Compared to SLA battery's 40-60% discharge, our lithium batteries can discharge 100%, extending the time between replacements, leading to significant cost savings. Higher energy density and many years of daily use from Dr.Prepare Lithium batteries. - 【Built-in 7A BMS Protection, Grade A+ Cells】Our lithium batteries feature a built-in BMS with six safeguards: high temperature, overcharge, over-discharge, overcurrent, short circuit, and auto balance protection. Coupled with IP56 water and dust resistance capabilities, it ensures durability in various conditions. Moreover, devoid of heavy and rare metals, our LiFePO4 batteries are environmentally friendly. - 【Series and Parallel Connection】Our lithium batteries support wiring in series to create a 24V/36V/48V 7Ah battery bank system. Additionally, they can be wired in parallel to build a 12V 16Ah/24Ah/32Ah system. Furthermore, you can connect up to 16 batteries in both series and parallel to construct a robust battery bank system with a total capacity of 1433.6Wh. Kindly note that ensure all batteries are fully charged individually before connecting in series. - 【Cut the Weight by 60%, No More Heavy Lifting】Dr.Prepare's 12 volt 7Ah lithium deep battery weighs only 1.98 lbs, equivalent to two 500ml water bottles. In contrast, a sealed lead-acid battery typically weighs around 6 to 7 lbs, resulting in a remarkable 60% reduction in weight. - 【Wide Applications】Dr.Prepare 12V 7Ah lithium battery is the perfect replacement for your less durable SLA batteries. It is suitable for a variety of applications, including fish finder, solar gate openers, solar water pump systems, home alarm systems, home security systems, amateur radios and more (Not a starter battery). - 【Kind Reminder】1. Use a compatible AC-to-DC LiFePO4 charger to charge the LiFePO4 battery type. Do not use general-purpose or lead-acid battery chargers. 2. It is F2 terminals, you should use a charger with crocodile clips, CANNOT fix with regular screws for charging. 3. Optimal charging current is 3A, with a max of 7A. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DZ281Z3C | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Battery Weight | 2.2 Pounds | | Best Sellers Rank | #58,054 in Health & Household ( See Top 100 in Health & Household ) #104 in 12V Batteries | | Brand | DR.PREPARE | | Built-In Media | 12V 7A LiFePO4 Battery | | Customer Reviews | 4.3 out of 5 stars 58 Reviews | | Item Weight | 2.2 Pounds | | Manufacturer | DR.PREPARE | | Model Name | 12V 7A LiFePO4 Battery | | Model Number | DBT12100LFP-S48 | | Number of Batteries | 1 12V batteries required.
