Why choose a pre assembled battery pack? Higher Safety & Reliability Professionally assembled with certified welding, balanced cells, reliable BMS and full insulation, effectively avoiding short circuits, fire risks and poor connections. AGING TESTING BEFORE SHIPPING, KEEP THE POWER STABLE AND ALL OF CELLS SAME VOLTGAE, INNER RESISTANCE. Ready to Use, No Hassle No need to source cells, cases, wires or tools. Simply install and power on, saving time on assembly, testing and troubleshooting. Stable & Consistent Performance Cells are carefully matched for voltage, internal resistance and capacity. Finished packs offer longer cycle life and more stable discharge than DIY. Certified & Transport Compliant Finished packs come with specifications, safety certifications and shipping documents, making them legal for export, logistics and commercial use. Time saving Buy a pre assembled battery pack: plug and play, do DIY to build your battery pack which need about 3-4 Hours for a unit. AGING TESTING Benefits of Battery Pack Aging Filter out defective cells early Reduce failure rate and improve reliability. Balance voltage and performance Make the battery pack more stable and consistent. Fully activate battery capacity Bring the pack to its best working condition. Test BMS and safety performance Avoid hidden dangers in actual use. Extend service life Reduce later attenuation and ensure longer cycle life. For the battery pack purchase, what factors will be your most concern? 1.Battery cells, which is the core of the battery pack, and cost much in whole energy storage system. we use EVE 334AH, which is the most popular model in whole market. 8000 times cycle life, based EVE auzthorization. All of cells have matched: capacity, inner resistance and voltage. 2. BMS, which is another important core for whole energy storage system. BMS function: over charge, over discharge, short circut protection, over voltage, over current and communication with inverter , to monitor the battery parameters better. The battery pack use JK V19 BMS, 16S 200A: BP2A16S20P, with 2A active balancer. jk bms are combine most of main stream inverters. Such as Deye, Growatt, Victron and others. For now, we have Poland warehouse for battery cells, box and battery pack. Support ship to EU address or pick up from Poland warehouse. About shipping: shipping by truck, door to door, tax free, shipping time about 7-10 days. About warranty: 10 years+ wholelife tech support. For battery cells, quality problem will send to you the problem to replace it, for the BMS died, then send to you a new BMS as replacement.
