7.5Ah $560 = $74.70/Ah
5.0Ah $298 = $58.60/Ah
4.0Ah $237 = $59.25/Ah
2.0Ah $178 = $89/Ah

I do not see how all of them are the same battery. Perhaps the 7.5Ah and the 5Ah are the Samsung 25R's then the 4.0Ah and the 2.0Ah are the Samsung 20R's.

Thanks for the idea! Thought I was going to have to buy a new battery.

Cool thread. I have used my 2 greenworks packs to power my ebikes.

I recently bought a Greenworks 60 volt lawn mower, and only when taking it out of the box did I see the range of other tools I could get that use the same battery. This was shortly after I got the idea to clear a bit less then a 1/4 mile of single track through my property. Long story short: I got the 16" chainsaw, and have worked the heck out of it for the last couple weeks. I went from "range anxiety" to realizing that by the time I wore a battery down, it was time for a break anyway!

NOT steady cutting, but intermittent use, it would have been a huge PITA to constantly be re starting a gas saw, and I am real pleased with the utility of the thing. Quiet of course also. No plans as yet to borrow the battery for any of my ebikes, but if my various batteries I currently (ha ha) use all took a crap tomorrow, I'd rig a way to use the Greenworks battery pretty quick I'm sure!

Excellent thread.

I have some of these EGO batteries and have been considering using them for ebike use for some time. The packs I have are 2.5 or 2.0 amp hours. The high current per battery concerns me, so I'm thinking I will use two of the 2.5AH packs in parallel. The 2.0 packs contain less capable cells and are probably not suitable for my ebike use, they would have to be limited to low power and would not have much range. I only have one of those anyway, I tried to stick to 2.5 packs but one tool kit only came with the 2.0 at the time.

3D printing a mount / connector for these batteries appears to be do-able. I would not call it easy since there are many features in the mount to fit, but once the design is tuned it will be easy to 3D print them.

Here's a rough cut at a seatpost dual EGO battery mount design (that I started yesterday, it is still under development). My thought is to run them in parallel to reduce battery heating, increase range, reduce current through the battery BMS and connectors, etc. We should be able to get good current from two in parallel without stress.

Not that' I'd buy them from a unknown source but I'm seeing the 7.5ah packs available from some random sellers for $230.00 to $250.00 vs. Home Depot's $358.75
Yuba Mundo w/BBSHD
Specialized Hard Rock w/9c clone, statoraid, hubsink
Trek Fuel 90 w/BBSHD
Above all run on 14s4p 52v li-ion
Ecobike folder 36v
Currie Flyer scooter 24v on 24ah of SLA

Every trip made with electric bike is one less car trip, saves money, no toxic fumes, less noise, less impact on roads.

I just saw that EGO has a snowblower, which requires two batteries at a minimum, it comes stock with dual 5.0-Ah packs. The motor is a belted 2000W unit (56V / 35A?). Sounds similar in size to the BBSHD.

The video stated that as long as one of the batteries was at least the 4.0-Ah pack, then it would run with any other EGO pack. Since they have high-amp 2.0-Ah packs for the string-trimmer, it "sounds like" the snowblower and its associated motor will run on 6.0-Ah's worth of EGO packs minimum. They clearly state that...the bigger the packs, the more torque the motor will put out.

On Ego's community forum they said they have a new dual battery 21" self-propelled plastic deck mower. Comes with 2 5Ah packs. $800 expensive though.

Two 5.0 AH packs are about $450, plus $50 charger, so the mower's about $300.

Folks should know that the power output terminals bypass the BMS on these batteries, so there's no individual cell protection or overcurrent protection, where a BMS equipped ebike pack will have both. The power tools communicate with the BMS on tool packs, which is something we may want to figure out how to do on our ebikes.

We are using an ego battery too. I opened mine up and connected the wires inside directly to the main power lead wires using connectors (no soldering or cutting wires) and then ran the wires out 2 small holes in the side. It was very simple and we can still use the ego charger. We put ours in a soft bag on the handlebars. We bought ours on ebay brand new and still in the packaging and there was a coupon at the time, so it came out to $28 for a new 2ah battery and used ego charger was $14.

