lithium batteries vs agm

The battery system is composed of high-performance power management module (BMS) to monitor and control the battery module, which has the protection functions of over discharge, over charge, over-current, short circuit, reverse connection and over temperature, making the battery safe and reliable.

Lithium batteries have the added bonus of not containing the heavier lead-acid found in AGM’s, therefore , are much lighter . Since their DOD is 80-90%, lithium a battery bank generally occupies less space.lithium batteries can save quite a bit of volume and weight in comparison to the traditional AGM’s.

Deep cycle/recycle lithium battery

We current main produce 18650/26650/21700/30700/4680 lithium ion cell and lithium iron phosphate cell,Lithium-ion batteries have a theoretical lifespan of about 800 cycles,and for lifepo4 cell,the cycle life around 1500-2000 times

The PCM main IC we used Japan Seiko IC,it has Over-charge,over-discharge,over-current and short-circuit Protection function.The PCM also can customized to your request,such as add PTC, NTC,and with cell balance function.


Finished battery usually it is with PCM.Wire, and connector,it used for Bluetooth speaker, led light,solar street light and other digital device.
