PHI 3.5 Batteries do not vent any harmful gasses, and do not require special ventilation or cooling.
PHI 3.5 Batteries are not capable of thermal runaway. If the cells are severely damaged due to physical
abuse incurred outside of warranted specifications, which can cause electrolyte leakage and other
failures, as with any PHI 3.5 Battery, the electrolyte can be ignited by an open flame. However, unlike
other lithium ion batteries (LCO) there are no hazardous or toxic materials in the electrolyte or the
material components of PHI 3.5 Batteries. See PHI 3.5 Installation Manual for details.
1.2.2 – Charging at Temperatures Below Freezing
It is important to take necessary steps to determine the temperature of the PHI 3.5 Battery prior to
charging the battery, as the battery may otherwise be adversely impacted.
CAUTION:
Do not attempt to charge the PHI 3.5 Battery below 32° F (0° C). Although cold
temperatures do not harm PHI 3.5 Batteries, attempts to charge at subfreezing temperatures can
adversely affect SOH and cycle life, and will void the Warranty. If the PHI 3.5 Battery must be
charged below 32° F (0° C), the rate of charge must be at no more than 5% of the PHI 3.5
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 3.5 Battery and void the Warranty.
1.2.3 – Battery Management System (BMS)
The PHI 3.5 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, assembly methods 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 3.5 Battery within the AccESS unit contains circuitry that protects the Lithium Ferrous
Phosphate cells from overcharge, over-discharge and extreme load amperage. If the values
specified are exceeded, the protective circuitry will shut down the flow of electricity to/from the
PHI 3.5 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 3.5 Batteries go into a state of self-protection and shut down the
flow of electricity. Refer to SimpliPhi’s inverter integration guides for inverter charge controller
settings or contact the inverter manufacturer.
1.2.4 – PHI 3.5 Battery Connection Terminals
The PHI 3.5 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.
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.
