Hi ladies and gents. A bit of a noob question. I am converting an old motorcycle and just need to try and understand how to build the battery. I am using a 72v 10-12kw hub motor from qs motors it draws approx 140amps continuesly, I need to ride at 5 hours straight mostly highway kms. I was thinking of using the LG 3000mah 20A batteries but would use a less Amps battery for more mah trade off. What size battery do I need to build? And can I get away with joining 3-4 batteries together all with 150A bms? If I go down the 4 separate batteries route do I have to use 4 chargers for each one or tie them all together for 1 big charger? For my application do I need the high drain battery? Cheers for your help
