Description
【Longer Lifetime, Lower Costs】 Dr.Prepare 12V 20Ah LiFePO4 batteries offer over 4,000 cycles, surpassing the 300-500 cycles of lead acid batteries. 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 10 years of daily use from Dr.Prepare Lithium batteries.
【Built-in 20A BMS Protection, 10-Year Warranty】 Our lithium batteries feature a built-in BMS with 6 safe protections: high-temperature, low-temperature, over-charge, over-discharge, over-current, and short circuit. 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.
【Cut the Weight by 60%, No More Heavy Lifting】 Dr.Prepare 12 volt 20Ah lithium 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.
【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, home alarm systems, home security systems, ham radios, and more (Not a starter battery).
【Kind Reminder】 To charge Power Wheels, you need to connect the Wire Harness Connector with Dr.Prepare 12V 20Ah LiFePO4 batteries. Wire Harness Connector NOT INCLUDED.

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?
Yes, the built-in BMS works with a low temp sensor to provide complete low temperature protection. When the temperature reaches 23℉ to 41℉ (-5℃ to 5℃), this lithium battery will stop being charged, and then the temperature reaches -13℉ to 5℉ (-25℃ to -15℃), the battery will stop discharging.
Can I wire these batteries in series and in parallel?
Yes, Dr.Prepare 12V 20Ah 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 10V.
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 to charge 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℃.

Backup battery for radios
I bought this battery to use with my hf radio in the field. Next week I’ll do what I call a stress test to see how long it will actually last. For now I already know it doesn’t compare with another battery I have (even though it’s larger in size as well as amp hours).

8Ah LifePo batteries for various uses sealed
Needed a couple of batteries in this form factor for my two UPS units (one for the computer/cable and one for the TV). The battery is a Lithium Iron Polymer battery which hold their charge better and last longer than the NiCd batteries they replaced. Installation was easy, same battery size and shape as the dead ones.4000 cycle rated so it should last a long time.
