\ud83d\udd0b THE ULTIMATE GUIDE TO LITHIUM BATTERY STORAGE:<\/h1>\n

Understanding Depth of Discharge (DoD) & The True Cost Per Cycle<\/h3>\n

When selling Dyness Lithium Batteries, customers often only look at the Upfront Price<\/b> and Total Capacity<\/b>. But the true measure of a battery\u2019s value is its Cost per kWh per Cycle<\/b> (Levelized Cost of Storage).<\/p>\n

This brochure breaks down exactly how Depth of Discharge (DoD) impacts battery life, and proves mathematically why larger batteries are the smartest long-term investment for Pakistani homes.<\/p>\n

\n

\ud83d\udcc9 PART 1: What is Depth of Discharge (DoD)?<\/h2>\n

Depth of Discharge (DoD)<\/b> refers to the percentage of the battery’s total capacity that you actually use before recharging it.<\/p>\n

Think of a lithium battery like a fuel tank:<\/p>\n

    \n
  • 100% DoD:<\/b> You drain the battery to absolute zero. (Highly stressful, damages the battery’s chemical health over time).<\/li>\n
  • 80% DoD:<\/b> You use 80% of the battery and leave a 20% “buffer” at the bottom. (The industry standard for daily solar use).<\/li>\n
  • 50% DoD:<\/b> You only use half the battery before recharging. (Very gentle, drastically extends the battery’s lifespan).<\/li>\n<\/ul>\n

    \u2696\ufe0f The Golden Rule of Lithium Batteries (The Trade-Off)<\/h3>\n

    There is a direct tug-of-war between Daily Usable Backup<\/b> and Total Lifespan (Cycles)<\/b>:<\/p>\n

      \n
    1. Shallower Discharge (e.g., 50% DoD):<\/b> The battery experiences less stress, so it will last for more cycles<\/i> (more years). However, you get less usable backup power<\/i> per day.<\/li>\n
    2. Deeper Discharge (e.g., 80% DoD):<\/b> You get maximum daily backup<\/i> during loadshedding, but the battery experiences more stress, resulting in fewer total cycles<\/i> over its lifetime.<\/li>\n<\/ol>\n
      \n

      \ud83e\uddee PART 2: Calculating the “Cost Per kWh Per Cycle”<\/h2>\n

      To find out how much it actually costs to store and use one unit (kWh) of solar energy, we use this formula:<\/p>\n

      Total Selling Price \u00f7 (Capacity \u00d7 DoD \u00d7 Expected Karachi Cycles) = Cost per Unit\/Cycle<\/b><\/p><\/blockquote>\n

      Note: The “Expected Karachi Cycles” below are heat-adjusted. Lab tests assume a perfect 25\u00b0C. In Pakistan’s ~35\u00b0C+ indoor environments, cycle life is realistically adjusted to 4,000 cycles (for 6k-rated models) and 5,500 cycles (for 8k-rated models) at 80% DoD.<\/i><\/p>\n

      \ud83d\udcca Step 1: Expected Lifespan (Cycles) by DoD<\/h3>\n

      Because shallower discharges reduce stress, the battery survives more cycles.<\/p>\n\n\n\n\n\n\n

      \ud83d\udca1 PART 3: How to Read This Data (The Sales Pitch)<\/h2>\n

      1. The “Karachi Sweet Spot” is 60% to 80% DoD<\/h3>\n

      While 50% DoD offers the cheapest per-cycle<\/i> cost, it requires the customer to buy double the battery capacity just to get the same daily backup. If you can get along with 50% DOD and do not need long duration storage or have a generator backup in case you really need long duration power then this is better for battery life and reducing costs of electricity via storage.<\/p>\n

      60% to 80% DoD<\/b> is the perfect balance for many Pakistani homes. It provides enough backup to survive 4-6 hours of loadshedding while keeping the battery healthy for 10+ years. This is provided that the storage size is based on 4 to 5 hours of usage capacity.<\/p>\n

      If you run air conditioners on the inverter, and do not want to be bothered to worry about depth of discharge, then set the DOD to 50% and use an auto start generator beyond that.<\/p>\n

      2. The Ultimate Upsell: Bigger Battery = Cheaper Electricity!<\/h3>\n

      Look closely at the 80% DoD<\/b> column.<\/p>\n

        \n
      • A customer using the 5kWh<\/b> battery is paying Rs 17.39<\/b> in battery wear-and-tear for every 1 unit (kWh) of solar power they store and use.<\/li>\n
      • A customer using the 16kWh<\/b> battery is paying only Rs 9.17<\/b> for that exact same 1 unit of power.<\/li>\n<\/ul>\n

        The larger battery is almost HALF the price to operate per cycle!<\/b> Because the 16kWh uses larger, higher-capacity cells (like 280Ah\/314Ah) and undergoes less relative stress per cycle, its lifetime energy throughput is massively superior.<\/p>\n

        3. The Utility Comparison (The Closer)<\/h3>\n

        With K-Electric and WAPDA grid rates frequently crossing Rs 40 to Rs 60+ per kWh<\/b> (including taxes, peak-hour rates, and fuel adjustments), storing solar power in a Dyness battery is a massive money-maker.<\/p>\n

          \n
        • WAPDA Cost:<\/b> Rs 45.00 \/ unit<\/li>\n
        • Dyness 16kWh Storage Cost:<\/b> Rs 9.17 \/ unit<\/li>\n
        • Customer Savings:<\/b> Rs 35.83 per unit, every single day, for the next decade.<\/b><\/li>\n<\/ul>\n

          TAWANAI ENERGY Explanation for customers<\/h2>\n

          Many people just look at the upfront price of a 5kWh vs a 16kWh battery and think the smaller one is cheaper. But let’s look at the math for Karachi.<\/p><\/blockquote>\n

          If you buy the 5kWh battery, every time you store and use 1 unit of solar energy during loadshedding, it costs you about Rs 17.39<\/b> in battery degradation. But if you step up to the 16kWh PowerBrick, that same 1 unit of energy only costs you Rs 9.17<\/b>. You are literally buying electricity at half the wear-and-tear cost! Plus, the utility is charging you Rs 45+ per unit. By installing the larger Dyness bank with Tawanai Energy, you aren’t just buying a battery; you are locking in a Rs 9 per unit electricity rate for the next 10 to 15 years.<\/p><\/blockquote>\n

          You can also set the small battery to 50% DOD and get the cost per cycle down to about PKR 13.<\/p><\/blockquote>\n
