Description

  • 【10-Year Service Life】 Dr.Prepare's 12V lithium batteries are accompanied by a 10-year product assurance and service life, a substantial improvement compared to lead-acid batteries which typically offer lifespans of only 1 to 3 years. It's the perfect choice for replacing lead-acid batteries, providing long-lasting durability.
  • 【Low-Temperature Cut-Off Protection】 The low-temperature cut-off protection ensures the longevity of the battery's health. When the temperature falls within the range of 23℉ to 41℉, the charging process halts. Similarly, when the temperature drops between -13℉ to 5℉, discharging ceases. This feature makes it ideal for use in challenging and demanding environments.
  • 【Series and Parallel Connectivity】 Our LiFePO4 batteries support series and parallel connections, allowing you to create a 12V, 24V, 36V, or 48V battery bank, or 12V 200Ah, 300Ah, or 400Ah power system. You can even connect up to 16 batteries in series and parallel, building a powerful home backup power system with a 20.48 kWh capacity. 
  • 【2-3 Times More Power】 Dr.Prepare 12 volt lithium batteries offer an impressive power output of 1,280 Wh, surpassing conventional lead-acid batteries of similar size by 2 to 3 times. With a maximum continuous discharge current of 100A, these batteries can power most electronic devices. Monitor the remaining power capacity and battery voltage via the built-in LED screen. 
  • 【Improved BMS Protection】 Our upgraded internal BMS expertly manages cell balance, over-current, over-charge, over-discharge, temperature extremes, and short circuits. This refinement leads to enhanced performance and prolonged lifespan. Plus, IP65 dust and water resistance ensures reliable functionality.
  • 【Important Reminders】
  • 1. Ensure the battery terminals are securely fastened. Loose terminals can lead to heat accumulation and potential battery damage.
  • 2. After a full discharge at a continuous 100A, avoid immediate recharging at 50A, as this may trigger high-temperature charging protection.
  • 3. Optimal charging involves a 20A current for our lithium-ion battery. While the maximum charging current stands at 50A, exceeding this limit can result in a shortened battery lifesp
  • 4. Turn off all electrical appliances before checking the current battery capacity.
  • 5. 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.

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 power 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℃.

These batteries are phenomenal!

I bought the one with the Max hub first. That one is awesome. Then I ordered a group 31 battery and that one was flawless too. I ordered 3 more of the group 31 and charged and discharged those and no issues. I am ready to put 4 31 batteries and charge them with solar. I am now ready in case I end up without power for 10 days again. I hope not, but I’m prepared with Dr. Prepare batteries!

Shipping misshape

Ordered battery received wrong tracking number. Battery didn’t come to me but several states away. Contacted company and they apologized and checked into it and sent a new tracking number and I received my battery! Shipping is a little slow but they worked through the issue and I received my battery. It came with a 13.13 volts I’m impressed with the looks and appearance of quality. I will put it to use and report back. They are a safe company to order from and will be ordering again. I gave 4 stars just for slower time receiving!

Works so far, Time will tell.

I purchased 3 of these. All 3 have the digital indicator and all have issues. 2 don't show state of charge and 1 does not show charge rate either. They offered to replace them. I chose to keep them. This does not effect rhe operation of the batteries. Only a visual indicator. They perform as described. Take a full charge and provide full discharge. Time will tell if they hold up.
