Description Specification Downloads FAQ Dr.Prepare 12V 20Ah Lithium Battery, Built-in BMS, 4000+ Cycles LiFePO4 Battery, for Fish Finder, UPS, Radio, Power Wheels, Electric Scooters, Lighting, Ride on Toys, Home Security System Dr.Prepare’s 12V 20Ah lithium batteries, backed by a 10-year warranty and service life, are the optimal choice for replacing less durable sealed lead-acid batteries. Notably, our lithium batteries offer extended assurance compared to competitors. With LiFePO4 technology, they support 100% discharging, ensuring longer usage compared to SLA batteries, which can only output 40-60% of their power capacity. Additionally, the lightweight design, at only 1/3 of SLA weight, significantly reduces the burden when carrying it for outdoor backup power. Upgrade to Dr.Prepare for enduring reliability and efficiency. Description 【Longer Lifetime, Lower Costs】 Dr.Prepare’s 12V 20Ah LiFePO4 batteries offer over 4,000 cycles, surpassing the 300-500 cycles of lead acid batteries. With the ability to discharge 100% compared to SLA’s 40-60%, our lithium batteries extend the time between replacements, leading to significant savings. Expect 10 years of daily use from our batteries. 【Cut the Weight by 60%, No More Heavy Lifting 】 Dr.Prepare’s 12V 20Ah lithium battery weighs a mere 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. 【Built-in BMS Protection】 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 batteries are environmentally friendly. 【Series and Parallel Connection 】 Our lithium batteries support wiring in series to create a 24V/36V/48V 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. Ensure all batteries are fully charged before connecting in series. 【Wide Applications】 Our 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, power wheels, electric scooters, UPS backup power systems, solar gate openers, solar water pump systems, home alarm systems, home security systems, amateur radios, ride-on toys, and more (Not a starter battery). 【Important Reminders】 1. For powering your lawn mower, connect 4 batteries in series (48V system). 2. Ensure all batteries are fully charged before connecting in series. 3. Use a lithium battery-compatible charger for charging. 4. Dr. Prepare batteries will be shipped from California, USA. We provide 10-year battery warranty and lifetime technical support, if you have any questions during usage, please feel free to contact us.

Download Is it a motorcycle starter battery? No, it is NOT a starter battery. Our battery is a deep cycle Lithium Iron Phosphate (LiFePO4) Battery, with a maximum power output of 20Ah. Does this battery have low temperature protection? No, these 12V 20Ah lithium batteries lack low-temperature protection. However, their built-in BMS includes safeguards such as high temperature, overcharge, over-discharge, overcurrent, short circuit, and auto balance protection. Can I wire these batteries in series and in parallel? Yes, Dr. Prepare lithium batteries support both series and parallel connections. Please use identical batteries for the connection. For optimal performance, follow these guidelines: 1. Ensure all batteries are fully charged before connecting. 2. Use interconnect cables of the same wire gauge (AWG) and length from the same brand to maintain consistent impedance, preventing unbalanced charge and discharge performance. 3. Connect batteries one by one in series (up to 4 batteries) or parallel (up to 4 batteries). Securely tighten all cable connections between the lugs and terminals. Does this battery have low voltage cut-off protection? Yes, it does. The battery will automatically shut off when the discharge voltage drops below 11.1V. What are the charging voltage and charging current for this battery? The recommended charging parameters are as follows: adjust the voltage to 14.2V and use a 10A charger for optimal performance. While the maximum charging voltage is 14.6V and the maximum charging current is 20A, adhering to these specified values will enhance the charging efficiency of the batteries. Can I use my lead acid battery charger to charge the lithium battery? We recommend using a lithium battery-compatible AC to DC charger for charging our LiFePO4 batteries to avoid causing irreversible damage to their lifespan. Additionally, these batteries can be charged using compatible solar charge controllers and solar panels. How to properly store this battery? We recommend maintaining the battery at 100% state of charge or, at the very least, 30%-50% state of charge. Disconnect the battery from any load by removing the terminal cables. It’s highly advisable to charge the battery every 6 months during periods of non-use to prevent over-discharge. For storage lasting 1-3 months, keep the battery in an environment with a temperature range of -4℉ to 113℉ / -20℃ to 45℃. For longer storage periods, particularly up to 1 year, it is recommended to store it in an environment with a temperature range of -4℉ to 68℉ / -20℃ to 20℃. More questions about this product?
