10 best tips for charging your ebike battery - avoid fires and prolong battery life

Top 10 ebike battery charging tips for safety and battery life. Prevent lithium battery fires, ebike, scooter, emoto battery fires.

Two additional tips one for batterylife and one for safety. For batterylife if your bike came with a so called rapid charger, but your battery and motor manufacturer makes a non rapid charger get the slower charger and it will prolong your battery life (shimano makes a 2A and a 4A charger). For safety if you happen to have a garage charge your bike in your garage or car port. Most building codes require fire safety provisions for garage and carports to be built into the structure to stand engine fires so if you charge in your garage especially unsupervised it is the safest place to do so.

One tip that is implicit in your routine is to give the battery chemistry time to settle before charging - even 30 minutes makes a difference. I also charge just under 100% wherever I can (it’s a game now 😊). My rides use 25-35% and I often nearly top them off just to avoid range anxiety or to be setup for a bonus ride💪 After 2.5yrs I’m at 120 full cycle charges on 700w Specialized turbo Levo and battery continues to read 100% health with Ride app (potentially less as apparently bike/app rounds up, shop app might report exact health %).

I always take the battery out of my bike to charge it. I live in a condo on the 16th floor and charge the battery close to the patio door. I also always charge it when I am awake. This bike is my commuter and charge it every two days. It is a Envo which is UL certified both bike and battery. Even if certified by every certification worldwide, I still will not trust it being left on its own.

the bluetooth/wifi smart plug is a good idea THANK YOU

Mine caught fire at my brothers house, his homeowners insurance covered it. The house was a total loss. Since then ive come to know that ebikes are just expensive toys that do not last. A small gas powered Honda is cheaper in the long run.

It would be nice if manufacturers build smarter chargers with a bluetooth connection that would allow us to set a countdown timer or max. % of charge for automatic cutoff. Great video by the way. Loved tip no. 1 ;)

Great video. I would suggest always make sure you hear the fan turn on in your battery charger. Mine came disconnected and it overheated. I connected it 2 years ago and it still works well. I believe many good batteries come with cheap chargers

[robertwaldren]

Good tips. I’d also suggest being very sure that any extension cords or timers you use are rated for the amount of power your charger draws. Also keep in mind that typical $1.50 household outlets aren’t meant for multiple hours of use at peak current, and they can really heat up. Consider replacing your outlet with an industrial/commercial grade unit.

We have 3 Specialized ebikes and always time them, always charge them to full and haven't ever had any problems

[marcoaguiar]

Put the left crank arm down when charging because it can fall down and hit the charger port of the bike and the cable of the charger and make a bad connection between bike and charger and could provoke a short circuit

I live in the rocky mountains of Colorado. My storage shed gets way below freezing at night. I way too many e-bikes to store inside my small house. So I came up with a solution that work's pretty good. I wrap the downtube with powered dog beds (never fold the dog bed when heated) and put Thinsulate insulation over that. Worked flawlessly last year.
I would say do this at your own risk, as doing it incorrectly could start a fire. But it keeps the battery warm and ready to use in the morning and protects against critical charging problems if the battery gets below freezing.
As Francis says, keeping the bike inside is best. Never charge your bike if the battery gets well below freezing. That could destroy the battery for good.

I generally charge my eMTB battery just before the ride to 100%. After the ride it remains generally to 10-40% with state of charge for few days or weeks till next ride. I also keep 20-25% state of charge over the winter for 3 months. I rarely discharge the battery to 0% on a ride. This happened 4 or 5 times in 2 years of use. Now the battery have 45 charging cycles and I do not feel a drop of autonomy. I store my bike with battery installed in a shady place on the balcony where the temperature is maxim 40 C degrees in the midday of summer and minimum 10 C degrees in winter.

Very helpful information. Thank you, E-MTBR.

[pascalropert]

An important thing in my opinion is to always let the battery rest for at least 15 minutes before recharging it, especially if it is hot and the battery has been used intensively. This applies to most domestic batteries anyway ;)

[hendrikmoons]

11. Always charge your batery at work.
12. Never charge the batery when it is atached to the bike.
If you do these, you get ZERO risks for fire/explosions at home and you only risk loosing your bateries.

[ramlinman]

I fulltime RV in my motorhome and I charge and store my battery in the oven...Just don't forget about your battery being in there and light the oven😂 but I feel safe storing in it in the oven.

[xx-thenightrider]

thanks for the video. don't charge inside a building. the fires are huge and it's too late to move it once they start.

[mikebenoit]

How do you go about getting a new battery for your E Bike

[trdlfbq]

Nice work sir, I'm getting my first ebike soon

[nijittwerdle]

What are those devices you use to hang your bikes on the wall?
