A cell unit 10 has a cell 2 and associated electronic circuit board 12 carrying for example charge/discharge control circuitry or temperature monitoring circuitry. The cell may be a lithium ion cell and comprises a casing 8 with projecting terminals 8. The circuit board as at least two openings 20, with connection tabs 22 of the control circuitry extending into each opening. The connection terminals 8 and tabs 22 overly and are connected to one another. The openings allow access to both sides of each tab such that a welding operation may be used to make the connection. The tabs are stated to still be within the outer envelope of the cell such that no folding of the tabs is required to ensure that the circuit board remains close to the cell. |
