We know how to service the TSDZ2 and 'B' revision outside warranty thanks to the YT videos. We need to see how in practice the DM01 and DM02 can be serviced and where their weaknesses are. If there are any issues with IP, I expect Tongsheng/Aikema lawyers would deal with them, not the end users.

If all the Chinese sellers behave correctly like bmsbattery, I would be more than happy to supply motors, spokes, rims and other components separately and at competitive prices. It's companies like PSWPower selling goods at near wholesale price then underdeclare the value of the purchase to...

Let's say you simply connect the middle pin to a pullup resistor. The battery sends a block then waits. You then heat up the thermistor. Would the line goes low?

Thank you for a nice and clear experiment. I assume the protection signal can be connected to a brake sensor.

The safe zone for your 36V battery is 31.5V to 41.5V. You only need to knock 0.5V off to be very safe, that's equivalent to 5% of its capacity or taking the bike out to ride for a few minutes. For me, the safe practice is to charge only when you know you are going to use the bike on the same or...

Batteries are inherently safer than town gas or electricity if built, used correctly and not abused or soaked in rainwater or sea spray. There is really nothing to worry about when you follow the manufacturers' recommendations. I always take an interest in the e-bikes of the Uber Eats crowd at...

How about asking the LFB under FOI?

40% of 112 fires = 45 kits. It very possible. Just look how prevalent are the triangular frame batteries in the photos of ebike fires. They are not factory built bikes.

may it be beneficial to avoid that characteristic 'flipup' ?

Balancing is automatically performed when the voltage is within 5% to 10% of the maximum, eg 41V-41.5V, depending on the balancing circuit trigger setting of that particular battery and stops when the delta value is less than 10mV.

I haven 't got a theory. All I want to know is how much my customers would lose in capacity with a charger set to 41V instead of 42V. If it's 3% or less, it's worthwile, if it's 7% or more, I'll pass.

I have an ordinary non-calibrated DVM.

I only use SANS charger. I have 2A, 3A and 4A SANS chargers.

At present, I assume that changing to 41V would cause a reduction in capacity around 7% and up to 10% so it's not very desirable in view that the life expectancy of the 42V charging regime is well beyond the recommended 5 years of use.

Thank you for publishing your results. I can order the chargers with 41V output when I am convinced that they are a better choice for those who want longer life and lower risk for their batteries.

Can you confirm that with your method of reducing the charging voltage (was it NealH who suggested using a diode inline?), the effective reduction in full charge voltage is from 41.7V to 41V? That would giive about 0.7V difference. Saneagle did not give much details how he charged the pack to...

we fit only our kits though.

Is there an association between a Suron and canabis? QUOTE: The court heard that Hall is “an anxious person who cares for his brother and partner’s child”. Hall pleaded guilty to a number of offences. They were driving without a licence, driving without insurance and assault by beating of an...

I reckon they are worried that you are going to destroy the motor they supply. They would be happier if you use a lower RPM motor which has better yield at slow climbing speed.
