Ravi, That's a really interesting position and plan. I'm assuming you're building 14s battery packs but advertising and managing the packs as 13s (48v). Aside from those folks who buy soley/mostly on specs I don't see a real downside for bikes with mid drive configurations where top speeds can...

That's what I use them for. 9 spd Shimano 105 road levers with V brakes (I think they're Nashbars) on my road/gravel ebike. It's not like these levers don't work at all, it's just that the braking force seems better with the TAs in place.

So instead of settings with voltages and/or percentages of a voltage and amperages it would be switches for specific functional settings? I think that would work for a lot of folks. I hope a display for voltage and amperage monitoring is something that can be kept in the design.

Define "booster". I ask because I've read different descriptions of brake boosters. The TAs don't change the total amount of cable pulled by the lever, it just becomes non linear. With the TA's cam setup the first part of the lever travel pulls a different amount of cable than the latter part...

They increase the amount of cable pulled by a little bit when the brake lever is initially pulled. So less pull on the lever creates a bit more leverage at the brake itself.

The TAs are indeed a great addition if someone was upgrading from something like road type brake levers to use with the V brakes. If a bike already has the appropriate levers in conjunction with the V brakes they wouldn't be needed ... although I have heard of folks with smaller hands or those...

It's not really an issue of max wattage, for example most popular off road setups for ebike conversions are mid drive motors that are substantially less than 1000w. High speed big wattage setups (DD hub motors in the 1.5-2kw+ range) are heavy and generally unsuitable for off road use unless...

I'm not sure. The 52v battery I have is in between two in the list in terms of capacity (a13 and a 16Ah) so I use the lower of the two. I don't know what the internal resistance numbers are for those two pre defined 52v batteries . For grins and giggles I have used my battery's actual measured...

Not with the Grin batteries. Their 52v batteries using Panasonic 2170s in Hailong cases have anecdotally (various forums and Grin) been very reliable ... albeit also a bit expensive. For me one interesting characteristic of choosing 52v in combination with a smaller hub motor for an urban...

Total weight? (you and the bike) Define "large" hills (grade and distance) Wheel size? (road bike, MTB, small -sub 26") How much help? (human power) Take a crack at these numbers (approximations are fine), for now assume a PhaseRunner controller, 52v battery and a GMAC (8 or 10T) motor and plug...

You'll probably find a few around here but I'd also suggest posting on https://endless-sphere.com/forums/ There you'll find much broader and deeper experience with Grin's products.

Yes, and that's actually easy to understand (if you think like the city) ... Falling off and a possible injury from "snow on the path" or other obstruction = your fault. But a fallen road sign could lead to the city being possibly/partially responsible in the event of an accident.

Nice today (-5C) but the high tomorrow is -15C. Below average snow so far this winter, just over 40cm total and less than 20cm accumulated snow depth (what's on the ground). Despite that (and possibly because of it) I still have to fight with the city about how often the city wide MUPs are...

I'm not sure I understand the point of your post. This thread's topic is experiences with the extra features with some commercial battery chargers. Gionnrocket offered an alternative example of those features with a less expensive DIY version. Your sum total contribution appears to be to snipe...

Who says it has to cost hundreds? You can spend 10s of dollars and monitor and manage the charging externally, do some inexpensive DIY and make the monitoring automatic, choose a commercial product with fixed voltages with those features for $100 USD, or you can spend 100s for extra flexibility...

Condensation issues are not usually present when you are riding, it usually only becomes a problem when you bring a cold battery back into a warmer moister environment (your house). To get technical you won't get condensation forming when the dew point is below the ambient temperature (which is...

I hope you enjoy walking. This guy is well known to the police but I assume like all of us he isn't squeaky clean in his riding. His popularity would however be a big problem (less success in citations or prosecutions) if he was also a habitually bad rider. He also doesn't normally directly...

Is she related to the little cutie in Copenhagen? ;)

15+ years of riding with hydraulic disc brakes, Shimano and Tektro. Most of this time has been with the Shimano brakes, the Tektros work fine but require that I use a special fitting to add oil. Each year I top up the reservoir on the brake lever with mineral oil purchased from a local pharmacy...
