• 【100% Grade A BMS Protection】Highest level of safety Based on the UL test report of Grade A batteries in the battery and upgraded BMS, our LiFePO4 battery has a built-in 100A BMS to prevent overcharging, over-discharging, overcurrent, overheating and short circuit, with excellent self-discharge rate, ensuring the safety level of LiFePO4 batteries and optimizing 12V battery performance.
• 【15000 Cycles, 10-year Life】Our LiFePO4 lithium battery has higher energy density, more stable performance and greater power. Our lithium iron phosphate (LiFePO4) battery can be cycled 4000 times (100% DOD) to 15000 times (60% DOD), with a service life of up to 10 years. (Warm Tips: If the battery is not used continuously, it should be charged every 3-5 months, which can make the battery last longer)
• 【Lightweight and Easy to Carry】Our 12V 100Ah LiFePO4 battery weighs 24.2 pounds, which is only 1/3 of the weight of the lead-acid battery of the same capacity, which is lighter and easier for you to move or carry. And our LiFePO4 battery is fully charged faster and more convenient to use. If you buy more 12V 100Ah lithium batteries and add a waterproof box, it is perfect for ships, boats and trolling motors, making your outdoor fishing and sea parties more fun.
• 【Expand to 48V 100AH/12V 400AH】4-pack-12V100Ah battery connection tips: 1. To connect in series or parallel, the batteries need to meet the following conditions: First - the same battery capacity (Ah); Second - from the same brand; Third - before connecting in series or parallel, please fully charge the battery individually (resistance voltage＞13.4V); 2. Series limit: up to 4 identical batteries, up to 48V (51.2V) 100AH; 3. Parallel limit: up to 4 identical batteries, up to 12V 400Ah.
• 【Versatile Use of Lithium Batteries】Our 12V 100Ah Lithium batteries support series and parallel connection for greater capacity, ideal for marine, trolling motors, boats, RVs, electric vehicles, recreational vehicles, golf carts, solar energy, kayak vehicles, lighting, backup power, home energy storage, off-grid applications, etc.
• 【Reminders before Using】 1. When you receive 3-4 batteries, fully charge them separately and connect them in parallel for 1-2 hours. Make them reach a voltage balance state. 2. To meet the series connection requirements, please use a thicker connecting wire.
• 【1-4 Working Day Delivery】 DJLBERMPW has a local warehouse in the United States, and the delivery time is 1-4 working days. Our online service provides 24-hour fast feedback. If you have any questions, please feel free to contact us and we will provide timely assistance.
• Important Tips:
  • 1. If new battery cannot be charged after use, it may enter over-discharge low voltage protection and need to be activated.
  • 2. We recommend our 12V20A lithium charger with activation function, which can reduce many usage problems. It can also charge multiple batteries at the same time, just the batteries in parallel.
  • 3. Before connecting multiple batteries in series, the voltage must be balanced first, and the voltage difference of each battery not exceed 0.1V.
  • 4. Please contact us first if you have any questions. We will actively communicate, check the problems and provide after-sales support.
