Re: Operator's Interface: USB Chicklet + Battery

Hi Al, I'm gonna have to disagree with you on that one. I assemble 20 amphour NIMH packs for our DPV (dive propulsion vehicles) I have not had one issue with placing cells in parallel. The packs often sit unused for months, still no issue with self discharge other than the standard self discharge rate on NIMH. I perform minimal cell matching proir to assembly and still have had great results. I do the same with our Lion packs. We have had no instances of self discharge. In fact one technique used in cell matching is to place all of the cells in parallel and let them "Equalize". I have used this approach many times and have not had one single issue. Just my thoughts

See you at great lakes.
