Features

Details from the MARSENERGY Amazon listing:

• 【Winter Won't Stop You】Marsenergy's self-heating LiFePO4 battery utilizes A+ grade cells with enhanced low-temp additives, delivering improved cold-weather performance compared to standard lithium batteries. The built-in 60W heating system automatically activates between -4°F and 32°F (BMS cut off below -4°F). Note: Heating draws 5A from the charger, reducing charge speed during cold operation
• 【Bluetooth Monitoring】 Marsenergy 12V 100Ah LiFePO4 battery features Bluetooth connectivity for real-time monitoring of voltage, current, state of charge (SOC), and temperature. Simply scan the QR code using our dedicated app (Android/iOS compatible) to establish a stable connection within seconds. The app download QR code is on the back of the battery
• 【10-year lifespan】Under the correct usage, after our rigorous testing, Marsenergy 12v 100ah lifepo4 battery can keep 100% Depth of discharge(DOD) after 4500 deep cycles, 80% DOD after 8000 deep cycles, and 60% DOD after 15000 deep cycles. Traditional lead-acid batteries only have 300-500 cycles, and their service life is only 1/10 of that of our deep cycle battery
• 【Smaller and lighter】Marsenergy 12v 100ah lithium battery weighs only 21lb, much lighter than traditional lead-acid battery. It size is 10.16*8.46*6.54 inches, which perfectly meets the BCI Group 24 standard. If you previously had a Group 24 lead-acid battery box, you can directly upgrade to a lithium battery. If you have a larger battery box such as Group 27 or 31, it is still compatible
• 【Safety Guarantee】Marsenergy lithium batteries 12v uses A-grade cells, and the BMS board has multiple safety protection functions. Once the BMS detects that the battery is in an abnormal state (short circuit, over-voltage, abnormal temp etc.), it will immediately cut off the power and put the battery into sleep mode to protect the safety of you and your family. (The battery in sleep mode needs to be activated before it can be used again. Please refer to the user manual or contact us)
• 【Up to 4 Series and 4 Parallels】Marsenergy 12 volt lithium batteries support parallel and series connection to expand their capacity or voltage. The batteries system can be 51.2V 400AH (4S4P), with a maximum energy of up to 20.48kWh
