Huge power for big applications. Our biggest battery for the most demanding applications. The 36v 100Ah Astro Lithium Battery will handle whatever you need for nonstop adventures. Run trolling motors for days with this behemoth energy storage solution.
Not only does this battery pack a huge punch, but it comes in a small package considering how much you are getting. This 36v battery will save your rig over 200lbs compared to traditional lead acid batteries with the same performance.
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"
|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||100A|
|Max Pulse Discharge||200A|
Shipping is free on all batteries and chargers. All products are shipped via UPS Ground. Due to federal regulations, we cannot ship batteries overnight.
In most cases, orders will ship within 1 business day.
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. All other products such as chargers and accessories come with a one (1) warranty.
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.
Our batteries are have been tested to be compatible with all major trolling motor brands such as Rhodan, Minn Kota, Motor Guide, Garmin, Lowrance and more.
For information on which battery to consider for your trolling motors thrust rating, check out our blog post here.
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.
Our 36 volt batteries can be run in parellel, but they cannot be run in series. Only our 12 and 24 volt batteries can be operated in series connection.
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.
These lithium batteries are the real deal. I replaced my old lead acid batteries with these and I wish I had done it years ago. Night and day difference in performance.
Should have done this a lot sooner. Highly recommend Astro Lithium. I almost went with Dakota, but chose Astro due to the ultra competitive pricing, and top notch customer service.
Very helpful with answering questions during the sales process. I’m very happy with them so far.
Out of this world performance. I use these batteries for my boat flounder gigging all through the night and they haven't failed me yet.
