SYLJ Was Verified by TÜV Rhineland and Made in China & Offering Class A and 100% Authentic Cells

Why Lithium? Our batteries utilize lithium iron phosphate technology, the safest and most stable chemistry on the market.Our lithium batteries offer a longer life expectancy of 3,000 to 5,000 deep discharge cycles compared to about 200 life cycles from a standard lead-acid battery. At almost a fifth of the weight of your standard lead-acid, you have the capability to deplete these batteries to 0% without damaging the batteries, you can double the power you are currently receiving. Our batteries are as safe as they get, and do not emit any fumes or gas, making storing inside an option for customers. Having a built BMS (battery management system), will protect your batteries from short circuit, low/high voltage disconnect and low/high temperatures. These batteries are backed up by our customer service that will exceed any other battery company you have worked with before.

About The Easy To Install BMS Smart App
BLUETOOTH PHONE INTERFACEfor displaying battery information on your phone! 12V Lithium batteries can also be connected two in parallel to double the Amphours or two in series to make 24V. The built-in DALY Battery Management System is easily accessible via a phone APP.
In the App you will be able to monitor and check the battery's current state of charge, current voltage, current cycles status and temperatures, individual cell voltages and the minimum and maximum voltages.
The BMS provides temperature sensors (for prismatic cells and BMS itself) protecting against over-charging, over-discharge and short-circuiting and also amplifies the battery lifespan. The no memory effect means this battery can be charged and used at any time in any condition, so no need to discharge the battery before charging.
