As the Hub Motor Turns and the LiPo Fire Burns. Smart batteries.
I know that these SONA batteries will not go 5 miles on a full charge.
I had an important doctors appointment today with a new heart doctor. I had to be there at 2:45 and was actually early.
About 1/3 the way there and 2/3 of the trip back there is about 3 or 4 blocks of very heavy traffic and busy intersections with people getting on an off the expressway and State st. which is the busy main drag between Schenectady and Albany. The capitol of NY state.
Those four blocks it makes sense just to walk the bike on the sidewalk when possible so I do not have to stop and start 20 times. Therefore out of 5.4 miles I only rode about 4.6 miles. Mabye 4.7 but definatlly not any more than that. Speed was top 16 mph today and normal around 12 mph.
The batteries did not make it home. There is a cuttoff for people like me who abuse batteries. I had to walk about 1/4 to 1/3 or approx. 0.3 miles home as there was no slowing down. The batteries just shut off like if I hit the kill switch.
The picture at the top shows the cuttoff voltage. Since I was cruizing about 13 to 15 mph at the time I imagine taking SAG into consideration it looks like the BMS shuts the packs down at 35 volts.
This is troubling as I have a follow up appointment in two weeks for important tests in one month I have to see the doctor again reguarding my Blood pressure medicine.
I really need two more packs like the SONAs so I can switch packs there for the way home. I cannot screw this up as it is my health at stake here. The 24" cargo bike will not even run the SONA packs and the old LiPos are only good for Wall-Mart and the grocery store at Hannaford plaza. It is about one mile away and 2 miles round trip. I was planning on using them exclusivelly for that trip and when they fail someday to get me home or can no longer go two miles I will have to retire them.
The single 8.0 - 6S LiPo pack has an unstable cell (see pic second up from bottom) I just hooked it up for a second tonight just to make sure my variable controller was still good after the batteries shut down. I figured it was the BMS but wanted to be sure.
I had that pack on BALANCE CHARGE for hours and even tried to balance it at 1 amp and that unstable cell just got worse. I really do not want to run it as I do not want to breathe any smoke if it decides to pop. Basically I do not want to order any more LiPo batteries. I definatlly do not want Lead ass batteries.
I would rather build my own pack from 18650 cells which could run on either bike. 54 volts may be too much for the variable controller so am looking for 48 volts or around 50 volts like fully charged 12S LiPo. I would actually like to build two packs which snap togeather.with a non solder kit. As far as a BMS I am willing to try that as I think they do sell a non solder BMS with the packs.
Since the SONA packs are made from 18650 cells I now know since both 4 mAh packs were in parallel today that 8 Ah is only good for 4 miles. You can all tell me different but google maps don't lie. mabye the ratings on the SONA packs are a lie. Anyway Since I really do not want a complicated smart battery which shuts the pack down at a set voltage I will calculate the size of the pack accordingly.
8 Ah = 4 miles
16 Ah = 8 miles
20 Ah = 10 miles.
I would like to build a 20 Ah pack from 18650 cells. Also I am very confused about the two Lipo chargers I have. I think they will charge 26650 cells if I run 6 in series however do not know if they charge six 18650 cells in series. It is why I have been interested in the 26650 cells so I don't have to buy an expensive 48 volt charger. Also the maximum capacity on a 18650 cell is usually only 2,000 mAh or 2 Ah where the larger 26650 cells are 4 Ah usually.
I would need 10 rows of six - 18650 cells in parallel series to get 20 Ah with 18650 cells. 5 rows of six would work with 26650 cells and will work on my Skycharger and mega charger and I could charge two packs at the same time for 12S. One pack on the Skycharger and the second on the 400 watt Mega- charger.
Also about a week or so ago I was at Srewerts and talked to an older guy who drives a tow truck for a tow company. He was checking out my Currie. He told me that the impound yard has at least 50 e bikes that police impounded in the last three years.
According to NY state anything with a motor is a $250 fine for an unregistered motor vehicle and automatticly impounded. The inmpound won't sell them and they go to the scrap metal yard.
I am definatlly not happy at all about this and feel like someone is lying to me. Either the guy or people here. There can only be one truth. Federal law states 750 watts and 20 mph. NY state law says any type of motor vehicle needs to be registered.
I really do not want to punch a cop in the face at my age and the 800 watt cargo bike has a $260 hub motor on the back. Also the Currie is my first e bike and I love it and might even shoot a pig with his own gun to keep it. I may sound crazy but actually when I went to state prison for firearms I took ART. Aggression replacment treatment. They taught me to avoid stressfull situtations which I actually try to do.
Therefore I will be building a new bike out of used parts to run exclusivelly. (see bottom pic) If it gets impounded I will just do the 10 or 15 days in jail as I refuse to pay a $250 fine. Then when I get out I will be moving out of NY state to a state which allows e bikes on the road.
The used 48 volt motor I have had for years which has been repaired on the inside with a terrible solder job. The old 60 tooth spoke kit and a $8 variable controller. The bike was $7 from an old guy that collects cans. Please let me know about the 18650 or 26650 cells and which will work with my LiPo chargers. Thanks.
