Re: Panasonic tesla cell battery?

FWIW, I received the 21700 cells I bought from tonycu41. I didn't have much of time today to fool with them, but I did a manage to perform a brief sampling with one cell. As received 3.62V, I charged it to 4.10V @ 750mA then waited 30 min before loading it. After one hour loading at 1.25A, it measur...

The listing itself has no mention of tesla at all, what do you think?
This one does (same seller): https://tinyurl.com/yyfftcma
He also states they originally came from a "pack"

Re: Panasonic tesla cell battery?

I purchased a few 21700 cells from ebay seller tonycu41 https://tinyurl.com/y3yqexaz Not received them yet. Stated they are new from an unused 'pack', one year old. It's doubtful they came from a genuine Model 3 pack because the model 3 cells i've seen have a bare metal shell & recessed positive ter...

Re: Delta trikes vs tadpole trikes

For a given height of center of gravity and a given track at the paired wheels, a tadpole will always have better emergency handling(combination heavy breaking and sudden turn) than a delta. With double the contact patch at the braking loaded end, and the braking force vector will usually stay betw...

Re: e-Tricycle for adults

I sure wouldn't go for the above seat steering option, though. I've had a chance to compare above and under steering on the same bicycle, and I found that my back and rear are less tense when my arms are down, so I sit more comfortably in the seat. The above seat steering mast was somewhat in the w...

If he's ok always being under 12mph or so, delta would work. Regular periods of higher speeds tadpole would be better probably.

Re: Inverter recommendations, 48V sine wave, no grid tie

Yes, inverter has a small muffin fan, but is thermally controlled so it doesn't run on anything but extended, max amps. The space heater has two settings - 800W and 400W. The inverter doesn't like either.
