This device is completed with a lithium-ion polymer 3.6V 65Ah, and this battery is mainly used in energy storage and EVs. Its maximum charging current is 21.6A and the maximum discharge current is 32.5A. the battery may experience this voltage on an infrequent basis, when the battery`s voltage reaches this line, the charging power shall be reduced to zero. Unless otherwise specified, “Reference charge” shall consist of charging at a constant current of 21.6V, to 4.05V and 13.0V to 4.2V. the charging current is tapering after the cell voltage gets 4.2V to 3.25V. for test purposes, charging shall be performed at 25±2℃.

“Reference discharge” shall consist of discharging at a constant current of 32.5A to 2.5V, discharging shall be performed at 25±2℃ unless otherwise noted (such as temperature-dependent capacity test).

Reference performance test: cells shall be charged by reference charge to 4.2V and discharged to 2.5V. cells shall be rested for 60 minutes after both charge and discharge.

Reference cycle test: cells shall be charged by reference charge to maximum voltage level and discharged to minimum voltage level. The maximum and minimum voltage level is determined by test purpose. Cells shall be rested for 60 minutes after both charging and discharging.

So this battery is very professional and used for outdoor transmitters. As an energy storage device battery.
