## Description

DR.PREPARE 12V 20Ah LiFePO4 Lithium Battery with Grade A+ Cells, 4000+ Deep Cycle Lithium Iron Phosphate Rechargeable Battery with 20A BMS for Fish Finder, Solar, Lighting, Alarm System

## Features

- 【Built-in 20A 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.
- 【Longer Lifetime, Lower Costs】Dr.Prepare12V 20Ah LiFePO4 batteries offer over 4,000 cycles, surpassing the 300-500 cycles of lead acid batteries. Compared to SLA's 40-60% discharge, our lithium batteries are able to discharge 100%, extending the time between replacements, leading to significant cost savings.
- 【Series and Parallel Connection】Our lithium batteries support wiring in series to create a 24V/36V/48V 20Ah battery bank system. Additionally, they can be wired in parallel to build a 12V 40Ah/60Ah/80Ah 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 4.096 kWh. 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 20Ah lithium deep battery weighs only 5.95 lbs, equivalent to five 500ml water bottles. In comparison, a sealed lead-acid battery typically weighs around 20 lbs, resulting in a remarkable 60% reduction in weight.
- 【Wide Applications】Dr.Prepare 12V 20Ah lithium battery is the perfect replacement for your less durable SLA batteries. It is suitable for a variety of applications, including fish finders, small UPS backup power systems ( each battery rated power =256W, 2 Batteries in Series for UPS ＜500W, 4 Batteries in Series for UPS＜1000W), solar gate openers, solar water pump systems, home alarm systems, home security systems, amateur radios, outdoor camping, etc (Not a starter battery).
- 【Kind Reminder】1. Use a compatible AC-to-DC LiFePO4 charger to charge the LiFePO4 battery type with crocodile clips. Do not use general-purpose or lead-acid battery chargers. Optimal charging current is 10A, with a max of 20A.
