CAUTION: Verify polarity at all connections with a standard voltmeter before 1) energizing

the system and 2) turning the PHI 3.8 80 Amp breaker “ON/OFF” switch to the “ON”

position. Reverse polarity at the battery terminals will Void the Warranty and destroy the

PHI 3.8 Batteries.

PHI 3.8 Batteries pose some risk of shock or sparking during the installation and initial wiring and

connection process. This is consistent with all other battery-based storage formats. Be sure to turn the

built-in 80 Amp breaker to the “OFF” position to minimize the risk of shock or sparks during the installation

and commissioning of the system. Use of insulated gloves, clothing and footwear is always recommended

when working in close proximity to electrical devices. Cover, restrain or remove jewelry or conductive

objects (metal bracelets, rings, belt buckles, metal snaps, zippers, etc.) when working with any electrical or

mechanical device. Cover or restrain long hair and loose clothing when working with any electrical or

mechanical device.

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.
