What are the advantages of the Temgot LiFePO4 battery?

Firstly, our lifepo4 batteries use the most up-to-date grade A cells technology, In addition, Temgot 12.8 volt lithium-ion batteries feature an advanced and efficient BMS system. Finally, we provide a 5-year industry-leading warranty on all Temgot lifepo4 batteries.

How many Temgot 12.8 volt lithium ion batteries can I connect to at most?

Our 12.8 volt lithium ion batteries come with an external activation switch, which can be used to turn off the battery, and the BMS with one key when the battery is not needed to work. In this way, it can reduce the self-consumption of the 12 volt rechargeable battery, making it safer to store and prolong the battery life.

What's the best way to use them?

Use 14.6V lithium battery charger to maximize the capacity. the recommended Charging voltage: Between 14.2V to 14.6V.12v 300Ah

1. 60A(0.2C)The battery will be fully charged in around 5hrs to 100%capacity.
2. 150A(0.5C) The battery will be fully charged in around 2hrs to 97%capacity.

Will cold weather affect my battery?

Your Temgot Lithium battery will discharge normally between a range of -4F and 140F (-20C to 60C). 12.8V 300AH batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures.

Are Lithium Batteries Safe?

Temgot Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Temgot Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof IP65 case. For best performance & reliability we recommend using a LiFePO4 charger.
