Review: New battery, not old stock! - First full charge then discharge to 10.5v with a fast bounce back to 11v. I'm happy so far. This was a 2 amp rate and it held extremely steady till the end. A heavier test will be next. Before I run the second 20 amp hour battery test though I have fantastic results from the hundred amp hour battery that I also purchased! I had to baby my tester as much as I could to pull enough juice out of it in a reasonable amount of time but I managed to get 99.12 amp hours and roughly 9 hours 57 minutes at about an 8-10 amp draw rate. I'll admit these are the very first charge and discharge tests on these batteries that I've received within days of this post but I will continue to test and I will update on each of these batteries if anything changes for the worse. So far though $120 for $100 amp hours and $46 for 20 amp hours is a pretty good deal!
Review: Very Good Deal For Great Powerful Battery. - This big battery that cost around a dollar per amp, not per watt. I have use it for running my small microwave over as 100% off grid. This battery has came in almost dead, that has taken so long while to charge it with 20 amp charger. If you use it on average electric car, that will give you around 10 to 12 miles range. At first I had saw Dr Prepair, at first; I thought it Dr. Pepper HA-HA. After I had saw from Will's on YouTube, as he is is impressed of the built quality. This single battery is so great for trolling motor for you boat with 3 times longer run time that much heavier lead acid battery. You will getting around 1 extra MPH of speed.

## Features

- [Coulomb Tech Meter] In 2025, updated with advanced coulomb technology, this meter maintains ≤5% error accuracy. Its digital screen displays the discharging current and voltage in the discharge state, the remaining capacity and voltage in standby mode, and the charging current and voltage in the charging state. Unlike voltage-based meters (which show only battery bars with 30-40% inaccuracy, and only shows battery voltage with level bars.), DR.PREPARE meter provides exact numerical data.
- [Grade A+ Cells & Built-in BMS with Low Temperature Cut-off] Our Dr.Prepare 100Ah LiFePO4 battery with monitor screen offers a 10-year product support and lifespan. The advanced built-in BMS system provides 20+ layers of protection — including low- and high-temperature cut-off — to protect the battery during charging and discharging, even under extreme conditions. Plus, all internal battery Grade A+ cells are UL-tested to ensure maximum safety and reliability.
- [Upgrade to Dr.Prepare LiFePO4 Batteries] Dr.Prepare lithium batteries outperform traditional lead-acid batteries with a longer lifespan of up to 10 years, compared to just 1–3 years for most SLA options. Weighing only 22 lbs, this 12V LiFePO4 battery is lighter and delivers more consistent power than standard SLA batteries. Plus, it features an integrated BMS for enhanced safety — a level of protection SLA batteries simply don’t offer.
- [5,000 Cycles, 10-Year Lifespan] DR. PREPARE LiFePO4 battery has 5,000 cycles at 60% deep discharge and 3,000 cycles at 80% deep discharge, providing about a 10-year lifetime, while only 500 cycles for the sealed lead-acid batteries. The 12V rechargeable LiFePO4 battery provides a maximum of 1,280Wh power output, which is 2 to 3 times more powerful than SLA batteries of the same size.
- [Series & Parallel Connections for Powerful Backup Power] Dr.Prepare 12V 100Ah lithium battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V battery bank with series wiring, or expand your capacity to 12V 200Ah, 300Ah, or 400Ah through parallel connections. For larger setups, you can link up to 16 batteries in series and parallel to create a powerful 20.48 kWh home backup system—ideal for power outages or hurricane season.
- [Trolling Motor, Marine, Boat, Solar, RV] When using the battery with a trolling motor, we highly recommend installing a 60A–100A circuit breaker between the battery and your device to prevent overdischarging. 60A circuit breaker sold separately in the Dr.Prepare Store. These LiFePO4 batteries are also perfect for Marine, Boat, RV, camper, solar setups, off-grid, camping, fish finder and home backup power during outages or hurricane season.
- [Charging & Discharging Tips] The optimal charging current is 20A (max 50A). For safe and efficient charging, use a compatible AC-to-DC LiFePO4 battery charger or a solar panel system with a charge controller. Do not use other brand general-purpose chargers to avoid potential damage. Each battery must be fully charged separately before in series. After a full discharge at 100A, avoid immediate recharging at 50A, as it may trigger the high-temperature charging protection.
- [Important Reminders] 1. It's an energy storage battery, not a car battery, starting battery or golf cart battery. 2. Ensure the battery terminals are securely fastened. Loose terminals can lead to heat accumulation and potential battery damage. 3. Optimal charging involves a 20A current for our lithium battery. While the maximum charging current stands at 50A, exceeding this limit can result in a shortened battery lifespan.
