About Tycorun 12 Volt 50Ah Lithium Deep Cycle Battery

High-current discharge of lithium batteries may be the direction of future research. For lithium batteries, we can’t just limit ourselves to energy storage, but more importantly, they can support high current discharge. Astronaut’s 12V 50Ah lithium battery supports 50A discharge, which can support the use of most low-power loads. Charging with a current of 10A allows the battery to be fully charged in just 5 hours. When we take a break at night, we connect the power supply to charge, and when we wake up the next day, the battery will be fully charged and continue to serve us. Compared with lead-acid batteries, the use environment of lithium batteries is more relaxed. Of course, we can also use a higher current 50A charge according to the situation, and the battery can be fully charged in 1 hour, but this will damage the battery.

 Compared with lead-acid batteries, lithium batteries can provide greater energy density, which is unmatched by lead-acid batteries. Energy density refers to the amount of energy released per unit weight. The energy density of LiFePO4 lithium battery reaches 260wh/g, which means that for the same weight of lithium battery and lead-acid battery, the electric energy released by lead-acid battery is only 1/5 of that of lithium battery. For sophisticated instruments, choosing a lithium battery is the best choice.

1.How safe are Lithium Ion Batteries?

Our LiFePo4 batteries are considered to be safe, non-flammable and non-hazardous by international and federally regulated standards.

2.What can I use a Lithium Battery for?

Our Batteries are commonly used for marine, RV and golf cart applications. You can use our lithium batteries for any application that would normally use a single or multiple lead acid, GEL or AGM batteries.

3.How do I change my batteries to Lithium?

After you take out your old batteries, place our batteries in the same way. You can use the same cables to reconnect into the Lithium Battery.

4.How do I charge a Lithium battery?

Our lithium ion technology uses the latest and most advanced built-in battery protection system to prevent damage to the battery. You may utilize a standard charger for our products, although in some cases a lithium charger may be required to charge the batteries.

5.What battery do I need for my RV or Camper Van?

The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the 12v 100Ah battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine’s alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteri



Ventilators are widely used during the epidemic. For people who are dying, ventilators are the most important epidemic to save lives. But have you ever thought about it. When the mains power is interrupted, without the support of direct current, the ventilator will lose its function. Therefore, the lithium battery can provide backup power for the ventilator. In an emergency, the high current discharge of the lithium battery can easily drive the ventilator and provide stable energy for a long time.


3D printer is one of the most successful inventions of modern technology. No matter how crazy the idea is, 3D printer can help you realize it. For precision instruments, it is necessary to ensure its normal power supply. The promotion of lithium batteries provides stable energy for 3D printers. As backup power, lithium batteries have been silently protecting your equipment behind the scenes.
