FAQs
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.
Golf cart batteries are shipped via LTL Freight.
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.
