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.

the maximum for the lightweight 85SX is 16A. We still use the 85SX in the Woosh Faro but stopped selling the motor in kits. it's fairly straightforward to open the controller (4 screws) and make an extension lead beween the controller and the battery using Anderson or XT connectors.

You can replace the battery + controller (at the base of the battery) with a 36V 10AH bag battery and controller that goes inside a saddle bag like this: The 36V 10AH is good for about 30-35 miles from a full charge. If you want to proceed with this idea, please email support@wooshbikes.co.uk

We do supply components for servicing outside the warranty period.

current control on bikes. The kit controllers still have speed control, I can load current control firmware on request. Your controller is made by JYT. Both Lishui and JYT can supply current control firmware on request. I'll make a video with Lishui speed control later this week for comparison.

I found someone in your neck of the woods, NR5. I have PM'ed you.

yes, that's a pretty good plan. Your controller is YCSH (JYT) brand, not Lishui. Lishui controllers have product codes starting with LSW-something. The good thing about Lishui controllers is their firmware cope automatically with a lot of variations in motors: Hall or Hall-less, number of...

I look that up for you tomorrow

found it at: Bosch Al3640cv 36v Li-Ion Charger With Battery Schematics | PDF (scribd.com)

@StuartsProjects - can you post a picture of the whole schematic or the bottom right? it's too difficult to work out without the missing part.

I missed the part of the schematic in your post #78. Will try to make sense of it tomorrow

Which post is the video in?

Your picture does not show where the red and black wires are attached to.

it's the switch marked SW2. The middle blade is connected on the charger side to BUS (K2, middle ground) and shorts the negative of the high side to the positve of the low side.
