Charger question
 
i searched and didn't find a definitive answer.

i just bought a new charger to use with my boat. when it asks you to set the threshold whats that mean(3mv-20mv)? I'm using a 6 cell NIMH 3600 pack

what should it be set at? I've never really dealt with good chargers before

any help?

if you really want to get techincal waht kind of pack is it? is it a cheap stick pack or a high quality matched cells, do you equaliise? but for 3600's you should go with 3mv"thumbsup"

another question are you discharging before you charge? otherwise leave at 3mv and dont worry about"thumbsup"

3mv is probably a tad bit low. Most likely won't even get warm there. You can start there but you will find that 5-7mv will be best.

You want the batt. warm at the end of the charge. Not hot, just warm.

No kidding Einstein. I don't see once where I say anything about the charging amps. He asked about the mv setting and thats what I said. You told him 3mv, and I said that 3 was a little low, may end up being 5 or 6. You don't know a definate number till you see what the pack likes best.

So if you wanna correct somebody, make sure you know what the hell you're talking about.

thanks scattman. the pack worked perfect set at 5mv.

Nimh peaks at about 140f. If they are not getting that hot you are not getting a full charge.

i was keeping an eye on them with my temp gun throughout the charging, they highest temp i got was like 132f. that should be good right?

do you even own a high end charger? do you even know what peak thresehold is? dont be a A$$ your talking charge rates and yes your right on those. and i was only recommending what my similar packs use. and vould i ask what charger your using exactly

TLTCrawlin 05-21-2007 08:05 PM

5-7mv is right, thats what I told him on AIM, and yes I sold him the charger, so im pretty sure im right on this one. I charge all my packs at 1.5-2.5amps on 5-7mv. The amps so low because more runtime then punch (punch goes down fast, so myswell go for runtime)


Ill be sending you a letter with the manuals/setup guide, I forgot to send with you, I found them yesterday. You want em?, if so pm me with ur addy.

JohnRobHolmes 05-21-2007 08:30 PM

132f is close enough if you dont care about a bit more runtime. If you want a higher voltage or fuller charge just bump up the mV a bit more.
