1.2.3 – Battery Management System (BMS)

The PHI 3.8 Batteries within the AccESS unit are manufactured utilizing Lithium Ferrous

Phosphate (LFP) cells, which are produced under exclusive patented licensed technologies, as well

as proprietary materials, architecture, manufacturing processes and battery management system

(BMS). This assures the highest grade and quality, longest cycle-life, greatest efficiency and

freedom from material impurities, toxicity and hazardous risk.

Each PHI 3.8 Battery within the AccESS unit contains circuitry that protects the Lithium Ferrous

Phosphate cells from overcharge, over-discharge and excessive load amperage. If the values

specified are exceeded, the protective circuitry will shut down the flow of electricity to/from the

PHI 3.8 Batteries. In some cases, this will result in the need to re-initialize an inverter charger.

Often, inverter system settings will be saved within the inverter memory storage and will not need

to be reset. This is not an absolute standard but is common amongst most inverter chargers and

should be anticipated if the PHI 3.8 Batteries go into a state of self-protection and shut down the

flow of electricity.

1.2.4 – PHI 3.8 Battery Connection Terminals

The PHI 3.8 Batteries are equipped with two 3/8’’ threaded studs with a lock washer and nut. The

red colored high temperature molded insert connection is for the positive lead. The black colored

high temperature insert connection is for the negative lead.

CAUTION: Do not attempt to loosen the large brass nut at the base of the terminals. This

will Void the Warranty.

CAUTION: Do not reverse polarity. It will Void the Warranty. Use a voltmeter to check

polarity before connecting terminals.

Water Resistant Cable Boots are also included and will be in place when your units arrive. The

boots are to be placed over the cable terminations and will stretch to form a water-resistant seal

around the base of the molded inserts and terminal connections.
