FAQ

A: With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume.

A: Our batteries are safe. All Junlee batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS).The BMS protects the cells against excessively high or low voltages, high currents, short circuits, and excessive heat or cold. These are the most common causes of battery failures, and we have taken every precaution to mitigate these risks in all of our batteries.

A: In most standard 12, 24, or 48 volt systems the best choice of lithium battery is LiFePO4 (Lithium Iron Phosphate). The voltage of this type of battery is very similar to an AGM and will work great with readily available system components for your RV, boat, or off-grid power system.

Working time =1036Wh* 0.9 / operating power of the device you are using.

All TTNergy energy storage systems have built-in MPPT controllers including BlackBee 1000.

You need to check if the LCD Battery Display showing the input power (watts). If so, this means your BlackBee 1000 is charging.

Technically, yes, you can but not recommended for sure. As being over-charged is harmful to the battery and bad for its life span. On the other hand, it might also pose a safety risk for the user.

Yes, you can. It is 100% safe and reliable used indoor.
