The dilemma though is the trade off in capacity, M65A offers another 8.33% capacity over the P60C. For the only real benefit of charging faster, which on paper is capable of a 0-80% charge in 10 minutes, compared to the M65A at 1 hour. Problem is though that 10 minute charge realistically...

I would also consider a battery / solar generator as previously mentioned. Generators going to be large and noisy and really overkill for the sub 600w load even the fast charger will demand, also looking at HF cheaper as well. Of course it's a bit use case dependent but if you are only after one...

Good screen grab of the cell with some more information on the bottom. Looks to be a Ampace cell not LG like was previously thought in in this thread. Looks to have the model number of "PD200A" and have a 19.4ah rating. Using this I was able to find a article about the new cell where they...

I'm sorry for the confusion, I was trying to speak on the capability of the new 700wh 4650 pack and how it's hard say if it can charge higher than the current 12a charger without more technical data. On one of the older threads I recall a shop opening up a gen 1 800wh due to some tech issue and...

Great write up, only thing I will mention is the weight difference is likely not that extreme for the old vs new 21700 cells. Bit of Deja Vu but you are comparing "typical" quoted weight figure on the M58T vs the "max" weight figure on the M65A. The "max" weight of the M58t is 73.2g, so only a...

What's surprising to me is that comparing the new 700wh to the old fixed 800wh the energy density only went from 214wh/kg to 220wh/kg or a 2.8% increase. I wish we had some more technical data on the exact cells used, I was expecting a bit better honestly though. Looking at the LG m58t found in...

It's too late, I'm sure it's a problem where you live but in my town many people have been complaining about "e-bikes" ridden by kids not respecting any laws and causing problems. Calling for legislation, high enforcement and banning in area's previously allowed. I've only seen a few people...

I haven't seen you comment about any predictions, numbers were mine but looks like we are thinking the same things then 😆. Reason why I came to a different and smaller weight gain was the M65A lists a max weight of 74.5g/e while the datasheet I found on the M58T lists it at 73.2g/e max. But...

I would note that the cells I mention above would be around a 15% jump in capacity. Avinox seems to have been more speaking on larger jumps, as right after that he mentioned they don't expect a doubling of capacity. So with that in mind 15% would be more of a minimal jump than previously seen...

Personally I find it very unlikely that we will see the 600wh become 800wh and 800wh to 1kwh for the same size and weight. What this means is we would need to see roughly a 25% jump in cell density for the 800wh pack and 33% for the 600wh. Also worth noting the density % should match for both...

I would agree that I believe this is highly likely, everyone is focused on the next big jump while ignoring the small jumps in progression that keep adding up over the years. Right now Avinox for example is using a cell that's been out for over 3 1/2 years and is 284wh/Kg & 786wh/L . Already we...

I look forward to reading more about the build. I recognize you from the E22 threads, I personally thought a lot about building something similar with the E22 and later E55, 72v but with the M620 modified. But at the time I decided to hold off due to cost, ultimately ending up with a electric...

Unfortunately yes it can get confusing and even vague, especially when local governments inside a state can impose even further restrictions. I wouldn't trust sites like those though because they like to give their interpretation on what the law states even if that's not what it says (Also I...

Only for 6 states California, Indiana, Nebraska, Nevada, Oklahoma, Washington. Federally and for most states it's 750w rated (not including local laws)

I don't, if ebikes with cadence sensors are allowed which require basically 0 effort to get 100% power then why limit the assistance % of torque sensors. Unless I'm misunderstanding what is being proposed and cadence would also no longer be allowed, which could have drastic affects to the cheap...

If you are killing batteries in 3 months something is seriously wrong with the quality of those packs either with the components or cells used. Without knowing more about the motor and battery you've used it's really hard to say but using quality parts 1000w+ is no issue even for modern cells...

I like this update, gives the control and responsibility back to the user to configure the motor for local laws

Well that depends on where you are in the US though, not every state decided to go the California route and limit peak power to 750w (which just happened this year so I agree I don't see them going back anytime soon). Not to hate on Rob but the article is wrong on the laws in the US especially...

A little bit off topic but we have had 21700's with over 5ah for years now, for one that comes to mind is the LG M58 / M58T which was available for hobbits almost 3 years ago. Which is advertised as a 5.8ah cell, and is almost certainly what DJI using in their avinox batteries (or a very similar...

I just wanted to mention the US doesn't have different wattage limits for any of the classes, "class 1" doesn't matter in this case. Also the 750w limit federally isn't very clear on if that's rated or peak, and has been somewhat left to interpretation unlike the EU. The wording being "an...
