I am about to venture into lithium polymers for my second bike. I have never dealt with this type of battery before. From following posts on here I know it can be very dangerous and you must watch the voltage when charging and other factors. The reason for the switch from LiFePO4 to Lithium Polymers is $$$. I do not want to spend over $1500 for a pack alone.
I currently have a nice 58V 11.5Ah LiFePO4 A123 triangle pack on my first bike, pretty easy to manage.
For the 2nd build bike I wanted suspension, 150mm dropouts and a place to put lots of batteries. I came across this type of bike here on ES, its a ISD EXCELSIOR. I believe ES member Brentis has a few named Strong GTS. I got lucky and found one here in Paris for 100€.
I am 215lbs 5ft 11", riding mainly on level flat streets. I want to be able to hit speeds 45mph+ and have some good torque.
So, I bought myself one of these, a Cromotor.
Here are the main parts I need, to get her running:
Controller, thinking of Cellman's 24 fet 4110, 36-75V Infineon Controller, but not sure if this will be powerful enough to handle the volts & amps I need to hit 45mph + ??
Torque arms, already on the list for Doc's new batch.
LiPo batteries, I have no idea what brand, volts & Ah and Size to get.
BMS, not sure?
LiPo charger, powersupply and anything else I would need for these batteries.

I'm sure I am missing more items regarding the battery setup. The bike will need new front forks and better brakes. I have the new rims and tires for her.
The picture with the mock up battery box, the dimensions are 400mm L x 100mm W x 150mm H, so I am not sure how many & what type of LiPo's I can fit there.
So, to sum this up, I need some help with LiPo's, Charging items and Controller. Any advice is deeply appreciated. Thanks for listening.
