I've seen these on ebay and wondered if anyone has any experience of them or anything similar, as my 520Mah iPowers aren't lasting very long in the Lectro UM450s I'm currently trialing, it may be I can't get a decent battery life from the UM450, and I have to try a different tx, but these might be worth a shot......

I expect their performance can only be 10-15% greater than the iPowers, which might not matter much. I also find performance between individual batteries to vary, which I can only determine to be chemistry and not build quality, so results may vary +/- even greater than that.

It's sure worth a try. Let us know your results.

We ordered some of the Hitech batteries to try them out and have gotten pretty good results. They ran a UM450 (a power hog) for a little over 5 hours before dying. That is a little over 525mAh which is dead on with their claim of 600 mAh (under a lighter load). The reason we got them is a Canadian broadcast network has been using some 9.6 Volt NiMh batteries that seem to be causing the um400's to fail. The batteries come off the charger at well over 12 Volts (!) and occasionally take out a phase locked loop. Seven out of 10 units have failed and we are concerned. A sister production at the same location is using standard batteries in ten units with zero failures. Of course, we've tried to exactly duplicate the failures here but can't make units fail (of course). Since the batteries are the only difference we are going to propose these Hitech batteries as a better solution as they will run more than twice as long and maybe not smoke the units. Meanwhile, I'd stay away from 8 cell 9.6 Volt NiMh's and try the Hitech's.

Or what about these Hitech 9V's? Rated at 600mAh

HITECH - the bummer is that the charger is only 2 bay.

I found a Hitech 10 bank charger here:

I wonder if it would work with the 600 mAh Hitech 9 volts. I can't seem to find any Hitech website to ask.

It is a NiMh charger,only. See where it says "don't use with any other battery types"? It will damage the battery and maybe you, if you use it with the LiPoly 600 mAh 9 Volts.

Is it possible to use the iPower charger for the HITECH's? I don't know how intelligent these chargers are, other than controlling the charging current and shutting off at a specific voltage.

No, the 4 bank ipower charger doesn't work as well. Does not seem to fully charge them, based on run time after charging.

Use lithium disposable batteries made by Dynamis they are 1300 mah!. They are great will run a plug lectrosonics tx at 100mW for 9 hours with phantom power on. Will run a COMTEK for a week!

Chris - <Use lithium disposable batteries>

Never. Why disposable? UNLESS it was a situation where i simply could not change batteries after 4 hours. iPower 520s do very well for 99% gigs.

Someone should find a way to get HITECH to make a 4-bay or even an 8-bay charger... I'll try as well.

I just bought these: http://www.ebay.com/itm/221002418393?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

It's a Hitech brand, so probably the same as Larry is mentioning. But for half the price... We'll see when they show up, keep you posted.

Looks like $10/apiece in quantities of 10:

My question is whether they would work in a NiMH charger. I'll try to check in with Thomas Distribution next week and see what they say about the Maha and Lion compatibility.
