Combine the best batteries with the best chargers. This 24v 10 AMP charger will charge our 24v 50Ah battery from 0% to 100% charge in about 5 hours. We design our chargers specifically for LFP batteries to ensure the longest life cycle of your battery. Sealed Lead Acid battery chargers will reduce the life and performance of our batteries.

Easy to Use

Each charger has an LED indicator to show when the battery is fully charged. Red means the battery is charging, Green means the battery is fully charged. 

Also, our chargers use alligator clips to ensure compatibility with a wide variety of battery terminals. 

Why use Lithium Chargers?

Standard lead acid batteries operate at a maximum voltage of about 12.7 volts. As a result, many standard chargers will only charge to this voltage. Our lithium batteries operate at a maximum voltage of 14.4 volts. This means standard chargers will not charge lithium batteries to full capacity. Depending on the lead acid charger, it may only charge to 60% to 80% of the batteries fully capacity.

In most cases, orders will ship within 1 business day.

8 Year "No Gimmicks" Warranty

To learn why we call our warranty a "No Gimmicks" Warranty, check out this article.

Astro Lithium warrants its batteries against defects in materials or workmanship for eight (8) years from the original date of manufacture, with a minimum 70% retention of Battery capacity over the warranty period. All other products such as chargers and accessories come with a one (1) warranty.

  • During the product warranty period, Astro Lithium will credit, replace, or repair the product if the product is deemed to be defective in materials or workmanship. 
  • This warranty extends only to products distributed and/or sold by Astro Lithium to the original purchaser only. Warranties are non-transferable.
  • This warranty does not cover misuse, neglect, accidental damage, improper installation, or normal wear and tear.
  • This warranty does not cover disasters such as, but not limited to, fire, flood, lightning, improper electric current, or acts of God.
  • Astro Lithium is not responsible for loss of data, time or hardware failure besides our products. Astro Lithium is not responsible any loss work ("down time") caused by a product requiring service.
  • For a battery to be exchanged under warranty, the Astro Lithium manufactured serial number must be present on the battery. Removal of this date code will void the warranty. 
  • This warranty and all agreements shall be governed by and interpreted in accordance with the laws of Florida.


30 Day Money Back Guarantee

Any feelings of skepticism you might have about investing in an LFP battery is completely normal! This is why Astro Lithium makes every effort to absorb as much risk as possible so you're free to make a good decision. We want to make it easy for you to prove that our batteries are quality products backed by quality support.

We want you as our customer to be 100% satisfied. Astro Lithium guarantees you a 30-Day Return window (beginning the date of receipt) to evaluate your purchase.

Within the thirty (30) days, and for any reason, you may exercise your right to return or exchange your purchase. A refund or exchange will be issued once the battery has been returned and all items are accounted for. Returned items are subject to a ten percent (10%) restocking fee.



If you have the proper charger, charging lithium batteries is no different than most other battery types. Any charger from us, or any charger with an AGM Charging profile will work perfect. Standard lead acid battery chargers will not allow you to maximize the performance of lithium batteries. Due to their lower operating voltage, a standard lead acid battery charger may only charge your Astro Lithium battery to 60% to 80% of its full potential. We strongly recommend a LiFePO4 rated charger to get the most out of your batteries.

All of our batteries are shipped FREE to the Lower 48 United States. All products ship via UPS Ground.

To determine the charge time on your battery, take the total amp hour (Ah) rating and divide it by the amp rating of the charger.

For example: when using a 10AMP charger, a 54 Ah battery would take about 5.4 hours to charge from 0% to 100%.

Our chargers have an LED indicator built-in.

RED = Charging

GREEN = Fully Charged

LFP batteries are very safe. When we hear about lithium battery fires, those are related to other Lithium-Ion battery chemistries. Our batteries are Lithium Iron Phosphate and use a different chemistry that is much more stable.

Lithium iron phosphate has excellent thermal and chemical stability. These batteries stay cool in higher temperatures. They are also incombustible when mishandled during rapid charges and discharges or when there are short circuit issues. Lithium iron phosphate does not experience thermal runaway in the same way that other lithium-ion batteries do, as the phosphate cathode will not burn or explode during overcharging or overheating as the battery remains cool.

Extensive testing has shown that the ideal charge rate for lithium batteries is 1/3rd or less of the battery amp hour rating. So if you have a 54 Ah battery, we recommend using an 18 amp charger or less.

Our batteries are capable of faster charging but this may affect the long term performance of the battery when done excessively.
