I have the 36V 10AH pack
Charge rate <20A, 2A balancing charger provided no BMS on the pack itself.
Discharge rate 3C continuously and 5C peak, for up to 30 seconds
D -- Description of tests or riding = motor, rider & cargo weight, hills, speed, distance and meter reports.
Battery ran a 36V GM 500W motor with rider and bike weight including the battery at near 260lbs. Motor slowed significantly on hills. Speed was in general 18-20 MPH. Approximately 20 miles per charge with minimal pedaling on accelerating from a stop.
E -- Estimated number of cycles and depth of cycles actually performed so far and voltage and capacity difference from new.
Estimated 100 cycles with 10% to cutoff no notice of change in voltage or performance.
Batteries at 3.3V after full charge and three weeks of storage.
F -- Feedback on dealer or Mfg accessability and response to any problems or questionsâ€Â
Product was in my hand within a week of ordering it. Questions answered promptly untill then. After receipt of goods typical Chinese communication wise mostly one to two week in answering e-mails. I did not phone them may have been better if I had.
I ran the pack in series with a couple of 9AH 12 volt batts in parallel for 48V for the last 500+miles. Acceleration and hill climbing abilities were much improved and the miles per charge was maybe at maximum a mile less.
I just purchased a 48V pack as the 36V has done well. It is now in my grubby little hands so will report on it in the near future.
OK the future is here pic of the newest 36V pack I sent in as requested to have converted to 48V cuz my 36v controller fried. Replace the controller with a 48v unit and added a couple of 12 SLAs to get the voltage right. Instant torque junky I am.
Near five weeks to get, it back and was beginning to get concerned when I got an e-mail from Zane with saying it would be on its way. The pack arrived three of four days later as you see it. Not quite the same build quality but figured It was still serviceable. So set about splitting the pack and made boxes to put in the panniers. So when I drop it things will still work. Bent the ABS with a heat gun while clamped between boards. The rewire from what looked like 26 gauge to 20 gauge took a couple of hours.
First charge shows a weak batt. Second charge the weak battery started melting shortly after I hooked up the charger. E-mailed Zane and got an immediate response five more batts in my hand in less than a week. Replaced batt #3 rode 17 miles. Replace batts #7 and #1 as the full charge lights came on as soon as they were hooked to the charger. Replaced batts #1 and #7 again as the new ones got hot as soon as the charger was plugged in. Next try at charging everything seems to be good and the charger shuts itself off about four hours later. Another 17 mile hot Roding it all the way ride 20-23mph flat out with a top of 25 even a couple mph higher on hills I often rode 17mph now going 19mph up them. Expect the same mileage out of this one as the 36v as I ride and accelerate faster. I hate the panniers mounting assembly as they keep nearly falling off the bike so finally got the zip ties out. A couple of ties installed at the bottom and no more problems.
Looks like Foxpower comes through again albeit a bit shaky this time. Excellent support after my first bad battery problem.
4/3/09 Update on the Foxpower 48V 10ah Lifepo4 pack.
Put a few more cycles on the new battery pack and even with the dc-dc converter powering the new LED light set up managed near 19 miles. That was straight without stopping for a break as I usually do. Only pedaled from a stop and up the hills that tried to slow me down to less than 20mph. Temperature was about 50 F. Had a nice ride today with no one trying to run over me, no flat tires, rain or breakdowns. Hard to beat that kind of ride although some of that elusive sunshine might be nice. Oh and the total vehicle weight is near the 255lb mark.
). When I'm doing that the pack LEDs blink a single LED, which usually indicates time's up buddy, but clearly if I let off the throttle they recover the volts.
