and battery failure. The relationship between maximum charging voltage and the number of cells in the battery is also significant. This will determine (for a given ambient temperature and state of charge) the rate at which energy is absorbed as heat within the battery. For lead-acid batteries, the voltage per cell must not ex-ceed 2.35 volts.
Lead acid batteries drawn considerably below 50% state of charge are subject to freezing, which will swell or split the battery case, destroying the battery. LiFePO4 batteries can be drawn down to 20% SOC, some say much lower, without causing damage or reducing the lifespan of the battery.
