4.5.2 – Torque Batteries with Threaded Studs

AmpliPHI Batteries with threaded stud terminals have a torque specification of 121 in-lbs. (13.3 ft-

lbs.).

Threaded Studs = 3/8” (10mm)

Torque Value = 160 in-lbs

4.6 – Electrical Wiring

CAUTION: All AmpliPHI Batteries are designed to serve at fixed voltages and cannot be

wired in series to increase the battery bank’s voltage. Wiring the AmpliPHI Batteries in

series will result in damage to the AmpliPHI Battery’s protective circuitry and will Void the

Warranty. AmpliPHI 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 units

wired in Parallel. For example, two AmpliPHI 3.8 kWh-51.2V

nominal

(75Ah) Batteries wired in parallel

are rated at a combined 7.6 total kWh, 51.2 Volts DC and 150Ah. The two paralleled PHI 3.8 kWh-

51.2V

nominal

batteries have a combined maximum continuous charge and discharge rate of 75 Amps DC

(2 × 37.5ADC).

AUTION: Using an impact driver or power tools on the terminals will Void the Warranty.

Using power tools or impact drivers may damage the terminal even if it doesn’t result in

breakage. Only use accurately calibrated and properly adjusted torque wrenches when

tightening terminal hardware.
