About Tycorun 12 Volt 18Ah Lithium Deep Cycle Battery

A-product lithium battery cells

We always insist on using A-product lithium battery cells as the core part of lithium batteries. Because it is different from other products, high-quality lithium batteries can ensure the safety of users. Lithium batteries are recognized as dangerous goods by international organizations. Only by using brand new materials can the batteries serve us safely. This is why we highly recommend 12V 18Ah lithium batteries. Quality is always our pursuit.

Intelligent BMS protection system

As the most important part of the lithium-ion battery, the quality of the protection board determines whether the battery can be used safely. As we all know, lithium is a very active element. In order to prevent the imaginary appearance of lithium batteries from overcharging, overdischarging, and heat generation, we have introduced a BMS protection system. This is an intelligent system that can protect the battery according to our settings. In general, our 12V18Ah lithium battery provides six kinds of protection to our users. They are overcharge protection, overdischarge protection, high temperature protection, overcurrent protection, short circuit protection, and low voltage protection.

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
