Valence u24- 12xp 12v 110ah lithium ion battery 18650 power wall leisure. 12v lithium iron magnesium phosphate battery. These have been used in robotics and have only ever been discharged to 50%, approximately 6 years old. I have the diagnostic software and the recorded discharge cycles is between 4 and 8.
Valence have now changed names to Lithium works so please check these out as they report a 4000 cycle life at 80 depth of discharge. Direct replacement for lead acid/agm's, remember you can only utilize 50% of your lead acid batteries where as with these you can use 80% of the capacity with no harm what so ever. They have an internal BMS that protects against over charge, over/under temp, they will shut down at 10.5v to protect the internal cells, they have connections so if you are using them in series or parallel link them together and they'talk' to each other constantly maintaining a balanced voltage across the bank.Any questions please don't hesitate to contact me.
