Smaller Size, Same Power. Backed by a 10-Year Warranty

This Dr.Prepare mini-sized 12V 100Ah deep cycle LiFePO4 battery features a 30% smaller footprint than Group 24—perfect for tight spaces while saving room for what matters.

Packed with Grade A+ lithium cells and an intelligent BMS with 20+ protections, including low/high temperature cut-off, this lithium battery delivers up to 100A continuous discharge current while ensuring safe, stable performance in any environment.

Offering the same power in a more compact, lightweight form, it's the perfect upgrade from bulky sealed lead-acid batteries - without sacrificing capacity or lifespan. Backed by a 10-year service life, it's ideal for powering trolling motors, RVs, marine setups, solar energy systems, and more.

 

Description

  • 【Much Smaller Size, Same Power】 The Dr.Prepare 12V 100Ah LiFePO4 battery is engineered to be much more compact, saving approx 52% of installation space compared with Group 31 and about 36% compared with Group 24. It’s the perfect fit for tight compartments and mobile energy applications.
  • 【20+ BMS Protections, Grade A+ Cells, 10-Year Lifespan】 Built with Grade A+ high energy density cells and a smart BMS offering 20+ layers of protection - including low/high temperature cut-off - this deep cycle LiFePO4 battery delivers up to 100A continuous discharge current while maintaining safe and stable performance in a wide range of environments. It’s designed to last, with a 10-year lifespan and reliable product support for long-term peace of mind.
  • 【Perfect Replacement for Lead-Acid Batteries】Dr.Prepare 12V 100Ah LiFePO4 battery is an ideal upgrade from traditional sealed lead-acid (SLA) batteries. Weighing just 22 lbs, it’s up to 47% smaller and 70% lighter, while offering twice the usable capacity. With a 10-year lifespan- compared to just 1-3 years for most SLA batteries - it significantly reduces replacement frequency and long-term costs. Plus, it supports side mounting, giving you more flexibility in installation.
  • 【Safe Charging & Discharging】 Use a compatible AC-to-DC LiFePO4 charger or a solar panel system with a charge controller set to the LiFePO4 battery type. Do not use general-purpose or lead-acid battery chargers. Recommended charging current: 20A (Max: 50A). Maximum continuous discharge current: 100A. After a full 100A discharge, avoid immediately recharging at 50A, as it may trigger the battery’s high-temp charging protection.
  • 【Series & Parallel Connections】 Dr.Prepare LiFePO4 battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V system using series connections. Expand capacity to 12V 200Ah, 300Ah, or 400Ah with parallel connections. Supports up to 16 batteries in a combined series-parallel setup, ideal for home backup systems. For any configuration, all connected batteries must be the same model. NOT suitable for use as a car starter battery or for cranking boat engines.

What’s the dimension of a group 24 battery?
"The Group 24 battery is a standard size measuring 10.5″L × 6.1875″W × 8.875″H, commonly used in vehicles, backup power systems, and medical equipment. Our battery features a more compact design at 9.0″L × 5.4″W × 8.2″H. "
Can it be used in cold weather?
Yes — the Dr.Prepare 12V 100Ah LiFePO4 battery is equipped with low-temperature cut-off protection.

Charging cut-off range: 23℉~32℉ (-5℃ ~ 0℃)
Discharging cut-off range: -4℉~5℉ (-20℃ ~ -15℃)

The battery will automatically resume operation once the temperature rises above the cut-off point, helping to prevent damage in extreme cold conditions.
Can I use my sealed lead-acid battery charger to charge this LiFePO4 battery?
No, you can’t. Using a sealed lead-acid (SLA) charger may cause irreversible damage to the battery. You must use a compatible LiFePO4 (lithium iron phosphate) AC-to-DC charger.

If you’re using a solar off-grid system, you can charge the battery with solar panels and a charge controller that supports LiFePO4 batteries. Make sure to set the controller to the LiFePO4 battery type and configure the correct charging voltage.
Does this battery have low voltage cut-off protection?
Yes, it does. The battery will automatically shut off when the discharge voltage drops below 9.2V to protect against over-discharge. It will recover once the voltage rises above 11V.

If the battery enters low voltage protection mode, follow these steps to restore it:
1. Disconnect all wiring.
2. Use a LiFePO4-compatible charger or solar charge controller with an activation function.
3. Make sure the ambient temperature is above 32℉ (0℃) and charge the battery until the voltage exceeds 11V.
Will the battery come with terminals? And if not, what size are the connector terminals?
Yes, the battery comes with a pair of M8 × 16mm terminals and a pair of M8 × 12mm terminals.
Can I charge the battery directly using a solar panel?
No, you can’t. When charging this battery with a solar panel, you must use a solar charge controller (either PWM or MPPT) between the panel and the battery. Directly connecting the panel to the battery can lead to unstable power output, which may damage the battery or connected devices.
Can this battery be used as a starter battery?
No, it can’t. This battery is designed for low to moderate continuous power applications that require stable energy storage and delivery, such as RVs, off-grid solar systems, and home energy storage.

It is not suitable for applications that require high starting currents or power surges, such as engine cranking for cars or boats, or use in golf carts.
Can I connect this battery with my old Dr.Prepare batteries?
We do not recommend connecting this battery with older Dr.Prepare batteries. For both series and parallel connections, all batteries should be the same model, from the same brand, and ideally purchased at the same time.

Even slight differences in BMS (Battery Management System) settings between models can lead to performance issues or potential damage.
