Re: Drill battery build help - Noobie seeking direction

Thanks for all the replies and help so far. I hooked up some alligator clips to the drill and the battery. Looks like the wire on the P- discharge port was not thick enough to handle the load. Now that I got that problem fixed, I had another question/problem to try and figure out. I noticed that hoo...

Re: Drill battery build help - Noobie seeking direction

Sorry for the lack of clarification. Yes, by "get nothing" I mean when I put the battery into the drill does not spin and when I put the battery on the charger, there is no recognition that the battery is on the charger (no blinking lights). I do measure the correct voltage of 14.8-15V fro...

Re: Drill battery build help - Noobie seeking direction

Thanks for the replies. That helped me get it wired up. It is now all wired, and I am getting 14.9-15V from the battery when measured...but when I put it in the drill...I get nothing??? I am I missing something? The NiCad battery says that it was a 14.4V battery??

Drill battery build help - Noobie seeking direction

I am starting to learn more about building batteries. For my first build, I thought I would swap out some old NiCad batteries for Lithium cells. I have a BMS for a 4S battery. I am looking for direction on how to attach the P+ and P- from diagram attached here, the P+ hookup seems pretty obvious, bu...

Re: Swap 4v Lead Acid for 18650 3.7 volt in camping lantern?

Thanks for the reply. Those are the same lines of thought I had. I will stick to charging them with my 18650 balance charger.

Swap 4v Lead Acid for 18650 3.7 volt in camping lantern?

I have a camping lantern which has a 4v 2ah lead acid battery. The lead acid battery is dead and I have swapped it out for two 18650 batteries in parallel. I maybe should not have done this since I don't know the answer to this question :-). The cables going to the connection to the battery are putt...

Battery wiring question

I have been reading up and researching how to connect 18650 cells in parallel and series. I understand how to do this in square or rectangular designs, but I don't know how it works in non square or rectangular designs. I am wanting to build my own dolphine case for my ebike and saw the cell configu...

Re: Can water bottle battery packs be wired up in parallel?

Thanks all for the response. I am now thinking of replacing the bullet connectors with XT 60 connectors. Seems like checking the polarity for the battery leads will be easy enough with a multi meter. Do you check the motor polarity the same way? Using a multimeter and just connect the multi meter le...

Re: Can water bottle battery packs be wired up in parallel?

@dogman dan, what gauge of cable should I look for on the Y connector? I do not have the XT 90 connectors that are on most ebikes, but my batteries and motors have 2 way moulded connectors (SAE) as shown in the pics. The combined parallel batteries would be 36V 23.2ah 2-way molded connector 1.jpg 2-...

Can water bottle battery packs be wired up in parallel?

I have two of these batteries: http://www.electricbicycleworld.com/li-3/. Would it be possible to wire them in parallel to get longer range? If so, does it just require combining the + to + and - to - connections coming out of the battery packs?

Re: Take apart two perfectly good 36V to make a 48V?

Thanks for all the replies. As I have thought about using both of the 36V 11.6ah batteries, the question came as to if they can me wired up in parallel? Does anyone know if this is possible?

Re: Take apart two perfectly good 36V to make a 48V?

It would be a 13s6p....i did not know about mixing used cells. Maybe it would not be worth to break open already working packs?

Take apart two perfectly good 36V to make a 48V?

I have two of these batteries: http://www.electricbicycleworld.com/li-3/ They are 36V 11.6ah using Panasonic (Cell Model NCR18650PD). Typical cell capacity is 2880mAh and minimum cell capacity is 2730mAh. I want to take the apart and use the cells to make a 48V 16.8ah battery. Would you advice again...

Re: Can this be fixed? Falco 500W stripped axle threads

I actually don't know what caused the problem. I purcahased this system used online as the description said "1 yr old, great working condition!" It was not until I received it that I saw the description was not accurate :-(. I have already arranged to return it for a full refund. I really ...

Can this be fixed? Falco 500W stripped axle threads

Hey all, before I send this motor back to the seller whom I bought it from (Item was sold as being in perfect working condition) I wanted to find out if it is fixable. The shaft/bolt of the Falco hub is badly stripped (See attached images). What are your guys thoughts, is this fixable? I know you ca...
