- 40B19L BATTERY TYPE - 12 Volt; 22AH; CCA680; Weight: 3.1kg / 6.8 Lbs; Terminal[- +]; Dimensions(LxWxH): 196x127x202mm / 7.7x5.0x7.9inch; Chemistry: Lithium Phosphate Ion ( LiFePO4). KEPWORTH LiFePO4 Battery can be charged and discharged repeatedly (Charging efficiency is three times faster than lead-acid batteries)
- LiFePO4 BATTERY REPLACES LEAD-ACID BATTERY: Measurement standards of lead-acid battery and lifepo4 battery are different,can be regarded as number of lifepo4 divided by two,equivalent to the capacity of lead acid battery.(E.g: 50Ah for lifepo4 battery is equivalent to 100Ah for lead acid battery,but the starting current is the same as that for lead acid 100Ah)
- BUILT-IN BMS - BMS stands for "Battery Management System" - the brain of our deep cycle lithium batteries. It can turn off the power automatic while the battery under-voltage and regulates the amount of power taken out of the battery and acts as a shut-off system to protect the battery (and you) from unsafe operating conditions.
- ✅ BUILT TO LAST: Our 12V 36Ah LiFePO4 Batteries live more than 2000 cycles at 80% depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge. This basically means a LiFePO4 battery will last you at least 5 times longer than a lead-acid battery, which actually reduces overall cost.
- ✅ LIGHTWEIGHT AND VERSATILE: Compared to lead-acid batteries, lithium provides greater energy density and are at least 1/2 the mass, it is a perfect upgrade for 12V 35Ah 50Ah Deep Cycle battery, and best choice for many applications such as Mobility Scooter, Power Wheelchair, Fish Finders, Ice Fishing, Camping, Solar System, Home Alarm Systems. Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series or parallel.
- ✅ AUTOMATIC BMS AND LOW TEMPERATURE CUT-OFF : The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second(No longer need a higher voltage input to activate). Besides, charging low temperature cut-off function will cut off the battery when the temperature below 32°F to ensure safe use and battery performance.
- ✅ SAFE AND ENVIRONMENTALLY FRIENDLY: Made from 100% safe, nontoxic, not hazardous energy, Weize LiFePO4 battery has higher chemical stability, it 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 in any position. BUT please read the user manual carefully before using, don't hesitate to call us if you have any questions about the battery.
