all my future builds as the workhorse and the one that keeps me moving forward! Review: Easy to carry down my 40-step stairway to my boatlift. - 👌Arrived on time and in good visual shape. The box packing was adequate. Placed it on my Vatrer 20A 12V charger without any trouble after I unplugged the charger from the socket to re-set it and it started up right away. I anticipate this battery to be as reliable as the 38-volt battery that I purchased earlier for my golf car. ## Features - 【Grade-A Cells & Upgraded 100A BMS】VATRER POWER 100Ah self-heating LiFePO4 batteries with Automotive Grade A LiFePO4 cells have uncompromising quality and higher energy density with better stability, which makes it possible to ensure long-term recycling.

The Vatrer used to be a piece of crap with really poor build quality, but recently they have totally reworked the design into a really solid item at a great price. Mine arrived at about 60% charge, instantly started charging and balancing when put into my solar system. The 4 cells are usually with .001 volt of one another at all times so it stays amazingly well balanced. It's the plug and play Li battery I was hoping for. Will Prowse has a new video mentioning this battery and the build quality (the 3 year old video of the same shows the old battery now d/c'd.) The Vatrer app is easy to use and is within 1% of the reading of my Victron shunt, so maybe not perfect but certainly close enough for practical use. ## Frequently Bought Together - VATRER POWER 24V 200AH Bluetooth Low/High Temp Cutoff LiFePO4 Lithium Battery with Self-Heating, Built-in 200A BMS, Rechargeable Battery with 5.12kW for RV/Camper, Solar Home & Off-Grid Setup, Backup - 10pcs 1 AWG-3/8 Battery Lugs,Copper Wire Lugs,UL Listed Heavy Duty Battery Cable Ends,Tubular Ring Terminals,AWG Crimp Wire Ring Lugs,Battery Terminal Connectors with 3:1 Heat Shrink Tubing - Sanuke 10pcs 1/0 AWG-3/8 Battery Lugs, UL Listed Heavy Duty Wire Lugs Ring Terminal 0 Guage terminals Battery Cable Ends/Terminal Connectors with 3:1 Heat Shrink Tubing --- ## 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/652182422-12-8v-100ah-group-31-lifepo4-lithium-battery-self-heating](https://www.desertcart.us/products/652182422-12-8v-100ah-group-31-lifepo4-lithium-battery-self-heating) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-11*
