Default what happened to my apache 2500 charger

I bought a apache 2500 charger from hobby lobby at the e-fly in here in Memphis, TN about 3 months ago. I have charge li-pos with it less than 20 times. I am trying to recharge my lipos and the green power light comes on. all that I get is the charge/error light just blinks. It starts blinking as soon as I connect the charger to the lipo. all I have is 3 cell lipos. My lipos show that I h have 10.96volts and the other shows 11.5 volts under 1/2 amp load.

I check the output of my power supply and it shows it putting out 13.2volts. I tried using my riding lawn mower battery, it shows by a volt meter it has 13.6 volts. I tried my field box battery is showing 12.8volts, and I tried my truck battery. So I know its not input power.

so what can be wrong with my batterys or charger.

If both the little clips (# cells and charge rate) are in the right places and making contact I bet its the charger gone bad. Several of them in use around here but none have given any problems. Been using mine for about a year, several times per week.

There is nothing wrong with the charger.
What it is telling you is that the cells in you LIPO Packs are out of balance.
In other words, 1 cell is not accepting the same amount of charge as the other(s)
For example, 1 cell is only accepting say 3.5 volts and the other( s) 3.7volts.
The Apache is a sensetive charger and will detect this and refuse to charge the pack. This is a safety default built into the charger.
I have been through this before a couple of times with Polyquest packs.
How to fix?
I had to use a different charger ( a Platinum Ex) and charge up each cell in the pack individually.
Then do a combo discharge and a combo recharge.
This fixed the problem o.k. and the packs are back in action and now charge up quite ok on the Apache.
Good luck

Default RE: what happened to my apache 2500 charger

I forgot to mention that on saturday, I took it to the field, and hooked my batteries up to a friends apache 2500 and it started charging them instantly. I tried each of my batteries on 2 differant charges w/ no problems. But when I hooked the batteries up to my charger all it does is set there and blink.

well that good for the charger for the safety feature. So now I still have to go out and buy or borrow a triton, which nobody is going to let me borrow their charger for a few days. To fix the problem of my li-pos being out fo balance that have less than 3 charges a piece on them. If I would have know that I would have bought the triton to begin with.

I do appreciate the help.

Way to go Hobby Lobby. I called hobbylobby and told them what was going on a a tuesday w/ the charger on Tuesday May 23. They told me to send it in, and they would look at it. I mailed in in on Wednesday may 25. I called them the following wednesday, just to make sure they got it. And they said they mailed me a new charger out on May 26. Even before they got my original charger back. They said I would have the replacement charger in a few days. So I got my replacement charger on friday June 3.

Way to go Hobby lobby. You defefintely exceeded my expectations w/ great customer service. You replaced a defective charger what was about 20-30 days out of warranty. and mailed me a new charger before you got my old one. I don' t know of anybody else that would do that. I will definefitly recommend and will buy from again.
