It's splitting hairs over the difference, but was just curious. https://lygte-info.dk/review/batteries2012/Sanyo NCR18650GA 3500mAh (Red) UK.html Measured capacity: 3345 mAh at 0.2A (12.275 Wh / 2946 Wh total) 3264 mAh at 1A (11.850 Wh) - more realistic for an EUC chill ride on Sherman Then the Sherman discharges the cells only down to 3.15V, so that's even less capacity. No 3500 mAh cell type, including Samsung 35E and LG MJ1 store 3500 mAh in tests, it's mostly a marketing name it looks like, not representative enough to get a sense of the actual capacity. Same with the 2700 Cells called 50 something, like the Samsung 50G: closer to 4800 mAh in practice, 50E does slightly better. I noticed that it's also most interesting to check out the Wh measured instead of mAh as the Wh value take into account voltage sag, therefore represents the actual amount of energy delivered best.

Patrick Robert Posted October 16, 2021 Posted October 16, 2021 One thing that I'm really impressed with on the Abrams is the 15A charging capability, officially stated by LeaperKim. I love long distance road-trips on my Sherman. On the road (like at home) I always charge at 10A, which is the recommended max by LeaperKim. I know some people charge at 13A, but I prefer to be extra careful with my V1. It's my baby. A full charge on the road takes me 2h 45m to reach 99.5V. I never balance on a charge stop, only at the end of the ride. Would take forever, and it's not necessary. I calculated that at 2700 Wh / 15A, that same full charge to 99.5V would take just over 1h 30m, almost twice as fast! So even though the Abrams might only give me 85% of the range of the Sherman (all else being equal, the Abrams goes down to 3.10V instead of 3.15V, and a torque motor could be more efficient), it charges in an hour and a half! Which is a decent stop by the way: it's the last hour of charging that seems to last forever on the Sherman! The Sherman lets me go 85 km on a mix of 40 and 55 km/h, and then I have to charge for 3h. I think I'd kind of prefer to stop every 72 km and charge for only an hour and a half! 3 Quote

Agreed, a 15A charge is very handy, and could be brilliant on long rides but I have to question just how big a 100v 15A charger will be. My 6A is big enough to carry as it is! That said, I find the Sherman will give me a nice (meaning not at 10mph) 100 mile ride with one charge stop of around 2 hours or 2x 1hr which I can kinda live with. Stopping twice during the day for an hour a time is OK with me, but I can appreciate that if you are doing a lot more than that in a day you could be sitting around a lot. 1 Quote

I always carry both 5A chargers, the J1772 adapter, an extension, and a 1.4 kg foldable high chair to recharge the rider as well. Bought a trek bag with hip support 🤣 It's actually not bad! I've done a few 1, 2 and 3 charge rides this summer. My best one was around Lac St-Jean, 245 km. On the Véloroute des bleuets (blueberries, common in that region of Quebec).

EMA Posted October 16, 2021 Posted October 16, 2021 22' wheels usually has a bit less range of the same battery on 19' it's nice to have a 22inch with 2700wh battery but i'm still wanna see this thing on a scale, if it will be into the 34-37kg range it will have a place in the market, otherwise i really don't see a reason to buy it Quote

(no fans required) I too can't understand no one reacting to the much improved build quality Veteran have made with the Abrams, especially in this area of cooling! King Song's S18 used this method of control board housing without the need for fans for cooling and is one of the coolest running wheels currently available, so this move bodes well for the Abrams. Photos courtesy of Bradley Michael Spence of eevee's via Facebook: This is definitely a huge step in the right direction and also an initial insight into what Veteran are describing as "Modular" construction for the Abrams!

Tawpie Posted October 17, 2021 Posted October 17, 2021 Die cast from the looks of it? That process has come a long way from when I used to get die cast toy cars for presents. Other than it being a bathtub, it sure looks pretty. I wonder how it handles altitude changes—remember the early Pelican cases that you couldn't get open if you went from Denver to LA? Quote
Planemo Posted October 17, 2021 Posted October 17, 2021 The other benefit is that it also seals the trolley handle - the only real area of ingress on the Sherman. 2 Quote
squirrel Posted October 17, 2021 Posted October 17, 2021 I agree, the more I see about the Abrams, the more I'm really stoked for it. I need a wheel I can ride in wet weather, T3 certainly doesn't fit that bill. My preorder has been in for a while, and I'm getting impatient! However I've never ridden a Monster so I'm a bit nervous about the size/weight, but it really looks like a great cruiser from where I sit. 2 Quote

Seems like a kluge to me... the cable bundle has to pass thru small openings in the shell, so there's not enough room for a nice inline connector (MT60, etc). So we're stuck with cheap crimp terminals and nuts that can rattle loose.

Future revisions get better connectors, perhaps? And what's going on with these GX16-5 pinouts? 2 pins for battery current and 3 pins for other things? Many secrets remain... Quote
Rawnei Posted October 19, 2021 Posted October 19, 2021 Hmm looks like the battery cables are soldered onto the board or are those some sort of bullet connectors? If soldered will be difficult to swap the board. 15 hours ago, RagingGrandpa said: And what's going on with these GX16-5 pinouts? 2 pins for battery current and 3 pins for other things? Many secrets remain... The smaller cables are probably for lights and such, they just go out the same opening. Quote