Our battery seems to cut out completely at 42v. That is the lowest I have every gotten it to and the bike will not budge at that point, and our motor supposedly has a low voltage cutoff of 39v. It is a good battery for 4-5 miles although it seems a bit heavy for the amount of power it provides. So far we ridden over 200 miles on about 50 charges and it is still going strong :)

We've been using the 2.5Ah packs in our modified Razor RSF350 and MX350 bikes for racing. They have done very well so far and we all bought them for around $80-90 with charger from eBay or a reseller on Facebook of all places. We're using single batteries with 48V, 1000W controllers with a listed current draw of 27.5A. The 2.5 packs do VERY well in our races, rarely even getting warm. Races are around 3-5 minutes long and we can typically get 2 races out of a charge. Charge takes 45-55 minutes if you don't top-up between races. I couldn't be more happy with them for the application.

There's some race video:

I realize this thread has been going on awhile, but I thought I would share a very interesting video on how the EGO batteries might actually be built better (and potentially last longer. I am especially impressed with the built in heat management. I'm in the starting phase of building an electric dump cart for my wife, and at this point I'm looking at the technologies as well as pro/cons for different solutions.
I am NOT the maker of this video.

It does have a circuit board inside. My 48v motor supposedly has a 39v cutoff voltage but it is completely dead at 42v. Perhaps the cutoff voltage of the motor goes by the individual cell voltage and not the total voltage though, I am using a 52v battery and not a 48v and I undercharge it by 3v to get it to work with my motor. I'm sorry buy I am a noob when it comes to these ebike motors and batteries!

The motor doesn't know the cell voltages (usually.) So if you are seeing a cutoff due to low cell voltage it's almost certainly due to the BMS cutting the pack power.

Well I am very happy with my little 2ah ego battery. It seems to put out at least close to the 18a max my motor can handle and we normally get at least 4 miles out of a charge and it is quite hilly here. Not bad for a battery I bought new on Ebay for $26 and a $15 charger. They are easy to wire up too, just open the case and connect the 2 power wires to the 2 power wires inside, poke the wires out two holes in the back, and then add crimp on connectors to match the motor. These are great little batteries for newer riders starting off and would like to dip their toe before jumping all in.

I like what you have done there. Which controller are you using? Any issues with the voltage being too high for the controller or anything? Do you have to undercharge the battery? Interested in doing the same mod for my son's bike.

FYI. New Kobalt 80v 6ah battery available from Lowe's for $360.

https://www.lowes.com/pd/Kobalt-Kobalt- ... 1000679353

It's 20s (72v). 444 wHr. I'm guessing likely 2p using 30q cells. Seems interesting!

Milwaukee M18 (Owned by conglomerate TTI, willfuckee, Cryolby, Rigit)
18V 12Ah $350 canadian peso's - so basically 10S 12Ah for $700cdn peso's
$260 for you greenbacks.

https://endless-sphere.com/forums/viewt ... 14&t=99296

How does that compare with comparable 12Ah 21V (5S) batteries from the Homeless Despot?

While the Samsung 25R is as low as 1.90euro (lets round up to 2euro), their s/h charge is 30-40euro's.
2euro = 2.26usd
2euro = 3.04cdn peso's

5S is $15cdn for 5S1P 21V 2.5Ah
5S5P is 21V 12.5Ah for $75cdn and in 10S5P is $150cdn + $60cdn s/h = $210 for 10S5P 36V 12.5Ah
Plus 18650 holders and tabs.
Could use a soldering iron, ideally a tab welder which can be had for $50-$100.
Still a good viable option, everytime I run the #'s

Wait, what? That battery is $350 in the US and is only 18V? You'd need 3 of them in series. And then you'd have to worry about putting multiple BMSes in series, and the potential that you fry one when it trip, if it can't handle the open-circuit voltage.

The Kobalt battery is 20S2P for $360... 72V 6Ah = 432 wHr = 1.2 wHr / $

Milwaukee M18 : 18V x 12.5 Ah = 225 wHr = 225 / $350 = 0.64 wHr / $. Not so good!

Plus, you could probably use one of those Kobalt batteries by itself for a small eBike with limited range.
