| Essential Accessories | Note that for connecting the battery to a PC a USB “printer” cable is required (one is supplied with each battery) CAN Bus Termination Resistor – one required per battery (one included with battery) CAN Bus Cable (RJ45 LAN Cable)-one required per battery (not supplied with battery). Note some inverters will require a special (non-standard pin configuration) cable – see installation manual. |
Notes to the specifications
- DoD = Depth of Discharge, recommended up to average daily 80% DoD for extended life, 50% average DoD for ultra-long life. Max allowable DoD is 90%.
- Voltage suitable for various high DC voltage inverters. Please enquire with Freedom Won for pairing support.
- Fly Leads 1,8m long (15/12; 20/16; 30/24 HV). Fly Leads 4m long (40/32; 60/48; 80/64 HV). Power cable Red = Positive, Black= Negative, conductors in the table refer to one electrode i.e. per positive and negative connections. Longer cables are available on request. Multiples of 6mm2 DC cables are available on request for inverters fitted with MC4-type connectors for the battery input.
- End of Life (EOL) is defined as a cell dropping to 60% of Beginning of Life (BoL) capacity for expected life and as 60% of BoL capacity for warranty.
