Review: You need one!! - Awesome battery, I love it! 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: Great battery, super value. - Why did you pick this product vs others?: I bought this after sending back another Li battery that was just a train wreck. 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.

## 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. And highest-level safety is based on UL Testing Reports for the cells inside the battery and upgraded BMS with heating pads to protect it from overcharging, over-discharging, over-current, and short circuits with excellent self-discharge rate.
- 【APP MONITORING】 Our batteries have listened to the suggestions of many users, so we have made a special battery with a communication function so that you can easily monitor the status of your battery in real time. This includes current, voltage, temperature, cycle, etc. Just download our APP on the phone according to the instructions. It brings great convenience to the user experience.
- 【Automatic Self-Heating】The 12V 100Ah LiFePO4 battery is equipped with an automatic self-heating function that will be activated by the BMS when the battery is connected to a charger at temperatures below 32°F. Heating will stop when the battery temperature reaches 41°F, and then the battery will start charging normally. This feature makes it possible to charge the battery at low temperatures without any issues. The battery’s operating environment is no longer restricted, making it more flexible and convenient to use.
- 【Safety & Unlimited Solar Energy】 The stable Lithium Iron Phosphate chemical structure makes LiFePO4 battery not burn or explode even at high temperature, short circuit, impact and drop. And it does not contain any heavy metals and rare metals and is more energy efficient, clean, green charging , which called green battery.
- 【Multi-Application】 With no acid in the lithium ion battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, travel trailer, and off-grid applications! NOTE: The battery is suitable for energy storage rather than start-up. Please consult us in advance if needed.
- 【Kindly Attention】This battery with self-heating can not be connected with the regular version 12V 100Ah battery model in series or in parallel. The battery will activate the heating function only when the charging current is more than 10A.

The “manual” was actually pretty good. Packaging was completely adequate. The heated battery function works well and faster than I anticipated.
