48V 76Ah Lithium Battery
- Free Shipping to Lower 48 U.S. States
- In stock, ready to ship
Golf carts, home energy solutions, off-grid, and many more applications await this 48V 76Ah beast. Shed over 200 pounds of your golf cart and cruise endlessly with the latest in lithium cell technology. Or bundle a few of these together for days on end of off-grid electricity storage.
We engineer for durability and reliability too. Durability means operating in freezing temperatures all the way down to -4°F all the way up to 140°F. The built in BMS system protects against over charging, over discharging, over current and over heating.
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.
20.50" x 10.50" x 9.00"
|3000 cycles at 90% DoD
|Storage Discharge Rate
|~3% per month
|32°F to 115°F
|-4°F to 140°F
|Max Continuous Discharge
|Max Pulse Discharge
This combination works flawlessly. The Astro battery supplies the needed 125Amps at Maximum thrust as required by the motor manufacturer. My 1440 Alumacraft boat reaches 17.8 MPH and runs all day on one charge. (not at 17.8MPH) The battery charges quick and is ready to go again the next day if I needed it, Did I mention it's incredibly light ( about 59lbs?), and I can take it in and out of the boat with much effort. Totally satisfied
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.
Our 48V battery can only be operated in parallel mode. Up to 6 batteries can be tied together to create over 450 amp hours of capacity.
This model can not be operated in a series.
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.
Yes, but you will you need to add a converter. We recommend the Reliance 48V to 12V Golf Cart Voltage Reducer. This DC to DC converter will plug into our 48V battery and reduce the voltage down to 12V to run all the 12V accessories on your golf cart.
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!!!
