12V miniature regenerative lithium iron phosphate battery, lightweight and portable, endless energy storage.

The bright LCD display can be added as an extra, as bright as a mirror lake, reflecting the vagaries of battery voltage and capacity in real time. She is crafted from high quality lithium iron phosphate, as solid as a rock, safe and reliable.

She has a long life course, a distant 10 to 15 years ahead, like the tailor of time, sewing long sleeves for life. She has stepped up to replace heavy-duty lead-acid (AGM / GEL) batteries, and despite weighing only one-third as much as the original, her capacity has not diminished a bit.

Her cycle life is as instantaneous as a star, 2000 cycles @ 100% DOD, 6000 cycles @ 50% DOD, and the light of day melts into infinite years in her memory, demonstrating amazing durability. Just like the flow of notes, the extension of charging time and the improvement of service life, she is economical, environmentally friendly, and she is the companion dancer of time.

She is equipped with many talents and is able to cope with both series and parallel connections. Like a flexible dancer, she has a built-in BMS and carries multiple safety protections, so that no matter how the wind rises, she can remain stable.

Electric power field: power tools, robots, AGV, vacuum cleaner, electric sprayer, remote control car, etc.
Consumer electronics: Bluetooth speakers, speakers, LEDs and various electronic devices, etc.
Energy storage: communication base station, data center, home energy storage, wind power storage, photovoltaic power generation, etc.
Special fields: medical equipment, security power supply, special equipment, etc.

3、Can I use 12V 12Ah battery instead of 12V 7ah battery?
Yes, you can replace a 7ah battery with a 12ah battery as long as the physical size and voltage requirements meet your needs.
Generally speaking, for the same battery material, the larger the capacity, the larger the size. So as long as the dimensions are the same, a 12v 12ah is a replacement for a 12v 7ah and can support longer run times.

4、Why does my battery discharge itself?
Batteries are electrochemical devices, which means that electricity is stored and discharged through chemical reactions that occur inside the battery.
When your battery is not in use, some chemical reactions still occur, but on a much smaller scale. As a result, your battery's capacity slowly decreases over time. This is called self-discharge.
The self-discharge rate of a battery depends on the battery technology, lifetime, and storage temperature.
Typically, deep cycle AGM and GEL batteries self-discharge between 2% and 15% per month at 68°F. However, the self-discharge rate doubles with every 15°F increase.
Lithium batteries, such as LFP (LiFePO 4 ), have monthly self-discharge rates as low as 0.35% to 2.5%.
