[quote=Skipbreather;71007]Hi Marc-
Reasons are pretty straightforward. Has to do with how batteries die.
First is that alkaline batteries have a very gradual decline in output voltage. Nonrechargable lithiums are not all that different. You get enough warning before the start of the dive to not do something stupid like dive with a nearly flat battery. Rechargeable batteries, comparatively, fall off a cliff. They die rather abruptly. The consequences in terms of a dive would be starting w/ all looking good and then having handset die mid dive w/ little or no warning.
Other reason is that rechargeables do not hold a decent charge for a long time. In dive terms that would translate to needing to charge your battery pack before every series of dives. Stated another way: Just because you charged your cells immediately after your last dive a month ago does not mean there are enough electrons still stored for today’s dive.
I actually did use a rechargeable battery pack (my own design) w/ my Smithers-Jurgensen Gen 1 MK15 digital electronics in my previous rig. Thing ate 18 cell alkaline AA cell battery packs at the rate 1 per 20~25 hours!
There it made sense. In the Meg a 2 C cell lithium pack will easily last 1 to 2 YEARS. Very different story.
Hope this helps,

what do you mean in " in the Meg a 2 C cell lithium pack? which ic the best way to make the meg batteries. did anyone have an article of how to connect the 5 1.5 batteries in series? if yes, what equipment did you use? it would be good to see some pictures of the process as well.
Thanks for sharing information guys.
Safe diving,
Spyros
