Hey forum! I'm new here, got sent from a different forum, to ask here too.
I'm planning on building a 5000 watt, hub driven, electric bike. It's a complete kit you can buy from ebay:
https://www.ebay.com/itm/E-Bike-Hi-Power-72V-5000W-Ebike-Conversion-Kit-Panel-Display-Electric-Bicycle/183593899318?var=690995258460
Now, this kit does not include a battery. So I have to get one. I'm not experienced with electrical systems.
I have two main options:
Get 2 72v batteries, that are 15ah, and 30A max output, and wire them in parallel:
https://www.ebay.com/itm/72V-15Ah-Ebike-Waterproof-Lithium-Battery-Scooter-Battery-Pack-for-1000W-1500W/254164384436
This would be the cheaper option by far. And it would be a total of: 72v, 30Ah, 60A max continous output.
Or, get one complete pack:
https://www.ebay.com/itm/72v-30Ah-LiFePO4-Battery-Pack-for-E-bike-E-scooter-2500W-Motor-5A-Charger/202269099747
This would cost me 300 USD more, because of shipping mainly. And, it would be 72v, 30Ah, but only 50A max continous output.
Now, the motor I am planning on getting needs ~80A, but not sure, if that means peak. I'd be more than enough with 60A though, but just asking, because that option is cheaper, and looks stronger.
Wich one would you guys suggest me to get? Why? Thank you!
