How often do you do a full battery burn?

[Plummet]

Well down to below 10%

What's ya motor power, battery size too?

I'm not that often, Probably once every 2 months. Normally im down to around 50%.
Life gets in the way most of the time.

Bosch cvx 85nm 750wh battery.

 

[Funkeydunk]

Every ride, twice a week, Bosch 625wh, from 100 to 4% circa 30 miles 4200 feet of climbing

 

[Streddaz]

I don't regularly do a full burn, and apart from not being great for battery life if you do it all the time it's mainly a time constraint thing.
Accidently ran my Levo SL down to motor cutoff the other day (3%) when I had forgotten to charge it the night before after a full turbo commute to work the previous day, then the same the following day and then headed out for a trail ride and fortunately pretty much got the whole climb in before running it dry. All up 113km and 1,978m elevation.
I've done a couple of other fairly single rides where I have run it down to almost flat.

 

[cykelk]

Two or three per month for me. I like a good battery burner on the weekend but don’t always have the time. Normal weekday ride is a 50-70% pull. Fazua 60Nm 430Wh.

motor 85nm yammy , batt 500 , ride 3-7 times a week. Run bat below 10% every second to ride.

Ive only done it twice I think.. 68km with 1890m of climbing mix of sealed and off road and a full day at Craigeburn range 42.5km and 1530m all off road.

Bosch CX, 750wh powertube. I don't often go for 5+ hour rides hence not using a full battery much.

Excuse my ignorance, but what do you mean by "full battery burn"?

Normally I would define it as a ride where you charge the battery to 100% and ride till the battery reaches its low cutoff or runs flat completely drained to 0%.

Yep or close to it.

A full cheeseman E day would be epic.

 

[Dax]

Pretty much everytime I ride my FF Kenevo. Originally a 500w battery, now at 88%, so 440w

 

[Guyt]

My Orbea Rise is fairly new (1200 km on it), my average ride distance is somewhere around 25K, so I rarely drain more than 40% of my battery. Theoretically, I could recharge the battery every second ride, but I prefer to recharge every time, usually from 45 to 85%.

Correct me if I am wrong, but I think that E-MTBs battery are made of Lithium-Ion cells and, from what I read a bit everywhere, the smaller the charge gap is, the better is the longevity of the battery.

 

[Doomanic]

Pretty much every time. The closest decent riding to me is 45 miles away so I’m going to make the most of it.

 

[steve_sordy]

My last bike only had 370 W-hr, so I got it down to zero quite a few times. My current bike is 630w-hr and I have never had it below 30%. When I get back home if it is below 55%, I charge it up to 75-85% and leave it until the night before I go out again. Then I take it up to 100%.

 

[Plummet]

Nice, some wildly different responses.

Qudos to the full battery burn dudes every time. I'm usually too time poor to burn full. That takes me at least 3 yours. Usually i'm in the 1.5 to 2.5 hour riding bracket.

 

[2WheelsNot4]

I never have. Usually down to about 40%, maybe 30% before putting in a full charge..

Interested to know if this is a good thing or bad, though the bike is nearly 3 years old now and thats the way I've always done it.
Bosch performance cx gen 4 625wh

 

[Mikerb]

Bosch CX and 750w/h battery. I usually charge to 85% and on most ride discharge to 40% ......on one occasion that "reserve" was useful because on getting back to the van I found that my phone had dropped out of my waist pack so had to do the whole ride a gain to look for it..............unsuccessfully.............but a dog walker found it and took it home ironically just before I got to the spot where she found it!! so I got it back the following day.

 

[Bones]

About 6 times a year.
If you're miles from home then it gets hammered. Certainly not walking because it's got to 30%

I did a Bosch 500 (actually 480Wh) in 11 miles and 1 hour of Turbo Twattery. I was absolutely blown at the end.

 

[Kingerz]

I read the manual for the bike and do that since it's a solved issue. Panasonic say after 15 cycles or 3 months.

 

[Levo-Lon]

Never 540 w specialized levo 2019

Been down to 25% but I very rarely use anything above Eco..never bother with full power

 

[Mik3F]

I imagine I will come close at Ard Rock to doing a full cycle

I'm a minimum of 2 hours and full turbo mayhem. But i've learnt that turbo once up to speed is no faster than emtb, so can increase to 3 hours at full mayhem by flicking down the power levels particular for higher speed gravel sections where you are tapping on the speed limiter.

 

[Binhill1]

Rarely. Quite often down to 2 bars on levo though. Most times charged to 100 percent before a ride. Just short of 10,000 miles in just over five years battery has been amazing. It still shows 100 percent health . I'm due to give it the yearly test on eco using the original route I first tested it on .

When I added a light to my Rail, I hadn’t realized that enabling the feature meant that a certain percentage of battery was reserved for the lighting (EU requirement … like two hours worth, based on output of the lighting?). My 625wh Bosch battery got down to 11% and that was that. I had intentionally saved power to get up the hill to my house. No fun at all riding that beast up a hill w/o battery. I went back to Trek and asked them to dial back the wattage setting for the lighting and now it’ll give up the ghost at 4%. On long single-battery rides I’ll take the 625 down to 10%, else usually in the 20%’s.

My Rail 5 came with a 500wh battery and I bought a 625wh straight away. I’ve got a spare backpack designed to carry a battery and occasionally will carry the 500wh and go on the 6k+ ft ascent/40+ mile rides, no skimping on eMTB or Turbo if I get bored/lazy on climbs, and that’s the only times I‘ve drained the 625 (and determined the 4% cutoff).

 

[Roger20]

For optimum battery life the general recommendation for Li ion is 20% to 80%. Look at Tesla recommendation which is max 80% (unless the latest Li ion phosphate which is 100%). Going to 100% stresses the cells. Clearly if you need the absolute maximum range you will have to go outside the 20-80% range but a full charge should ideally be for as short a time as possible. Going below 20% or lower is supposedly equally detrimental to Long life.

I don't think Tesla superchargers will actually go beyond 80-85% (someone else can correct me if this is not the case) and as the charge gets closer to that level the speed/power reduces very considerably anyway.

 

[d3ftone]

Fully drain about 10% of the time. Below 20% battery probably 85% of the time. Generally using a 50/50 mixture of trail and boost. Shorter rides (1-1.5 hours) I just use boost. I'd just use boost on all my rides if I wasn't worried about draining the battery. This is with a 700-750wh battery, fairly draggy tires. I weigh about 190 lbs without gear. The drag on these things when they're fully dead is brutal, like riding with the brakes on.

 

[Evelhornet]

Almost everytime I ride, for me. I ride at BPW (pedal up only) usually at least once a week (lucky enough to live local and have a season pass) and want to get as many runs in as possible. I also have a second battery and on a good day can use the two batteries until the bike is less than 5% on each(Giant Reign e+0) Been doing this for last 2 years and both batteries are in excellent health.

 

[darwink1]

620 or 630? battery/ep8 (sc bullit ).

I usually have one or two bars left after a longer ride, 3 after a shorter ride. Our terrain is rocky, technical and undulating without any sustained mega climbs so I'm not draining half the battery on one climb like some. I also mostly ride in trail mode.

I would probably be good with a diet emtb but I enjoy full power too much and I'm not a featherweight.
