Description
WelsonPower offers both NCM (Nickel Cobalt Manganese) and LFP (Lithium Iron Phosphate) battery cells. Our NCM cells, commonly known as 18650 cells, come in four models: 1800mAh, 2000mAh, 2200mAh, and 2600mAh.
For our LFP cells, we provide three main types: cylindrical cells, prismatic cells, and pouch cells. Our cylindrical LFP cells include two models: the cylindrical 6Ah WSP-32700-6Ah and the cylindrical 15Ah WSP-321400-15Ah.
Our prismatic LFP cells are our flagship product series, with capacities ranging from 30Ah, 50Ah, 100Ah, 110Ah, 150Ah, 165Ah, to the largest 280Ah.
In addition, we offer LFP pouch cells in several models, including 20Ah, 25Ah, 30Ah, 40Ah, and 50Ah.
We are continuously developing new products in various sizes and capacities. We welcome all module and pack manufacturers to consult with us for their specific needs.

Discharging Curve
Stud Terminal:
All standard batteries are shipped without stud terminals, but we do offer the option of separate stud terminals at an additional cost to the customer. The customer purchases the separate stud terminals and then welds the studs to the cell themselves using laser welding equipment.
we could provide two type poles of these cells
first is prismatic battery positive and negative poles with 2-M4 terminal, hole depth 6.5mm, thread depth over 5.7mm(without Screws Terminal)
The second model comes with external studs already shipped from the factory.
