Can anyone put me onto a site that has info. on a jumper disabling a charging diode in a Hitec laser 4 transmitter.

Doing this, I'm told will let a better battery charger to be used. If anyone has this info. reply on this forum. thanks.

Hi rcsailor

The charging diode does not mean bad charging, but if you charge for too long the battery heats up and loses voltage, resulting in some loss of capacity. With NiMH batteries I believe if you let the battery cool down and then charge at a lower current for a while you can get the capacity back. I do this with my Hitec Eclipse Pro Car, monitoring the voltage display.

Modern "Delta peak" chargers look for the drop of voltage and stop charging at close to the max voltage or change to a trickle charge. I believe the charging diode prevents this system from reading the voltage accurately. Try the hitecrc site for information.

rcsailor ,
That 'charging diode' is there for a purpose. If you can accomplish that purpose by someother means, then removing/disabling the diode would not be a problem. (The purpose is to not connect the polarity backwards +=+ and -=-. Reverse that and the diode stops current flow before things mess up.) Don't know about you, but I can use all the 'help' I can get - lol.
