PHI 3.8 Batteries do not vent any harmful gasses, and do not require special ventilation or cooling.

PHI 3.8 Batteries are not capable of thermal runaway. As with any battery, if the cells are severely

damaged due to physical abuse incurred outside of warranted specifications, it can cause electrolyte

leakage and other failures. The electrolyte can be ignited by an open flame. However, unlike other lithium

ion batteries (e.g. LCO, NCM, and NCA), the PHI 3.8 Batteries’ electrolyte and other material components

generate a limited amount of heat and do not propagate fires.

1.2.2 – Charging at Temperatures Below Freezing

It is important to take necessary steps to determine the temperature of the PHI 3.8 Battery prior to

charging the battery, as the battery may otherwise be adversely impacted.

CAUTION:

Do not attempt to charge the PHI 3.8 Battery below 32° F (0° C). Although cold temperatures

do not harm PHI 3.8 Batteries, attempts to charge at subfreezing temperatures can adversely affect SOH

and cycle life, and will void the Warranty. If the PHI 3.8 Battery must be charged below 32° F (0° C), the

rate of charge must be at no more than 5% of the PHI 3.8 Battery’s rated capacity (C/20).

CAUTION: Only use a SimpliPhi approved LFP charger if ancillary charging is required before installation,

testing or troubleshooting. Failure to use a SimpliPhi approved LFP charger will damage the PHI 3.8 Battery

and void the Warranty. Refer to the PHI 3.8 Manual for details regarding SimpliPhi-approved ancillary

charging equipment.

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 volt meter 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.
