I too have to make sure that my 7.2v 3000 x 3(9000mah) packs(the HIGH DISCHARGE ones) are ALWAYS charged the day of the show, or as close as I can get to that for festies. Otherwise, like you folks have said, my 7.2v 9000mah NIMH packs go DEAD pretty quickly. However, as long as I use them within a few days of charging them, they hold a charge pretty well. Id say after charging them and letting them sit for around 3-4 days, they still have around a 90% charge
However, after a week or two, theyre pretty much KICKED and ready for anotehr charge.
The ebenfit f NIMH over Lion to me is the quicker charging times(I can recharge a 7.2v 3000mah NIMH battery in about 1 hour as long as its not DEAD) and their reliability. I have had (3) 7xx series lions DIE after 2 years. 2 of them died OUT OF THE BLUE within a month or 2 of purchasing them(one was GENUINE SONY and the other was a GENERIC SONY). It took 2 years for the 3rd one to die, but they give NO WARNINGS. You get to teh show and power the 722 on and BAM, NOTHING. I ALWAYS had to carry a backup lion w/ me
Now I ONLY have ONE (1) 6000mah+ Lion left, and 2 smaller mah capacity lions left. I MUCH RATHER prefer the NIMH's for their reliability and quicker charging times
I am DEFINITELY going to look into the low-discharge NIMH's for my 7.2v 7xx series setup tho
I would LOVE to have my batts charges last more than a frickin week
Does anyone know if they even make 7.2v 4500mah NIMH batts in a LOW-DISCHARGE version
I am moving up to the 7.2v 4500mah NIMH batts so I can cut WAY DOWN on weight. I now have 3 x 3000mah batts wired in parallel to give me 7.2v/9000mah 'packs', but with teh always changing market of batteries and electronics, I can now get (2) x 4500mah 7.2v NIMH batts to give me the SAME mah rating as the (3) batts Im using now
Id LOVE to cut down on one battery per 'pack' to help my back out
I should be able to afford the switch this fall for sure
It will also help recharging at festies FOR SURE, since Id only have to recharge 2 batteries instead of 3
And since I have (2) of those blue "Chun" Smart Chargers, it will work out PERFECTLY
