Lithium Ion Battery - 12V 12Ah - With Protective Circuit Board- BSL12120
Battery Specialist Lithium Iron Phosphate (LiFePO4) batteries are designed for 2,000 Cycles at 100% DOD. These batteries offer a significant longer cycle Life and longer float/calendar life than lead acid batteries while helping to minimize replacement cost and reduce total cost of ownership.
LiFePO4 batteries delivers twice the power of lead acid batteries, even high discharge rate, while maintaining high energy capacity. Rest assured that Under/Over voltage and current protection ensures safe and efficient operation and are designed to work with AGM chargers.
Battery Specialist LiFePO4 batteries represent an advancement in safety due to cell design including various safeguards such as high temp thermal fuse,
flame retardant additive, and pressure relief valves.
With Battery Specialist LiFePO4 batteries you have a drop-in replacement of lead acid batteries. Modular design enables deployment of up to four batteries
in series and up to ten batteries in parallel.

Storage and Transportation
1. Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2. During transportation,50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.
3. Battery should be kept at -20℃～45℃ where it’s dry, clean and well-ventilated.
4. During loading of battery, attention must be paid against dropping, turning over and serious stacking.
Warnings & Tips
In order to prevent the battery leaking, getting hot and exploding, please pay attention to preventing measure as following:
Never throw the battery into water, keep it under dry, shady and cool circumstance when not use.
Never upside down the positive and negative.
Never connect the positive and negative of battery with
Never ship or store the battery together with metal
Never knock, throw or trample the battery.
Never cut through the battery with nail or other edge tool.
Never use or keep the battery under the high temperature. Otherwise it will cause battery heat, get into fire or lose some function and reduce the life. The proposed temperature for long-term storage is 10-45℃.
Never throw the battery into fire or heating machine to avoid fire, explosion and environment pollution; scrap battery should be returned to the supplier and handled by the recycle station.
Never use the battery under strong static and strong magnetic field, otherwise it will destroy the protecting device.
If battery leaked, the electrolyte get into eyes, please don’t knead, please wash eyes by water and send to hospital. Otherwise it will hurt eyes.
If battery emit peculiar smell, heating, distortion or appear any unconventionality during using, storage or charging process, please take it out from device or charge and stop using.
Never cut the battery in socket directly; please use the stated charger when charging.
Check the voltage of battery and relevant connectors before using the battery. It can’t be used until everything turns out to be normal.
Prior to charging, fully check the insulativity, physical condition and ageing status, since breakage and ageing are never allowed; the pack voltage must not be less than the cutoff voltage, if not, it’s abnormal and that battery needs to be labeled. The user should contact our Customer Service Dept and it can’t be charged until repaired by our staff.
The battery should be stored in 50% SOC. It needs to be charged once if out of use for as long as half a year.
Clean the dirty electrode, if any, with a clean dry cloth, or poor contact or operation failure may occur.
