This is Vinay, we are in need of high capacity high power automotive specified lithium ion battery, a compatible charger.Capacity: 60AH at C/20 discharge rateVoltage: 144V nominal, Voltage at full charge can be above 150V, but voltage at lowest depth of discharge should not fall below 140V - Hint: Usually we additional cells for certain Li chemistries to achieve this. Total number of cells, and voltage range of battery pack should be specified for each chemistry. Battery charge and discharge curves must be provided.Current:1) Discharge @ 23°C Max. Cont current : atleast 150A Peak @ 60 sec. : atleast 300A Cut-off voltage : Depends on battery chemistry (e.g LiFePO4, LiPoly etc)2) Charge @ 23°C Charge methode: CC / CV (at charging voltage) Max. cont current: atleast 60A Cut-off voltage: depends on battery chemistrySpecific Energy: atleast 90Wh per kgSpecific Power: atleast 450W per kgCell Chemistry: Either LiFePO4 or LiPolymer.Cost per Ah: ~Ask Buyer
