A battery charging system comprises a battery charger, a first battery 14a, a second battery 14b connected in series with the first battery, and first and second voltage regulation circuits 16a, 16b. The battery charger provides a charging output to the series-connected and second batteries. The first voltage regulation circuit is connected in parallel with the first battery and provides a first conductive current path that bypasses the first battery in response to a voltage across the first battery exceeding a threshold value. A second voltage regulation circuit is connected in parallel with the second battery and provides a second conductive current path that bypasses the second battery in response to a voltage across the second battery exceeding a threshold value. |
