Can I charge this battery? Ryobi 40v 12ah

[sore knee bike ride]

The charger is a cheap Chinese charger rated for 42 volts and 1.5 amps it has a xt60u adapter. Only the positive and negative wires are attached.

I made an adapter that converts Ryobi tool port to xt60 u

I'm tempted to try plugging it in but I'm not sure.

You maybe flirting with trouble.
40v on the Ryobi battery is nominal and you need to know the exact voltage it should be charged to... though 42v is probably correct.
Being even 0.25v too high can make the battery unstable.

THIS is how a good battery can be a fire!

I have the factory charger, but it's a pita to unmount charge then remount. If I could charge thu the xt60 connector things would be much simpler

How could my idea start a fire?

And as far as voltages go, I'm pretty sure 24 - 60 volts will all work on the ebike.

Overcharging and charging with no protection.
The reason the tool battery has multiple pins is to allow the charger to protect it during a charge.

Can't touch this. Umpalumpa pants might help!

Fire:

So if I try to charge the positive and negative pins of the Ryobi battery with 42 volts at 1.5 amps:

-The battery might over charge
-Fire
-kickass and chew bubble gum
-wont the battery be smart enough to not overcharge
-And Bob won't be my uncle in this given scenario

Maybe there some funky anti battery charger module in the battery that senses China brand chargers?

Maybe the two middle pins deploy a charging password to the charger

Who knows though for sure

Ride safe and don't get a sore knee

Well actually I was thinking this was my best response to receive an answer.

Ide like to call Ryobi but I'm sure they would not relay this information. Not without being on the phone all day, talking to multiple departments, sending emails and being on hold.

I need this to do my job and this could make it easier.

What's your job that you have sore knees?

It could be a job to have sore knees, but what purpose that would serve? If anything you'd be shooting yourself in the foot.


So I was wondering If the outputs of the chargers are identical, then theoretically they should both charge the battery.

I was on the phone with Ryobi and they just wanted my email address and phone number. They also asked me the part number of the charger Wich I could not identify. I went through 2 departments and still dit no receive an answer.

Maybe somebody knows a battery guy?

Help is much appreciated.

Oh uh

Possible charging characteristics

-A variable current/voltage input
-a pulsing current into the battery?
-division of the charging input which is divided amongst the cells and only the Ryobi charger can perform(the Ryobi charger only has two pins)

This is the sort of buffoonery that'll bring on regulations. Why ever would a tool maker be interested in having their battery and warranty covered for use the battery wasn't sold or designed for?

That said, there are quite a few fellas on endless_sphere using tool batteries and may have better answers.

"Buffoonery" is the perfect word for this charging boondogle. Once we get past that, how about we add possibly incredibly dangerous ..

On the warning label, they should put:

"Do not barbeque the battery"

Protection circuitry for power tool batteries & chargers can vary with the manufacturer and is often proprietary. The various BMS functions can be split between the battery, charger and even the power tool. You need to fully understand how these functions work for your Riobi battery before experimenting.

I often use power tool batteries on my bikes. I take an OEM charger as well as the bike battery charger with me when I travel. OEM tool battery chargers are fairly cheap and worth the price. I have several around anyway for charging tools. I just take one with me when I go. Yeah, carrying two chargers around is a pain but, IMO, it's worth it for the added degree of safety. There is also the advantage of being able to charge both batteries at the same time.

Alright, so how many "8-10 word explanations" are there

To fully understand the solution to my problem?

If there are 10 explanations

I request some of them, if that's okay

What's your job that you have sore knees?

We experienced heavy flight turbulence over Texas, then it suddenly stopped. And the flight attendant emerged from the cockpit with carpet indentations on her knees while holding a napkin.

Air disaster averted.

 

[sore knee bike ride]

Okay, I appreciate both of those responses. Thank you.

So for demonstration sake, let's assume the flight attendant is the battery and the napkin is the charger. I would think turbulence would cause both the flight attendant and the napkin to be in disarray.
While what ever she was doing in the cockpit was happening let's say being charged by the 42 volts napkin charger, the turbulence represents the wrong charger.

So

If I were to use a xt60 charger on the ryobi battery would there be some kind of turbulence that would prevent the battery from charging? I was trying to figure out what this had to do with my question.
