Phoenix 1.34kWh Lithium-ion Battery 12.8V (RLC-1.3-X1)

Note: 1P4S pack, 105 Ah at 12.8 V in a 12 kg case 260 mm long - the closest thing Phoenix make to a straight swap for a 12 V tubular battery, at roughly a fifth of the weight. Charging limit 14.6 V, cut-off 10.4 V, so it works with a standard 12 V charger set for lithium. Maximum 4 modules in series or 4 in parallel - four in series gives 51.2 V. The Cube series is Phoenix's drop-in lead-acid replacement: an ABS case the size of a big battery, M8 terminals, and a Bluetooth app that reports capacity, voltage, current, cycles, SOC, SOH, per-cell voltage and temperature - the most detailed monitoring in the Phoenix range, and the only one you can read without an inverter. IP65. Cycle life is 5000 at 0.5C, 25°C and 80% depth of discharge, with a design life over 5 years - a real, fully-qualified figure. Warranty is 3 years against the Wall and Rack models' 5. Currents: 50 A recommended, 75 A maximum continuous, 80 A peak for 60 seconds - a modest peak, so it is not the battery for heavy motor starting. Charge mode is CC/CV at 0.5C. One real constraint: modules can go in series *or* in parallel, never both. Once wired one way they cannot be reconfigured the other. Plan the bank before you buy. Phoenix batteries are made by Century Engineering Industries (Pvt) Limited in Karachi under licence from Kukje Industry Battery Co. Ltd of Korea.
