Our smallest battery, the Astro Lithium 12v 12Ah Lithium Battery is small enough to fit in the palm of your hand, but do not let that fool you. This little battery still produces a punch, enough to charge your smartphone from 0% to 100% about 30 times.
Every Astro Lithium battery has on board Battery Management System, also known as a BMS. The BMS protects the battery from the following situations:
The BMS also performs the following functions.
6" x 4" x 4"
|Cycle Life||3000 cycles at 90% DoD|
|Storage Discharge Rate||~3% per month|
|Charging Temperature||32°F to 115°F|
|Operating Temperature||-4°F to 140°F|
|Max Continuous Discharge||12A|
|Max Pulse Discharge||30A|
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.
No. This battery does not have the high cranking amps required to start a boat or car engine. This battery is for deep cycle applicaitons such as operating trolling motors, golf carts, marine electronics, and many more.

Yes, our batteries are great for operating in series or parallel applications.
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.
While our voltages vary slightly, they are completely fine to work with 12 volt, 24 volt and 36 volt applications.
The variation stems from the nominal voltage of an LiFePO4 cell being 3.2 volts. When assembled in packs, the closest multiples become 12.8 volts, 25.6 volts and 38.4 volts. These voltages are well within the operating limits of 12v, 24v and 36v equipment.
Have had 36 volt for over 8 months with incredible performance. Can not believe how little batter discharges after 10 hrs on the water.
We are extremely happy with our 36V lithium battery. It is an excellent product.
Thank you for standing behind your product and replacing the original charger with one that works very well. Great job of customer service !
My 36v 100ah Battery was replaced at no charge including shipping
And replacement is great
Thanks Capt. Ron
Easy to use and works great for Astro lithium and batteries are top notch!!!
