You can send in the power supply and I'll replace it for you. What type of battery are you charging and what settings are you using?

Thank you Tim Sandor
but if I send the power supply its will cost me from 15 to 30$ � to chip it to you and to take it back because I live in Kuwait and I have mill box in aramex

the settings for 989

battery elactrifly 3000mah 7 cell
type nimh--cell7--mah3000—amp3.00--6mv--temp130--trickle0.50

battery 4.4k 4400mah 6cell
type nimh—cell6—mah4400--amp4.00--7mv--temp130--trickle0.50

note: I thenk the 989 make battery hot because its charge the battery with Continuous amp there is no Cool-Off Time Delay

but the Triton2 have Safety features include cool-off time delay �

I sell my triton2 to my friend and I buy mrc 989

best regard

Wow, you're in Kuwait. Your profile says Springfield Gardens, NY. Try cutting the mv setting down to 5 mv for both batteries. This coud be why they get hot. What capacity are the charging up to?

Math error (capacity setting should be 3393 mah if want to shut off at 3800) I went the wrong way and cannot edit post.

never mind, old post.

If I cutting the mv setting down from 7mv to 5 mv , my battery 4.4k 4400mah its will charge only 2500 to 2900mah not full charg
i know there is no usb conaction but can i update the frameware for mrc989 to make Safety features cool-off time delay ???

I understand that the 989 needs a balancer for charging lipos. It did not come with one. Where is the best place to pick this up. I haven not used Lipos yet but plan on making the switch this year.

Since balancers and lipos are universal , then nearly any balancer will work as long as it has the correct connection and specs.

If you are going to plug it into the output of the 989 it is an easy job because the green connector can simply take bare wires. Match the output of the balancer to your specific battery and connection.

Tim@MRC

I've used the Equinox, Blinky, and the V-Balancer all with good results with the 989. But best bet would be to match the connector as guver has said.

Thanks guys. I haven't selected the lipos that I'm going to get so I was just doing the front end work. Guver, you seem to enjoy the charging more than the discharging

Great charger, not seen many others in the uk. While charging my lipo's last week, I found the green connector had become very hot, and when i checked the wires, they both snapped off due to the heat. I am struggling to repair it as I need a new connector, any ideas.

My idea has been to install a pair of female banana jacks like all my other chargers have. OR to solder a lead direct and just have a single or double lead coming out the side. I haven't ruined the green connector yet though , so it stays.

bozboy

Do you mean to solder the banana plugs to the charger or to what remains of the green plug?

Tim@MRC

What size LiPos are charging? You may be able to find a replacement plug at a good electronics supply company in the UK. You can try unsoldering the receptical for the green plug and then hard wiring a Deans (or other) plug to the board with 12-14 gauge wire.

I'm charging Orion 4800 2 cell lipo's. Would it not be better to see if I can get some replacement plugs, before I perform surgery on my charger. I'll try the Deans connector if all else fais. Thx

Tim@MRC

It would definitely be better to get a replacement plug if possible. Let me know if you have problems finding one and I'll see about sending one to you.

Tim

bozboy

Thanks, I'll try some hobby shops first, but Its not a popular charger over here.

Tim@MRC

It's not a common plug, so again, a good electronics supply company would probably be better.

My Feedback: (325)

What I was thinking was to use wires from board to female banana jacks. I haven't opened it up, maybe there's not enough room?

Tim@MRC

The holes are kind of close together for the pins on that recepticle, so soldering any wire to the board at that point would be difficult.

tim@MRC, why did you guys use that ugly green plug for? this is a great charger but why isent the output a regular female banana plug just like the rest of the chargers? I just bought this charger now I need to figure out whether or not I should hard wire another connecter or find more green plugs.

thank you.

Tim@MRC

Sorry for the delay, I was away on business again last week. The green output plug wasn’t my decision. Hopefully the next charger will have banana jacks.
