Run Time (hours) = Battery Capacity (Ah) / Current (A)

The higher the discharge rate (amount of current/amps being drawn from the battery), the shorter the duration it will last.

For example:

A 200Ah battery discharging at just 10A could theoretically last around 20 hours. Discharging at 50A would last only around 4 hours.

The BMS boards are different. The 200Ah battery uses a 100A BMS, which can accept a maximum continuous charge/discharge current of 100A. The Plus version uses a 200A BMS, which can accept a maximum continuous charge/discharge current of 200A.

Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are UL certified for the highest safety and sustainability standards. All LiTime LiFePO4 batteries come with an internal Battery Management System which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection – protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.

No. This battery is not compatible with the Bluetooth module. You can use a 500A Battery Monitor With Shunt to keep track of battery status.

No. LiTime LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

1. Using Solar Panels

The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 800W solar panels. It may take more than one day to fully charge the battery by ≥800W solar panels since the duration and intensity of light would be a great factor for their charging efficiency. Besides solar panels, there are 2 more ways to charge.

2. Generator/Alternator

If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

3. LiFePO4 Smart Chargers

To charge 12V battery, it is recommended to use 14.6V battery charger.  The Recommended Charging Voltage: 14.2V - 14.6V.  The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

It is recommended to disconnect the charger from the battery or unplug the charger plug from the socket when the storage battery is fully charged. Otherwise, it may cause the battery BMS to trigger overcharging protection.

If BMS protection is frequently triggered, the BMS will be damaged over time, leading to degradation of the battery system performance or even damage.

LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 200Ah  lithium battery doesn't have low-temperature protection, so it suggest to charge the 12V 200Ah deep cycle battery indoor.

It is recommended to store LiTime LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH
