Saft Tel.X Ni-CD 1.2v 180ah 216wh - Fully Tested
These are excellent batteries for solar storage. They were used as BACKUP ONLY for telecom and they are testing great. You will get a printout of the test report for each cell and you can choose the capacity in the drop down menu. We did an 18a charge to 1.45v, 18a discharge to 1v, and 18a recharge to 1.2v. These batteries can certainly handle more amps but we would recommend to keep the amps below 180a on a discharge and 85a on a charge.
For a 12v battery you will need 10 of these in series. Fully charged would be 14.5v, discharge to 10v. No BMS needed. Just add busbars. These Saft batteries are preferred by the telecom industry for their off-grid battery solutions.
Rated for over 1000 cycles.
Operates in temperatures from -20°C to +50°C (-4°F to +122°F) and tolerates -50°C to +70°C (-58°F to +158°F) for short durations (referred to as a period of less than 96 consecutive hours and a total of no more than 15 days in one year.
At +25°C (+77°F), the lifetime is 20 years. At +35°C (+95°F), the lifetime is 16 years; a reduction of 20% for a Ni-Cd battery compared to a reduction of 50% for a VRLA lead-acid battery.
