I purchased some inexpensive Chinese Li-ion cells on Ebay to make up battery packs. They have protection PCBs installed. They worked quite well and are still going strong.
I also purchased a 14.8v 5000ma Li-ion pack from a reputable US seller. It failed after what I consider a short time. I found two defective cells after inspection.
Batteries can be very difficult to deal with. Sometimes you have to pay your money and hope for the best.
I think a good quality charger will go a long way to keeping batteries healthy.
If he has 3 5200ma batteries in series, they will still have 5200ma capacity.
Putting them is series will not reduce the 5200 ma capacity.
The voltage will be increased, but the ma capacity will not change.

Here is an example of batteries in series:
Series Connection
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.

Adding cells in a string increases the voltage; the capacity remains the same. Courtesy of Cadex
With the winter finally over in the Northeast, I am looking to order some Split Jaw rail clamps (stainless). I see RLD shows them in stock. I never ordered from them any feedback about them would be appreciated. Or any other place to order from.
If I remember right you did get a response from a Dan .. He works for Train-li .....
Dan? He works for Trainli? I guess he forgot to mention that. I don't know why unless he didn't want to get beat up for Trainli selling this bender without any instructions or paperwork of any kind.
They have been supplying this bender for quite awhile. It seems like they have had more than enough time to come up with something.
I received a lot of suggestions from several people on another forum. Most of them have been using it and surviving on a wing and a prayer.
Maybe I was able to buy mine because the seller was unable to use it without some instructions.
I still have not had a reply from Trainli at the email address I sent my request for help to. I would want my customers to be completely satisfied with my product and provide any assistance I could.
Too many companies don't realize how far a little help can go.
Ray does everything and anything he can to help his customers.
Preval has been around a long time. Years ago I used a similar sprayer from Badger. Canned air gets expensive if you do any amount of spaying. I was spraying model airplanes.
I finally bought an inexpensive air compressor and air brush for less than $100. I am sure glad I did. You can do nice painting and weathering with an air brush.
