TezePower 12V 200Ah LiFePO4 Battery with Bluetooth, Self-heating and Active Balancer, Built-in Smart 200A Daly BMS

Automatic Self-Heating Function: 

Please note: The heating function is automatic and not manual. The heating module is an independent module that is not controlled by the Bluetooth app. Therefore, the heating function cannot be adjusted through the Bluetooth app. The heating function will only automatically activate when the ambient temperature drops below 0°C (32°F).

Intelligent temperature control: The self-heating function automatically activates in environments between -20°C to 5°C (-4°F to 41°F).
Precise Adjustment: Automatically stops heating when the battery reaches 5°C/41°F and begins normal charging.
External Power Supply: Uses the charger/controller's current rather than consuming the battery's own energy for more flexibility and efficiency.  
Notes on Use: The battery must be placed below 0°C for self-heating to activate automatically. Please check this video for more details: https://www.youtube.com/watch?v=GA_DfhawRpw&t=14s

Grade-A Cells And Upgraded BMS: TezePower LiFePO4 Battery 12.8V 200Ah has built-in Daly 200A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, short circuits, and the high-temperature cut-off for increased performance and longer life.

Deep Cycle&High Quality&Safe: Lithium iron phosphate batteries have CE certificates and pass UN 38.3, and MSDS Tests. But also offer over 10 years of lifespan by 8× more than lead-acid batteries with more than 4000+ cycles (95% DOD). With its safety and stability, the LiFePO4 battery can perfectly replace the traditional lead acid battery. TezePower Lithium iron Battery is made from 100% safe, non-toxic, and not hazardous energy, LiFePO4 batterie has higher chemical stability, is not prone to thermal runaway, and will not overheat or catch on fire even if punctured. With no acid in the battery, you're able to safely mount it in any position.
