LTWOO ER9 & ERX - Electronic groepsets

[zerstorer]

How's everyone's experience with battery life so far? I bought 2x 800mAh batteries. I didn't really pay attention how far I got with the first charge. When I charged the groupset for the second time, I reset the shift counter in the companion app to zero. I have done roughly 4.800 shifts now and the batteries are at 35%. So I should get around 7000-7500 shifts out of a single charge. The bike has done 2.300km with this groupset now. I guess I could do at least another 200km. Some of this was on the indoor trainer, however. Though I do not use ERG mode there, so I shift quite a bit on the indoor trainer as well. All in all, I guess I can expect 1000km per charge without pushing the batteries too much into the red. But if there are batteries with more capacity, this could be increased maybe?

I am at 4800 shifts and at 55%. Using vapcell f12.

However, you should simply charge when at 30%. Don't stretch the batteries too much if you can help it.

It's 26€ handling + vat on 170 +-. Mostly between 45 and 50€.

i am from BE and rideing the er9 groupset, I payed an extra 30€ on tax. They put the price lower without asking them .

But what I read about racing it in kermesse ... I don't know but if you pay 400€ you really can't compare it to shimano or sram. the groupset is okay but not more than that. I wouldn't recommend it to people who really want quality. I was riding this weekend in bad weather and the shifting reactions where just bad. Sometimes you just have to shift like 10 times before the RD reacts to it.

Worth taking the risk, sram front shifting was horrible never going back to that. I'll try to put something over the connections to protect it from water ingress.

Note 3: the group talks to my garmin edge: battery indicator as well as which gear i'm in. I bothered setting that up only 3 days ago. It's quite neat.
Bottom line: charge your group...

Yeah, that still doesn't work for Wahoo users though. The head unit randomly gives a low battery warning even when the groupset is fully charged. They still haven't fixed that bug.

Ordered eGR on 3/11 and the came on 3/19,  didn't pay for air shipping but they got here to Texas in a week.  Pretty nice set up again.  I am disappointed that they don't ship it with mineral oil bottle, olives and barbs, or seatpost battery plug, but overall happy to this point.  Waiting on cassette and chain to install.

Mine came with olives and barbs in the bag with the caliper mounts.

I am using a hanger extender to run 11-50t. Will report back on shifting.

As I am running 1x, it seems like the buttons on the left lever are completely redundant. Any way they can be used for something else? Like changing Garmin screen? Or can I set them up like SRAM left/right shifting?

Where did you buy hangar extender?

[gloscherrybomb]

They're generic, give it a Google. Ebay for cheap.

They come "free" when you order 11-50 cassettes on ali more often than not

I just pulled trigger on the ER9 over EGR even though its going on a gravel bike. This will replace Ultegra/GRX setup. My plan is to run it in 11 speed mode and keep current crank, chain, cassette (11-34) as it is. Will see how it goes. Once the time comes to replace wearables, I will make the jump to 12s.

Also ordered a couple of Vapcell F12 batteries since I saw reference to those earlier in this thread. Not sure if that is a good price but it says "genuine" over there and Reddit confirmed its a reputable website.

Hi All
I'm a bike mechanic in Ireland, and in the last year I've built 5 customer bikes and 1 for me using eRX. And it's all been grand, couple wee hickups here are there, but overall very good, customers happy

For shipping reasons I buy without batteries which I source locally. The batteries I've been using are 14500 800mah un-protected, as the protected cells are too long to fit. Also capacites over 800mah are also too long to fit in the tube without forcing and bending it. I know to my cost, as the wee copper strip up the back of the pack is extremely fragile at the solder between the 2 batteries

Today a customer flatten his battery on a ride, when after re-charging its become apparent that the cells have been allowed to discharge below 30% and ruined them.

I'd presumed that the actually battery tube had a BMS at the top, now I'm not so sure.

Anyone else had issues with the batteries?

Also the manual states that a solid green LED on RD means the battery is fully charged. This isnt the case, if you open up the app you'll see it's charging and not 100%. This was the cause to the confusion for my customer, and the reason he didn't leave home with a full battery

Nice to hear since Ireland has the same wet climate like Belgium. No water ingress issues with the rear derailleur?

been very wet even for Ireland this winter. But no issues with water getting where it shouldn't

My ER9 shipped immediately but hit a snag. The package has been returned back to sender. I have never seen this happening before and I order a LOT. Bad news?

I wouldn’t lose sleep over this. Maybe the parcel got damaged or wasn’t properly packed. Good thing it happened in China still. Shouldn’t be too hard for the seller to sort it out. Did you order it with batteries? Customs issue maybe?

Did you buy the eR9 from LTWOO Official Store and you're in the US? I had this issue twice and ended up not getting the eR9 (my third). I was told it was because restricted item (battery), even though I ordered one without battery, so customs don't allow for shipment. It's a bummer. I was recommended to buy from other sellers to avoid this issue. It's kind of odd, since my first eR9 was from this store, though it was before they became AE Choice seller. Being shipped by Choice may have something to do with it.

I received my AliEx sale ER9 groupset while I was out of town last week. It took exactly 7 days to arrive from China to Southern California. Anyways, I examined all the hardware and everything looks good. Now I have to decide which road bike I'm going to install it on? It might have been easier if I just bought a new frame with the groupset! I'll report back later this week once I get it installed.
