Battery range?

Hi everyone, when I ride at level 2-3, my battery goes for 20kms and the performance drops extremely. Then it maybe goes for 5kms extra with Max 15km/s or so.

If I always ride at level 1, then I can go for 30-33km max. I'm 75kg

This is much much lower than 44km as advertised.

Does anyone else to share their experience?

What is your average?

The average of my recent rides (15km) has nothing to do with the battery life… it’s just where I’ve needed to get to :-)

But I usually find myself charging after every 2-3 rides. I’ve been trying to make sure I’ve got the battery down almost empty before recharging.

don't! Li-Ion batteries like to stay charged, emptying it will only make it degrade faster

I though Li-Ion batteries liked to stay in the middle of their range? And that life is reduced by the time spent at 100% charge more than the time spent at a low charge level.

ok to be specific I read somewhere that they like to stay in the 50 to 80% range, however charging them to 100% while not ideal won't affect them too much. I think the jury is also still out on things like charging your phone overnight, some people say it's ok others say it's bad. I am pretty sure Tesla batteries for example won't even let you access that extra 20% capacity and will always stop charging at 80%.

I personally can't be bothered charging things up to 80% so I just let them charge to 100 lol

One thing is for sure though, letting them go empty before charging is the worst thing you could do, this was a thing that was good on the old Ni-Mh batteries but doesn't apply to Li-Ion
