How to charge your battery faster! (Multiple methods!)

Just remember that the faster you charge, the more heat is generated. Heat is one of the biggest causes of a cell degrading. You will get longer life/more charge cycles using slower charging.

I’ve been into ebikes less than 6 months, so I am on a information quest….this channel has been a treasure trove of quality information.
Make more videos please, I’m still hungry! Lol
Great job….again

[liscales]

Exactly what I needed, thanks. Have been looking to cut charging time for when I go bike-packing and will often need to grab a quick charge when the opportunity presents itself.

[raylivengood]

Glad to have this information confirmed.

I’m often tempted to charge using the amp “half” rule, but usually stick to 3-4 no mater the size battery over 10ah. My Cycle Satiator really warms up at 4amps, so the 40% sounds like a safe ceiling. I have a 48v 23ah battery that I’ve been tempted to charge at 5 amp+, but haven’t because of the stress to the charger and unknown ability of the battery BMS.

Thanks for the video !

Show us how to build a high power ebike charger with chardemo or type 2 ccs used for ev charging. These wall charges may be a little expensive but they output so much power thst we could tap into for those using our ebikes for the last mile logistics

Thanks! I always wondered why my 14.5 Ah (48V) battery charged in about two hours (from about 20%) when it said in the manual that it would typically take 4-5 hours (from 0%). The bike I have gets delivered with either one of the two: a 2A charger (regular), or a 5A (fast charger). I just realized that I have the fast charger 😄 I thought that maybe my battery was going bad, but guess not, lol.

Helpful info for my escooter too brother, thanks!

[christopherh]

Thank you for this info! Chargers are often overlooked but obviously important!

[CarlosSanchezMusicLife]

with my 48v 20Ah battery, i limit charging to 4Amps when the weather is cool, and 3Amps in the Summer.

always feel the charging wires near the battery input, and the side of the battery pack. if it's warm, back down the charging Amps.

you want to preserve the battery, but also want to avoid catastrophe.

[pascalbruyere]

Are there chargers that deliver more than 4-5 Amps anyway?
At some point the wire and plug become a problem of their own.
Also, isn’t the BMS limiting the current? In which case it would not help to get a more powerful power supply. By the way we call that a charger but in fact it is just a power supply, right? The ‘charger’ is the BMS, isn’t it?

[marthamryglod]

I have two 72v bikes and one 36v bike. They all have 2A chargers. I'd like to get an adjustable charger so I can speed charge to like 90% if need be. Any recommendations?

[apexer]

did you go to school for this? bro i love the videos. I just wanted to ride a bike to work and now I am stuck watching every single one of your videos even the ones that don't have to do with biking. Stay positive!

Hi Micah, I learned a lot from you. Thank you.

[MrZunzara]

i like to hear what i already know, means that my knowledge is correct.tnx

[RPRosen-kifk]

That was interesting. Micah, often times when I'm curious about something and I venture off YouTube and practise my Google-Fu, I'm offered articles from Electrek and about a third of the time ... you're the author. I thought that was pretty COOL.

[walleyehunter]

All ebike batteries should have a battery percentage and volt percentage gauge built on it .

[orson]

Micah, I do not understand what happened. I got a notice a while back that I was the winner of one of your books. I responded selecting the E-Bike Manifesto. I thought I did so in a timely manner. I never received the book and I did include my address when responding. I also emailed you through your channel and got no response. So, I figured I would post here and see what happens. That aside, this video was really informative. Thanks!

[rickrys]

Very helpful and clear presentation on charging. I use a DC power supply as a backup in case the charger fails . This unit can charge up to 10 amps. Nice to know I should throttle back a bit

[wkrupper]

Hey Micah, I always appreciate your videos!

[mikejf]

Haven’t seen you for a bit. Hope all is well.
