If one battery pack is preferable over the other as I think you’ve just described 52 V is better then 48 V because of efficiency, is there a max voltage on your scale that peeks in its efficiency. I’m running both batteries,starting out with the 52 volt and will use the 48 volt as a kicker battery to bring me home.
The electrical characteristics of the 72V 100AH Lithium battery are much better than those of a 72V AGM lead battery. The voltage of the battery is 72v. Usage is an electric two-wheeler. The battery capacity 100Ah, and the type is lithium-ion with a shelf life of 3years.
A key factor in the design of battery packs is the internal resistance Rint [Ω] . Internal resistance is a natural property of the battery cell that slows down the flow of electric current. It’s made up of the resistance found in the electrolyte, electrodes, and connections inside the cell.
At about 90% charge, it may sag to 50 volts when riding up a steep grade and pulling 2000 watts. In the end, I want to be able to use my existing battery up, but still enjoy the extra power from upping the voltage using the extra series pack. Then replace the packs with a 60 volt or 72 volt pack at a later point.
Because the 60V battery can provide more amps at a smaller voltage because it has more cells in parallel compared to a 72V battery. Its a BLDC motor. If you apply a small voltage the motor will spin slow and vise versa. The motor has a certain KV rating which means rotations per Volt.
Safety use is 100% depth of discharge guaranteed. The model is LI-ION 72v 60AH, and the voltage is 72 with a 60ah capacity. It has a standard charge current of 5-10A. The maximum charge current is 20A, with a cycle life of 500-800 times.
