at the moment when i was reading the accorn brand lipo instruction i saw that the cut off should be at 6.4 but my esc cut of at 6.25 only so dunno if advisable to use or not someone plz help advice please
i am using rooster esc on a tto1 haven got lipo yet planning to get a few in a few days time so need advice
your advice would be most appreciated people THANK YOU
1. brand of batt.
technology now is quite gd lah, so any brand of lipo is gd enuf
I'm using ORION 3800, i go for these batt cos of its carbon looks only
2. how long it charge
normally, its charging
not more than 1C, meaning if ur batt is 3200mAh, charge at 3.2A, <1hr to full charge
if batt is 5000mAh, charge at 5A, <1hr to full charge
unless otherwise stated, eg. my ORION state there,
DO NOT CHARGE LESS THAN 1C OR MORE THAN 2C, meaning, >3.8A or <7.6A, but my charger max is 5A, so i charge 5A, <40mins
3. do not discharge ur batt to less than 3V per cell, 2 cells = 6V.
when on load(batt is connected, motor is running), batt voltage will be lower, when off load, batt voltage will rise slightly.
so, when ur ESC read 6.25V, it cut off. so its time u charge the batt, it voltage shd rise a bit, probably to 6.4V.
4. lipo self-discharge can be as low as 2% per year, so , how long do u wanna leave it on the table?
