Are LG MJ1 cells protected?
No. These are unprotected flat-top cells. A properly engineered battery pack must use appropriate battery-management, overcharge, over-discharge, overcurrent, short-circuit and thermal protections.
Can ULS provide cells from the same production lot?
Same-lot coordination may be available for qualified quantities. Confirm the requirement before ordering because availability depends on current inventory and supplier allocation.
Is testing included with every order?
Standard orders do not automatically include individual capacity or DCIR testing. Screening, matching and cell-level data are available by written quotation.
How are bulk lithium cells shipped?
Lithium-ion cells are regulated for transportation. Shipping method, packaging, documentation, transit time and freight cost depend on quantity, destination and applicable carrier requirements.
