Lithiumate™ Cell Boards for large cylindrical cells

Standard Cell Boards matched to large Li-Ion cells

One Cell Board per 2 cells in series (and 1 to many in parallel) Cell Board (green in picture) is mounted to the top terminals of 2 side-by-side adjacent cells A single wire (blue in picture) connects the Cell Board and the opposite ends of the 2 cells Reliable mechanical mounting and direct electrical connection A single communication wire is used between adjacent cells boards in a bank

Possible bank arrangements:

Number of cells in the bank	Cell boards
	Mid-bank*	Positive	Negative
3	0	1	1*
4	0	1	1
5	1	1	1*
6	1	1	1
7	2	1	1*
8	2	1	1
9	3	1	1*
10	3	1	1
11	4	1	1*
12	4	1	1
13	5	1	1*
14	5	1	1
15	6	1	1*
16	6	1	1

For N cells, where N is even, you need n/2-2 "mid-bank" cell boards, and only 1/2 of the negative board is used
For N cells, where N is odd, you need (n+1)/2-2 "mid-bank" cell boards

• Right angle connectors are standard on end boards. Versions with straight connectors or without connectors are available with quick turnaround
  • With right angle connectors - requires no extra mounting space beyond the cell bolts
  • With straight connectors - requires some extra mounting space beyond the cell bolts
  • Without connectors (cables to the BMS controller are soldered directly to the cell board) - requires no extra space beyond the cell bolts
• Part number: 1LC0060M:
  • 1 = Cell Board
  • LC = Large cylindrical
  • 0060 = 60 mm cell diameter (available: 40, 60 mm)
  • M = mid bank (available: P, M, N)

Parts in bold are stocked. Versions without connectors or with straight connectors are available.

See the wiring instructions.

Power connections:

• Connection to the mid-point between the 2 cells is through the ring terminal on the yellow wire
• Connection to the positive terminal of the most positive of the 2 cells is through the ring terminal on the red wire
• Connection to the negative terminal of the most negative of the 2 cells is through the ring terminal on PCB

Signal connections:

• Signal connection between adjacent cell boards is through the gray and orange wires
• Signal connection to the BMS controller is through two 2-pin connectors, one to the positive end board (red and black wires) and one to the negative end board (white and green wires)

Common specifications:

Item	Label	Nom
PCB Width	W	1.2" / 30.5 mm
PCB Length	L	1.6" / 40.6 mm
PCB thickness	t	0.062" / 1.6 mm
Overall height, no connector	H1	0.3" / 7.5 mm
Overall height, w/ right angle connector	H3	0.47" / 12 mm

Right angle connector is standard on positive and negative end cell boards. Mid-bank cell boards do not have a connector.
