Thanks....question: did you mean 10-12 AMPS??? I have to unpack my temp gun

Another question, the website had this for charging:

GP3300-Nexus Racing-19t/Stock High Power Competition

Step 1
2650mA 7.0A
Flex off

Step 2
2680mA 0.2A
Flex off

Step 3
4200mA 6A (for more punch, increase to 6.5)
Flex off
Temp 50
delta peak 09



What's with all the steps?

I had set the charger for the "peak setting" the instruction said use the CTX-D charging mode for NICAD'S.

Thanks for the help in advance.

My fault...I thought Arun had updated his site...Guess I'll have to get on to him!!

Charge at 6-7 amps with a peak cutt off of 10-15 to start with. Set the temp to around 47 degrees C to start (I had to go convert that over to F...HAHA). At the end of the charge check with your temp gun and see if its around 120 degrees F. If not increase the cutt off till it gets there. The temp cutt off is just a fail safe to keep a pack from overcharging.

Hope this helps

EA

No no...that's a GP3300 profile he pulled up. On the charging page, we recommend a linear charge for IB4200.

Carl, the step charging profiles worked very well on GP3300 and sometimes IB3800, but linear charging reigns supreme on the 4200's for sure!

is it safe to adjust the delta peak higher just so that the pack peaks at the near the ideal temp?

Yes, I recommend starting at 06 and bump it up if you aren't getting enough temperature. 6amp linear works well in a lot of situations.

What temps would you be looking at using a temp gun on the IB4200s and the GP4300?

Around 120F is the ideal temp for packs

Like A. Rhodes said, 120 deg (48-49 deg C) is an ideal peak temp...after charge, the battery temp will rise closer to 130 deg, which is spot on for IB's.

No problem, Carl .

Thanks...
