LiTime 48V 100Ah Server Rack LiFePO4 Lithium Solar Battery

The most obvious improvement of upgrading the 12V system to 48V is that you can use high-power electrical appliances, such as an air conditioner, refrigerator, or oven in your RV to greatly enhance your off-grid living experience. Plus thinner cables can be used to connect the battery to the rest of the 48V system, thus reducing transmission loss, and improving the safety of your solar setup.

1. LiFePO4 Battery Charger

We recommend using a 54.7V battery charger to maximize the capacity

Recommend charging voltage: 53.25V ~ 54.75V

Recommend charging current: 20A (0.2C): the battery will be fully charged in around 5hrs to 100% capacity. 50A (0.5C): the battery will be fully charged in around 2hrs to around 97% capacity.

Attention:

Connect the charger to the battery before connecting it to the grid power in case of sparks.

Remember to disconnect the charger from the battery after fully charging.

2. Solar Panels

The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 1500W solar panels. It may take more than one day to fully charge the battery by ≥1500W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

3. 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: 53.25V - 54.75V.

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.

LiTime 48V 100Ah lithium battery could support Max.4800W load power, and we recommend using a 5000W inverter.

They are different in dimensions. The group 4d battery has dimensions around L21*W9*H10 inch, while group 8d battery has dimensions about L21*W11*H10 inch.

LiTime 48V 100Ah LiFePO4 battery supports the Max. 4800W load power, and you could normally use it under the load lower than 4800W. This 48V 100Ah lithium battery takes the Max. 100 amps.

LiTime LiFePO4 lithium batteries support 4000+ 100% SOC & DOD. If you would like to extend the battery life, we suggest you charging/discharging it to 80% capacity.

The LiTime 48V 100Ah battery, equipped with a built-in 100A BMS, offers 4800Wh of energy, supporting a maximum 4800W load power and a continuous charge/discharge current of up to 100A. Many customers have reported that our 48V solar battery is suitable for use with Ryobi and John Deere electric riding lawn mowers.

Please DO NOT connect LiTime 48V lifepo4 solar batteries in series. LiTime 48v solar battery supports up to 4 identical batteries connected in parallel for up to 48V 400Ah battery bank.

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.

LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 100Ah TM & 230Ah LiFePO4 batteries include low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point.

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
