CAUTION: Do not tighten the stud terminals beyond their specified torque value of 160 in-
lbs. Using an impact driver or power tools on the terminals will Violate the terms of the
Warranty. Using power tools or impact drivers may damage the terminal even if it doesn’t
result in breakage.

4.6 – Electrical Wiring
CAUTION: All SimpliPHI Batteries are designed to serve at fixed voltages and cannot be wired
in series to increase the battery bank’s voltage. Wiring the SimpliPHI Batteries in series will
result in damage to the SimpliPHI Battery’s protective circuitry and will Violate the terms of
the Warranty. SimpliPHI batteries are designed for parallel wiring only to increase the battery
bank’s storage capacity.
4.6.1 – Increasing Storage Capacity via Parallel Wiring
Storage Capacity and total available Amperage is increased incrementally with the number of
batteries wired in Parallel. For example, two SimpliPHI 4.9 kWh-51.2V
nominal
(97Ah) Batteries wired in
parallel are rated at a combined 9.96 total kWh, 51.2 Volts DC and 194Ah. The two paralleled PHI 4.9
kWh-51.2V
nominal
batteries have a combined maximum continuous charge and discharge rate of 97
Amps DC (2 × 48.5ADC).
4.6.2 –Wiring Batteries with Threaded Studs using Battery Cables
SimpliPHI Batteries can be parallel wired from terminal to terminal (daisy chained) up to 4 batteries
with 4/0 cable. Ensure that all cables lengths within the bank are identical in length and gauge to
maintain equal resistance across the string.
Do NOT use power tools or
impact drivers. Doing so will
Violate the terms of the
Warranty.
