Hello Everyone, been reading all the great threads! So, Here is my first attack plan :
1) I just purchased a new x-treme scooter XB-700Li with the newly upgraded 48V 20ah LiFePo4 26? cell battery pack (instead of the original 26 cell LiMnO4 Ion battery pack) and I want to add the new Cammy_CC 48V 20ah LiFePo4 pack(has a high tolerance BMS) that I purchased, under the scooter seat as a secondary battery pack to increase the range. I want to hook them together in parallel to create a 48V 40ah pack that can be charged from the charging port on the scooter(I know it will take twice as long to charge). I do not think the XB-700Li has a BMS(the original models did not) and I could recharge the seconary Cammy_CC pack alone to balance the cells once a week or so. What is the best way to hook my new 48V 20ah pack to the stock pack? I think I need to drill two small holes in the seat box and put the negative lead from the secondary battery pack to the last negative terminal (farthest from the negative discharge wire terminal) on the primary pack and put the positive lead from the secondary pack to the last positive terminal(farthest from the positive discharge wire terminal) on the primary pack? I don't want to make to many changes or reconnects to do this mod but, am I correct or am I missing something ??? THANK YOU !!! - I know this is confusing - I can't get my camera to down load any pictures - I will try to down load some photos in the next few days, I HOPE !!!!
