Battery Management System
Every Astro Lithium battery has on board Battery Management System, also known as a BMS.
The main functions of the Astro Lithium BMS are as follows:
Cell balancing: Our BMS ensures that all the cells within a battery pack are balanced and charged equally. This helps to prevent overcharging or undercharging of individual cells, which can cause performance issues or even damage to the battery.
Charge control: Our BMS regulates the charging process to ensure that the battery is charged within safe limits. This helps to prevent overcharging, which can cause overheating and damage to the battery.
Discharge control: The BMS regulates the discharge process to prevent the battery from being discharged beyond safe limits. This helps to prevent damage to the battery and extends its lifespan.
Temperature control: The BMS monitors the temperature of the battery and regulates the charging and discharging processes to ensure that the battery operates within safe temperature limits. This helps to prevent overheating, which can cause performance issues and damage to the battery.
State of charge (SOC) and state of health (SOH) monitoring: Our BMS monitors the SOC and SOH of the battery to provide information on the battery's capacity and health. This helps to prevent overcharging, undercharging, and other issues that can damage the battery and shorten its lifespan.

My 36v 100ah Battery was replaced at no charge including shipping
And replacement is great
Thanks Capt. Ron
Battery performance is incredible! Customer service is top notch.
Love the Battery it works perfectly for my trolling motor. Also the customer service is second to none. I have had nothing but a great experience with Astro Lithium and would recommend them to anyone!
Purchased the 36 Volt 100 ah battery to replace 3 lead acid batteries. I have used it multiple times and has always performed as it should. The customer service is excellent with calling with questions prior to my purchase. Wish I had the Bluetooth monitoring like the new version but I have gone 3 days of fishing with out a charge and have not had a problem.
24 hours of run time on trolling motor and still only at 60% capacity. I only got 6 hours of run time on three 12 volt deep cycle lead acid batteries. Huge difference.
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.
