Discover LiTime's LiFePO4 battery chargers—safe, efficient, and optimized for lithium batteries. Fast charging, smart protection, and perfect for RVs, boats, and solar systems.
Choose the right LiFePO₄ battery charger by system voltage (12V / 24V / 36V / 48V), output current, and installation style—bench/portable or waterproof onboard. For RV, marine, and compact off-grid power, use the guide below to jump straight to the product pages that fit.
Note: These are navigation summaries. For exact charge curves, protections, wire gauge, and installation diagrams, please see each product page.
All chargers in this collection are optimized for LiFePO₄ charging profiles and include smart protections (over-voltage, short-circuit, temperature safeguards). If your system mixes chemistries (e.g., AGM/lead-acid), follow the mode guidance on the product page.
Round out your setup with DC-DC Chargers (alternator → house battery), Solar Charge Controllers (panel → battery), Inverters (DC → AC loads), and Battery Accessories (wiring & protection).
Do I need a special charger for LiFePO₄?
Yes. Use a charger with a LiFePO₄ profile to ensure correct cut-off and maintenance behavior that protects cycle life.
Onboard waterproof vs. bench charger—how do I pick?
Onboard waterproof suits RV/marine permanent installs and damp spaces; bench/portable fits shop charging and shared use across rigs.
When do multi-bank chargers make sense?
When you maintain separate 12V banks (starting, house, electronics), a 2/3/4-bank unit charges them independently in parallel.
Using a charger specifically designed for LiFePO4 batteries is critical for the safety, performance, and lifespan of your battery. Standard lead-acid chargers will damage your lithium battery.
Here’s why a dedicated LiFePO4 charger is essential:
To protect your investment and get the power you expect, always use a dedicated LiFePO4 charger.
Yes, absolutely. Our LiFePO4 batteries are designed to be safely and regularly charged to 100% of their capacity. Charging to full gives you access to the battery's maximum power and runtime.
Pro-Tip for Maximum Longevity: For users looking to achieve the absolute highest number of cycles over many years, you can optimize battery life by keeping the daily state of charge between 20% and 80%. However, this is not a requirement, and charging to 100% before a trip or for heavy use is perfectly fine.
It's best to avoid this. Your LiTime battery includes a built-in Battery Management System (BMS) that acts as a safety net, automatically shutting off the battery to prevent over-discharge damage.
However, relying on the BMS regularly can reduce the battery's long-term lifespan. For optimal health, the best practice is to recharge the battery when it reaches approximately 20% capacity.
For maximum safety and battery health, we recommend disconnecting the charger once the battery is fully charged.
While our smart chargers are designed to automatically stop charging when the battery is full, disconnecting it is the best practice and ensures you prevent any potential issues.
Yes, safety is a top priority. Our chargers are engineered with multiple, robust layers of protection to safeguard both you and your battery.
Standard Protections Include:
Special Feature: 0V Activation
Our chargers also include a 0V (Zero-Volt) Activation function. This unique feature can safely "wake up" and revive a LiFePO4 battery whose BMS has triggered a shutdown due to over-discharge. This can potentially save a battery that other chargers would be unable to recognize or recharge.
Yes, you can charge your battery bank with a single charger, but the method is different for each configuration.
⚠️ Critical Rule for Both Setups: Always start with identical batteries (same brand, capacity, and age [within 1 month]) and ensure they are at the same voltage level before connecting them for the first time.
Charging in Series (e.g., two 12V batteries to make 24V)
Use the Right Charger: You must use a charger that matches the total combined voltage. For a 24V system, use a 24V LiFePO4 charger.
Balance Regularly: To prevent damage and ensure longevity, you must disconnect the batteries every few months and charge each one individually with a 12V charger. This re-balances the bank.
Charging in Parallel (e.g., two 12V batteries to make a larger capacity 12V bank)
Use the Right Charger: Use a charger that matches the single battery voltage. For a 12V parallel bank, use a 12V LiFePO4 charger. It's also recommended using a bus bar when charging batteries connected in parallel.
Connect for Even Charging: For the best results, connect the charger's positive lead to the first battery and the negative lead to the last battery in the bank. This helps the entire bank charge more evenly.
The short answer is: it depends on your charging setup.
If you usually take your battery off the boat to charge it—such as in a garage, workshop, or at home—a standard charger is a safe and economical choice. This approach keeps the charger away from moisture and works well for many boaters.
However, if you prefer the convenience of charging your battery while it’s on the boat, a waterproof charger is a must. Installing a charger directly onboard—especially in compartments exposed to splashes, rain, or high humidity—requires a model that can withstand wet conditions. A waterproof charger not only improves safety but also ensures reliable performance and a longer service life.
To make the right choice, consider your charging habits:
Many of our battery packages come with a standard charger to offer great value for typical use. But if you're setting up a permanent onboard charging system, we strongly recommend choosing an IP65-rated waterproof marine charger for dependable, weather-resistant performance.
