Description

  • Low Temp Cut-Off Protection】 Low temperature cut-off protection can maintain a healthy battery lifetime. When the temp reaches 23℉~41℉, this lithium battery will stop being charged, and when the temp reaches -13℉~5℉, the battery will stop discharging. Ideal for harsh and rugged environments.
  • Series and Parallel Connection】 Whether creating a 48V lithium ion battery bank or a 12V 400Ah power system, our Dr.Prepare LiFePO4 batteries are both supported. You can even wire up to 16 batteries in series and parallel to build a powerful home battery bank system with a power of 20.48 kWh. 
  • Improved Active BMS Protection】 Optimized circuit can handle cell balancing, over-current cutoff, over-charge cutoff, over-discharge cutoff, high and low temperature cutoff, and short circuit protection for increased performance and longer lifetime.
  • 3,000 Lifespan, 10-Year Lifetime】 Up to 80% capacity for 3,000 cycles in recommended conditions, while the typical sealed lead-acid batteries have only 500 cycles. Provides roughly a 10-year lifetime of daily use.
  • 2-3 Times More Power】 Dr.Prepare 12V LiFePO4 batteries provide a maximum of 1,280 Wh power output, which is 2 to 3 times more powerful than typical SLA batteries of the same size. 100A max continuous discharge current powers most electrical devices. Monitor the remaining power capacity via the built-in LED display.

Last Longer

Dr.Prepare lithium batteries provide roughly 6 times longer life than typical sealed lead-acid batteries, and they still provide 80% of rated capacity after 3,000 cycles.

Intelligent BMS

The built-in improved Battery Management System (BMS) ensures a longer lifetime and safer handling compared to lead-acid batteries that do not have BMS. 

Built for the Outdoors

Robust shell with IP65-rated dust and water resistance enables the battery to maintain stable performance even in extreme environments. Fearless of any rain or splashes.

No More Guesswork

The built-in LED screen allows you to monitor real-time battery capacity with ease.
Note: Turn off all electrical appliances before checking the current battery capacity. 

Package Includes 

● 1 x 12V 100Ah Lithium Iron Phosphate (LiFePO4) Battery with Handheld Strap
● 1 x M8 Bolts (A Pair)

Important Notes:
1. Make sure to tightly screw the battery terminals in, as having loose battery terminals will cause the terminals to build up heat resulting in damage to the battery.
2. When the battery is fully discharged at a continuous 100A, it cannot be recharged at 50A immediately, which will trigger high temperature charging protection.
3. It's highly recommended to charge the lithium ion battery with 20A current. The maximum charging current is 50A, and exceeding this current will shorten the battery's lifespan.
4. Turn off all electrical appliances before checking the current battery capacity.

How long will this battery last?
 
Our lithium ion batteries enable more than 3,000 charge and discharge cycles at 80% DOD (Depth of Discharge), which allows for around a 10-year lifetime of daily use.
Does this battery have low temperature protection?
 
Yes, the improved BMS works with a low temp sensor to provide complete low temperature protection. When the temp reaches 23℉~41℉ / -5℃~5℃, this lithium battery will stop being charged, and when the temp reaches -13℉~5℉ / -25℃~-15℃, the battery will stop discharging.
What data can I view from the LED screen?
 
You can view the remaining battery capacity and battery voltage from the LED screen. For monitoring more precise data, we recommend turning off all electrical appliances before checking for current battery capacity.
Can I wire these batteries in series and in parallel?
 
Yes, these Dr.Prepare lithium batteries support series and parallel connection. Please note that you need to use identical batteries to connect.
For optimal performance, we kindly advise you to follow the requirements listed below to connect your batteries together:
1. Fully charge all ready-to-connect batteries.
2. All battery interconnect cables should be the same wire gauge (AWG) and length, and come from the same brand. Otherwise, the impedance will be inconsistent, resulting in unbalanced charge and discharge performance.
3. Connect your batteries one by one in series (up to 4 batteries) or in parallel (up to 4 batteries). Tightly screw all cable connections between the cable lugs and terminals.
Does this battery have low voltage cut-off protection?
 
Yes, it does. When the discharge voltage is lower than 11.1V, the battery will shut off automatically.
What are the charging voltage and charging current for this battery?
 
The maximum charging voltage is 14.6V and the maximum charging current is 50A. For optimal charging performance, we highly recommend adjusting the voltage to 14.2V and using a 20A charger.
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, or else cause unreversible lifespan damage to the batteries. You can also charge these batteries using compatible solar charge controllers and solar panels.
How to properly store this battery?
 
We recommend keeping the battery at 100% state of charge, or at least 30%-50% state of charge. Then disconnect the battery from any load by removing the terminal cables. Highly recommend charging the battery every 6 months when not in use to prevent over-discharge.
When storing the battery for 1-3 months, you can place it in an environment with a temperature range of -4℉~113℉ / -20℃~45℃; when storing it for 1 year, it is recommended to place it in an environment with a temperature range of -4℉~68℉ / -20℃~20℃.
