I would like to know if it is possible to replace lead acid calcium batteries with Lithium LifePO batteries. I have a Power UP202 system from Uptech with a 1440W inverter and 2 x 105Ah lead acid calcium batteries. I want to replace the batteries with 1x 24V 50Ah Lithium Iron (LifePO) battery with the following specs: 24V 50Ah Lithium Iron (LifePO) battery Technical Specifications - Lithium Iron Phosphate (LifePO4) Battery Type - 1.28kWh Usable capacity - 50Ah Nominal capacity @ 0.2C - 25.6 VDC Nominal Voltage - Operating Voltage Range: 24 VDC to 28.8VDC - Operating Temp Range : Charge: 0 C to 45 C | Discharge: -20 C to 60 C - Protection : Over-voltage | Under-voltage | Short circuit | Dust and water resistant - Lifespan: 2000 cycles @ 0.2C charging, or discharging until 70% capacity - Dimensions : 328 x 215 x 172 mm (L x W x H) - Terminal: M6 - Weight: 12.8kg Charging / Discharging - Bulk Charging Voltage: 28.8 VDC - Float Charging Voltage: 27.6 VDC - Charge Current: Max 50A - Discharge Current : Max 50A (Burst 100A, - Discharge Voltage Minimum: 24v - Under-voltage Cut-out: 20 VDC - Over-voltage Cut-out: 29.2 VDC - Self-discharge rate: < 3.5% per month The specs of the Uptech Power UP system are as follows: OUTPUT Output Voltage Normal Mode: Built in AYR will boost output voltage by 1.2 when input voltage is less than 200VAC. Battery Mode: 230VAC ±10% Transfer Time 20 min typical Overload capability Bypass Mode: 120% – audible alarm 5 min, then fault mode Normal Mode 115% – switch to bypass Battery Mode: 120% – audible alarm 15 secs, then fault mode 10 secs > unit restarts Battery voltage 24Vdc Battery Type 2 x 105ah lead-acid Calcium Batteries REVERSE POLARITY PROTECTION Floating Charge Voltage 27.4Vdc Constant Current Charge Voltage 28.6Vdc Maximum Charge Current Switchable 10A or 20A
