Charging the Kenwood DMC-F5R , and Sharp Ms-100 ,200 etc

[Strungup]

I just Bought a Battery for my Kenwood and I dont have the proper power supply as many have expressed problems about charging theses units.

A Battery pack holding 4 NMHD Sanyo 2700 Batteries is connected to it and is charging quite beautifuly on the first try. NMHD 's are 1.2 volts , so 4 = 4.8 very close to our desired 5 Volts , also they are AC ripple free , none , zero no ripple whatsoever. Which is part of the charging problem , the AC here in Japan is 50hz , whereas in the US it is 60 hz , believe me it DOES make a difference.

SO with NO AC freq for the machine to reference it accepts the voltage coming in much more readily. The charge Meter has been going for an hour non stop and no glitch .

Make the Box ( Plastic with a Lid ,I will post pics tommorrow) and a proper sized cable for connection to the MD , 4 high capacity AA NMHD batteries , fully charged. When you get low plugin (works as both charger and power source) Hold the Stop button for two or three seconds and the charger should engage.

Update , "The morning after " I will reword this whole thing later and post pics , but it WORKED PERFECTLY , got a nice fat full battery mark with the unit unplugged , and the battery pack still shows full as well.

the thought , The SANYO 2700 NMHD 's run hot , on a full charge their voltage can be quite a bit higher than 1.2 , if I charge with my Solar panel setup they will register as a group 5.4 volts I have had 8 NMHD pack read at over 12 ( the voltage of the Panel direct) SO the Lithium in the MD is 1400 ma capacity 3.7 volts , Tha pack is almost if not a full 3 amps at 5 volts.

This gives an almost perfect charging pattern to the lithium , Lithiums like a fast start, slow finish , at a full pack the initial charge is a BIG 3 amps direct , as the Lithium charges and they get close to meeting in the middle the charge slows down because the batteries each are getting close to the same level of power . One Cant take anymore and cant give anymore , Equilibrium.

No overcharging , zip nada , ...clean conditioned charge , Which means that the Batts will last longer and charge better.

so now I have to make a modified cable for the RH1
