True dc system protection and redundancy

Using a Best Battery Selector (BBS) is an effective and low cost method of providng true battery system protection and reduncy. When two or more batteries are paralleled, electrical isolation is required so that system redundancy is not compromised.
The BBS is a power diode arrangement that uses multiple parallel battery circuits while ensuring that no single battery will ever be a burden on the system.

The operation of lead acid batteries results in the electrolysis of water. Electrolysis reduces the amount of water in the electrolyte, which in turn requires the battery to be watered more frequently, increasing maintenance requirements. Hydrogen and oxygen are also naturally created as part of this process and these gases can accumulate and become explosive.

The Exponential Power recombination vent caps help to prevent the gases generated through electrolysis from escaping. Inside the cap is a catalyst (rare earth element) which reacts with hydrogen and oxygen and converts the gases into water vapor. This is an exothermic process and heat is generated during this recombination process.

As the battery stops gassing and the cap cools, water vapor condenses on the walls of the plug and will flow back into the battery, thus 98% of the hydrogen/oxygen gas mixture generated during charging will be recombined and converted back to water. This process effectively eliminates the flow of gases from the battery into the atmosphere.

Exponential Power recombination vent caps significantly improve safety, preventing (under normal conditions) the flow of gas into the immediate surroundings and eliminating the risk of ignition, as well as reducing the need for water refilling.
