HT600/MT1000 Battery eliminator

Post by illini52 »

I'm looking for a battery eliminator for my fleet of HT600/MT1000s. Are the aftermarket ones found on Ebay worth the $$, or should I find another source?
Thanks

Probally not. Some are pure crap.

If you are into building your own look at KB0NLY's posts here on building one.

The ebay ones, ProStar and couple other no-name's, have not been very good in my experience with them.

I had one that i owned, and another guy that owned one sent me his to see i could repair it because according to him it kept resetting his radio.

Mine had enough current to run the radio but the voltage would drop rapidly under load. The other one had good voltage under load but not enough current to handle transmit. Whenever he went to transmit the radio would reset like turning the power off and on. At first i thought it was RF getting into the eliminator until i devised a test setup using an empty radio case from an HT600 with the eliminator on it and then test leads to the radio. On transmit the voltage was fairly steady, 9.7-9.9v, but i determined that it was barely capable of supplying 1.5 amp, a high power Genesis will easily pull 1.6-2 amps. Though it should normally be around 1.5-1.8. So the eliminator current would sag and the radio would reset.

I gutted both of them and rebuilt with a 10v 2.0a regulator, diode for reverse polarity protection, and a couple bypass caps to keep it clean. I have a few of them now without any problems and i'm building a new one to go with my Saber at 7.5v, but i might also go for one at 8v to simulate a fully charged battery.

And for the record, if you have a dead battery to cut open you can build one for $5 or less in parts.
