batteries
I have no industry experience on battery systems, but to increase the energy efficiency to above 80% or 90%, the power must be decreased less than 64% or 36% of the stated maximum output power value (again using the same theorem). However, the internal resistance will vary with several operating parameters, so my numbers are for an ideal case.

Peukert''s law
OverviewFire safetyBatteriesFormulaExplanationLimitationsExternal links
Peukert''s law brings a certain degree of fire-safety to many battery designs. It limits the maximum output power of the battery. For example, starting a car is safe even if the lead–acid battery dies. The primary fire hazard with lead–acid batteries occurs during over-charging when hydrogen gas is produced. This danger is easily controlled by limiting the available charge voltage, and ensuring ventilation is present during charging to vent any excess hydrogen gas. A secondary danger exi…
Maximum power/current for a battery?
The maximum power output of a battery decreases as the temperature decreases. This is because the chemical reactions within the battery slow down in colder temperatures, reducing the amount of energy that can be delivered per unit of time. On the other hand, high temperatures can also damage a battery and decrease its overall maximum …
