The LiTime 12V 165Ah lithium battery delivers a robust 2112Wh of energy capacity. Depending on the load, it can support an 1100W air conditioner for 1.92 hours, a 1000W electric grill for 2.11 hours, or a 900W coffee maker for 2.34 hours
New batteries typically arrive with a low state of charge (SOC) due to shipping regulations. To maintain peak performance and prevent over-discharge, please charge yours immediately upon arrival. For Bluetooth-enabled models like the 12V 165Ah battery, the unit is shipped in a "power-off" state with a terminal voltage between 3V and 5V to minimize self-discharge. To activate the battery and enable Bluetooth connectivity, simply connect it to an AC-DC lithium charger or an MPPT solar controller for 3 to 10 seconds. For long-term storage, keep the battery at 50% SOC and perform maintenance every three months.
The LiTime 12V 165Ah battery can be charged in four different ways:
1. Solar Panels and Controller
2. Battery Charger
Tip: It's advisable to disconnect the charger from the battery once charging is complete.
3. Generator
4. Alternator
By utilizing these charging methods, you can efficiently maintain the performance and longevity of your LiTime 12V 165Ah battery.
This configuration is highly discouraged. While Bluetooth-enabled batteries allow for individual monitoring, the system as a whole cannot be tracked collectively. Mixing different battery types may lead to reduced total capacity and compromised system performance.
Group 31 lithium batteries are physically larger and have higher capacity/energy than Group 24 batteries. Group 24 units are smaller with lower Ah capacity, while Group 31 units deliver more power and longer runtimes in the same battery category.Learn more about differences Between Group 24 VS Group 31 Battery.
