  "textContent": "The battery comprises a series of modules (2) each containing a single cell (3) connected across the output side of an individual charging unit (4). The cells are also series connected, through separable connector blocks (5), those at the extreme ends being connected (7) to the input side of a discharge controller (6). In the usual way, one such terminal is earthed (G). All the chargers are fed in parallel (40) from a common supply source (8), also connected (9C) to the regulator. Each charger includes an FET-based DC/DC converter and a limiter restricting the maximum current to a fraction, eg. 1/3, of the cell's Ah rating. The load is supplied via the regulator at a constant voltage, or, if acceptable, directly by the battery. Cell charging proceeds on a tapering basis to a predetermined threshold voltage, eg. 4.0v, which is then maintained, the charging current rapidly falling as the cell becomes charged. If the load draws current the current reversal is detected, and charging is interrupted.",
