A lead acid battery will only deliver 50 to 60% Depth of Discharge (DoD) before it starts to sag. Most controllers have a low voltage cut off from 29v to 39v depending on the specs of the e-bike manufacturer. The lower the DOD you continually use the lower the number of cycles you will obtain from your pack. Think about using a second battery pack wired in parallel if you think you are pushing your batteries below 50% DOD. The number of charge and discharge cycles you get out of your battery will increase and save you money in the long term. One charger will charge two battery packs easily.
