help me understand charging for the adaptto. or help me confirm that I understand (I know for the experienced this is dead ass simple).
to start my setup.
adaptto mini-e with onboard bms
motor: cromotor v2
battery
just ordering now) 20s9p of 18650 25r cells(made up of 5 x 4s9p pack in series, balance leads to bms). = 72v(nom) 22ah battery.
that gives me roughly 1500watt hours of battery
now the beauty of the bms is that I just need a power supply, heres where I'm double checking I understand. Most chargers are rated as Watts. so a 500w charger could be 12v @ 41A or 48v @ 10.5A. For my purposes higher volts is better to help keep temps down. Even some pc power supplies say they are rated at 1000w, but because they are 12v output, that not ideal correct? this is why people are running to server psu's as they can output to 48v.
a 48V @ 10A charger would be a 500W charger. this would be a roughly 3 hour charge time (1500wh pack) correct?
I guess where I struggle is that to get decent chargers it seems like a pretty good expense. I need 2 chargers (1 for work and 1 for home)
most 1000w 48V psu's I've found are in the 250$ + shipping, so this puts me at 500$ worth of chargers to have a work/home setup.
am I missing where people are finding cheaper 1000w chargers? Is it simply the convenience of a 90min charge that people are going to these 1000W + chargerS? I supposed I could buy a 1000w charger for home and a cheaper 500w charger for home as I'm usually there for a full 8 hours.
other info is that both work and home I only have access to 110V ac outlets (no 220 currently) How low of a Volt psu can I go before heat will become an issue? ie is a 12v 40A charger a bad idea?
what have other people done?
