have you measured the voltage? I need to compare the voltage data with the spent battery.

Thanks !!

I have tried it on a giant reign and it works well, although you only raise the limit up to 37.5 km/h and the bike does not show the real speed.

I need a little help to compare data from my battery, I just need a voltage reading that the battery gives when it is at 0% or as close as possible, it is taken through the charging port with the two large pins with a voltmeter. Thanks.

you're right, I left them at 100% and I should have left them at 60%, I'll find a way to download them.

The truth is that I have not tried it but at 10% the bike automatically goes into ECO or some kind of limited mode. So if it were as you say, which is very possible, a solution would have to be found. If with the original battery the dead battery voltage is close to 3v per cell, the bike is...

Yes, I more or less know how BMS and smart chargers work, here we have an added factor. When I assembled the battery for the first time, the original cells were 100% full but the new ones were approx 50% full. When turning on the bike for the first time, it marked 100% charge status, as if...

the two biggest

I need a little collaboration, someone can measure the voltage that the bike gives through the charging port at 100% and 0%, I am doing autonomy tests and there is voltage data on the new battery that does not fit. The voltage is measured with a tester with the bike on. Thanks

We have space problems and the Kevlar is just one more layer of the carbon shell, they are joined in the same process and it is cheaper than carbon, I don't see where the savings are, in this specific case in adding more volume of a material It does not provide structural resistance. Anyway, I...

The original battery has a rubber gasket on the covers and on the connector, you don't have to worry about humidity, I have sealed the covers with silicone for gaskets on mine.

I have designed a complete battery pack that has 28 21700 cells with their caps, in which I have installed the original TQ BMS and its connector to avoid compatibility problems, the TQ system does not know that I have changed anything simply because it has no way of knowing Where does the cell...

This is not possible because the battery needs the original BMS to work, it has Can bus communication and a wake up that is very difficult to copy, it could only be sold as a kit to assemble and I am not interested in doing so. For someone with knowledge in can bus communication and programming...

Difference in weight between the original shell and the carbon shell, this one has 1 layer of kevlar and a layer of carbon of 260 gr.

I don't know if it is forbidden to put links to other forums.... This is the first ride with turbo mode configured with everything to the maximum . In this mode I think that autonomy has improved by around 35%

I proposed this topic here because I thought it would have more follow-up and support than in the mother-speaking forum I usually post to, but I was wrong, so if anyone wants information about the project, look for us in the ebikes reference forum in Spanish . Greetings to all, for my part the...

First rolls and load made without problems.

the price difference in 28 cells is around €100, for that difference if I can, I mount the best available. The complicated thing in this case and more expensive in the form of hours invested is the design of the modules and especially the casing, of which I have already had 2 failed attempts, in...
