Sheet1
| Question | Answer |
| Physical size of the battery was not provided. This includes length X Width X Height. | Size less than < L:12 in, W: 10 in, H: 4 in |
Battery enclosure type? LBC manufactures batteries with: * Standard ABS plastic enclosures, which are similar to standard automotive batteries
* Metal case
* PVC wrap has not been finalized yet but at the moment it is a fiberboard composite
Battery Capacity in Amperage? How long must this battery operate before requiring a re-charge? The battery voltage range of 140-185V amounts to a wide range. Providing a specific voltage with variable high and low capabilities would be better in developing this battery. LBC does need the following: a. Time (hours) @ 30A?
b. How long (seconds) at 60A peak load?
Total continuous power = 4840 W Max Voltage @ full charge = 192 V Min Voltage @ full charge = 120 V Operating Voltage = 140V - 185V Nominal Voltage = 176V Continuous Current = 15A rms (typical), 30 A (peak) Pulse Current = 30A typical, 60A peak (5s) Capacity > 1100Wh Mass < 7kg Lifetime = low priority (~30 min or greater desirable --> again low priority!)
BMS Balancing/Monitoring/Charge SMBus or CAN telemetry
