Thank you for choosing TOPBAND Battery!

 

Our lithium iron phosphate battery pack TB-1220F 12V 20AH is the perfect replacement from GEL,LEAD ACID battery.

TB-1220F is designed as a "drop in replacement" meaning all you have to do is take our your old lead acid battery and place our battery in the same way.

 

TOPBAND lithium batteries are the ideal battery for any application that currently uses as AGM,GEL or lead acid battery.TOPBAND batteries give you the chance to replace your old obsolete battery storage system with the perfect battery for your application.

 

As you may know, Your existing lead based batteries are inefficient, obsolete and a problem waiting to happen.

Typical Lead Acid Batteries have many problems including: they loose up to 30% of their energy per month from self discharging. They have a severe voltage drop when a load is placed on them, they can off-gas, leak acid and hazardous chemicals, do not last long, they are very heavy and made of a toxic material. 

TOPBAND Lithium Ion Batteries are 99.9% efficient, Provide over 100% usable energy of the rated capacity,

and loose less than 3% per month self discharge

 

Whether you are installing a new Solar System, replacing your Marine Boat Batteries or outfitting a commercial application, TOPBAND Lithium ion Batteries give you the chance to do energy storage right from day one. Most Important for you are the facts that LiFePO4 Batteries can last for the duration of most applications, meaning you buy a TOPBAND battery once and you are done. And considering their longevity and the efficiently they are less costly than the heavy and toxic lead acid batteries.
