Thanks mate, I was struggling to find an eBay source

i got it from them and the screw to open for batteries was like glued in or something i had to drill it out but its fine and they gave me a partial refund due to that.

Hint hint nudge nidge :grinning:

This is my new one: 42V 4A https://m.aliexpress.com/item/1731012609.html?spm=a2g0n.orderlist-amp.item.1731012609&aff_trace_key=33533f2470d147a4bbd7202a5fc69b4f-1540677648138-02877-N7Mrfi6&aff_platform=msite&m_page_id=7150amp-vtM9rgqKk-ALSogPfCk6SA1546585171583 This is my old one: 42V 2A https://eskating.eu/product/2-amp-charger-10-and-12-s/

I would say battery max 60a is a bit much for the maytech 4.12 vesc. Wouldn’t set it higher than 35a.

Hey, maybe someone knows a working coupon code for APS?

I don’t think they really have any unless you have order something from them before.

They had 25% off on Black Friday… a bit late now for it.

So after having the charger turned on for an hour while it shows green the voltages of each group is now with the charger plugged in: B1: 4.17V B2: 4.22V B3: 4.21V B4: 4.22V B5: 4.22V B6: 4.22V B7: 4.22V B8: 4.22V B9: 4.22V B10: 4.22V

There is a 0.05V difference does that mean my pack is out of balance?

After pluggin the charger off and letting it sit for a while the voltages are still the same.

I will take the board out for a ride and drain the battery to around 34V. When I come home I will plug in my old charger and charge it up.

About time lol. When you get home, plug up the charger that balanced them properly. Let us know what that outcome is

I wouldn’t worry now. Just monitor the individual pack voltage for the next time and have a look if it gets worse.

Guys, when you measure individual parallel pack voltages, do yo keep the multimeter negative probe on the total battery negative at all times and go from 1-10 on the positive probe side and do the math afterwards?

The problem with my multimeter is that once I get into double digit voltage by parallle pack 3, I have to switch it to a mode where accuracy is only 1 decimal place.

Can I use both the positive and negative probes of the multimeter on each individual parallel pack?

I’m assuming you mean once you get over 10v you switch to 100v setting?

If so, you can still use the 10v setting and measure higher voltages (within reason). It won’t damage your meter. It’s more for decimal precision

not so much worried about the damage, but the multimeter won’t display the voltage if it isnt in the right display mode :frowning: maybe I need a new multimeter. this ones like 10 years old and I got it for 10 pounds haha

200v setting then

Yes as long as you have access to both end of parallel pack.
