Hi
I'm a everyday cyclist, using a xiongda XD 2speed motor to haul my fat ass to and from work every day. Until now i've been using 3 4s 10000mah multistar batteries, Works allright, but seem's to slowly loose capacity, i've done about 150cycles normaly down to about 3.7-3.8V at rest. Now i'm wondering Why not switch to 18650 type batteries, as they probably will be much safer and longer lasting. I'm not looking for High speed nor light weight but longevity and ease of use.
Looking at the best bang for my buck, i've fallen for the Panasonic 18650pf at 3.25€/piece or 3.65€ including soldertabs. Want to buy 72 pieces for a 44V 6S battery, as i have a 12S bestech bms in the mail next week.
My normal powersetting is level 3 ie 250w or about 5-6A continuos. My charge-discharge
voltages will be 4.15V - 3V, so i suppose I'll get about 15Ah out of the pack instead of the theoretical 17.4Ah
I see there is multiple different 3200-3500mAh cells out there, but the last few mAh are much more expensive than the first 2900! So Why not go for the 2900mAh pf's?
Are there any reason to go for an other battery maker?
Any thing i shall be aware of?
