In a series battery connection, the voltages add together, and the current (amp-hour capacity) remains the same. For example, two 12V 100Ah HBOWA LiFePO₄ batteries wired in series will output 24V at 100Ah.
While the individual batteries may have slight differences in charge levels, balancing ensures that each battery discharges and charges evenly. This prevents overcharging or deep discharging, which can damage the batteries and reduce their lifespan.
$280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
