exponent,
A Peukert calculator is available at

Please note that Peukert's formula is no more than a rough approximation
of reality, and that at very high currents, batteries will give even less
capacity than predicted from a fixed exponent.
We recommend not to change the default value in the BMV, except in
case of Li-ion batteries: See section 6.
5.2 Midpoint voltage monitoring
Wiring diagram: see the quick installation sheet. Fig 5-12
One bad cell or one bad battery can destroy a large, expensive battery
bank.
A short circuit or high internal leakage current in one cell for example will
result in under charge of that cell and over charge of the other cells.
Similarly, one bad battery in a 24V or 48V bank of several series/parallel
connected 12V batteries can destroy the whole bank.
Moreover, when new cells or batteries are connected in series, they
should all have the same initial state-of-charge. Small differences will be
ironed out during absorption or equalise charging, but large differences
will result in damage during charging due to excessive gassing of the
cells or batteries with the highest initial state-of-charge.
