Features of OSM48100 48v 100ah Module lithium ion battery bank

OSM48100 makes residential battery storage to a new level. OSM 5 kWh Lithium-Iron Phosphate Battery (LiFePO4), combining superior lithium-iron phosphate technology to provide a better solution to solar energy storage.

The LFP 5Kwh OSM48100 features a battery management system that integrates multilevel safety features including overcharge and deep discharge protection, voltage and temperature observation, cell monitoring and balancing, and a built-in accessible 125 Amp DC breaker On/Off switch. This high-performance Fortress Lithium Battery has a large power capacity, with a fast charging and continuous discharge power, creating a 98% rough-trip conversion. The advanced Lithium Ferro Phosphate (LFP) technology operates a wider temperature range to deliver the most dependable performance. LFP has been proven to be one of the safest Lithium technologies in the industry and is manufactured to the highest standards.

The OSM Lithium-Iron battery is lighter, more compact, and more powerful than traditional lead-acid batteries. Our battery is designed to replace conventional solar battery storage products such as Sealed, AGM, or Gel batteries, utilize your Lithium-Iron battery in off-grid applications, solar energy storage, and more!


LiFePo4 48v 100ah Module Replace your old Battery system.

The initial charge of a disposable battery does attract it as a better buy product. But these batteries die down after certain number of usages. The rechargeable batteries are good enough till they can be recharged. But rechargeable batteries also drain over time. Lithium LFP batteries have a greater thermal stability and long-life span compared to other rechargeable batteries. You can plan to buy LiFePO4 battery which is an extremely stable lithium battery. Apart from longer lifespans these batteries are also not prone to overheating and have a greater tolerance to harsh environmental conditions. Like lead-acid rechargeable batteries lithium batteries are also composed of many cells. Buying OSM48100 48v 100Ah LiFePo4 battery is an extremely simple and efficient idea to save hundreds of your hard-earned dollars.

Environmental concerns

Disposable batteries contain harmful chemicals like nickel, lead and mercury that could pollute the environment. Rechargeable batteries also contain harmful elements but the reusability of these batteries prevents the frequent disposal of the same compared to that of disposable ones.

Longer lifespan, no maintenance, no gas emissions, deep lifecycles and less environmental impact definitely makes rechargeable batteries better than your old batteries.


These solar batteries are rated to deliver 5 kilo-watt hours kWh per cycle. Check your power bills to find the actual kWh consumption for your home or business. Find the average per day and the peak daily kWh consumption. We have solar battery packs available that provide power storage from 1kWh to more than 100 kWh.

What is a Kilo-Watt Hour?

A kilo-watt hour is a measure of 1,000 watts during one hour. The abbreviation for kilo-watt hour is kWh. So 1,000 watts during one hour is 1 kWh. The power company measures energy in kWh in order to calculate your monthly bill.

How Many kwh Do You Need for your house?

The average home uses 900 kWh per month, or 10,800 per year, according to the U.S. Energy Information Agency EIA. That means the average power required per day is 30 kWh. Now, when sizing a grid-tied solar battery system for daily usage, you will want a system that can deliver up to 30 kWh, or possibly more for peak usage days. However, if you also want the system to provide off-grid backup battery storage, then you will typically choose 3X to 5X the daily average, or 90 to 150 kWh. This should provide ample storage for complete system autonomy in case of an extended power outage of 3 to 5 days. Combine the battery storage with a PV solar panel system to ensure that you will have a renewable power source to keep the batteries charged.

    Keep in mind your grid-tied solar panels pack it in during a power outage. One battery will keep it up.
    Alternately, a generator will keep you solar panels up by telling the inverter the grid is up while cutting power to the grid. The Solar panels will power most of your house with the generator running you AC during the day, then taking over the whole house during the night.
