Product Details
✓【Automatic Self-Heating】12V 300Ah LiFePO4 battery model is equipped with an automatic self-heating function that will be activated by the BMS when the battery is connected to a charger at -4°F to 41°F. The heating will be stopped when the battery temperature reaches 41°F and then the battery will be formally charged. This feature makes it no problem to charge the battery at low temperatures. The battery's working environment is no longer restricted, but more flexible and convenient to use.
✓【Grade-A Cells & Upgraded 200A BMS】VATRER POWER 300Ah self-heating LiFePO4 batteries with Automotive Grade 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.
✓【Exceptional Longevity & Lightweight】 Our LiFePO4 lithium iron batteries provides 5000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times than the standard lead-acid batteries. Helping to minimize replacement cost and reduce total cost of ownership. And the weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity, so you can carry it more easily.
✓【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 300Ah battery model in series or in parallel. The battery will activate the heating function only when the charging current is more than 10A.
✓【NOTE】The 300Ah heating battery adopts our latest appearance design. All the configurations are the same as the previous version. It can still be connected in series or parallel with the earlier version.
