Go with Dinotte's...or at least a high quality battery holder. In had a run time issue with one of my 200Ls and I contacted Dinotte. The first thing they asked was if I was using one of their battery holders, or a radio shack model. I was told that the cheaper battery holders don't have the efficiency that better quality models do. I thought this was a dubious claim at best, but I tried it anyway. Well guess what ... Run time issue solved! I don't understand the science behind the efficiency problem with cheap battery holders, but it seems to be a real issue. I have friends that are electrical gurus and they too have confirmed this as well. From then on I got my battery holders from either Dinotte, or Minute Man Electronics as recommended by my friends.
On the upside, I just converted over to Dinotte's Li Ion system. I still have two extra battery holders and a spare battery pouch. Contact me off line and you can have them
