TP820CD Help
 

I recently purchased this charger and tried it out. I have a 25 amp power supply for it. However it will only charge my packs up to 8.20 volts. I set the mAh to 10,000 (packs are 6500 RC King) and charging at 8 amps. The voltage limit is set to 4.22 per cell and the capacity is set to 125%. Any ideas?

I sent ThunderPower an email yesterday. They will probably get back to me tomorrow. Anybody have a clue what's going on in the mean time?

Ok. Just kind of playig around with it, I have some older packs with dean's plugs. Those batteries charge just fine.I noticed that while charging my dean's pack, it was charging as CV. When using the inboard packs it read as CC.

I'm interested in the answer to this question myself- my TP1430 does exactly the same thing.:flaming:

So I've spoken with Thunder Power about it, they told me that it needed to be updated and recalibrate. They wanted me to send it in but I bought it on dirtoval.com so I have no receipt to show them. I did the update and recalibration myself and tried it one raceday with no issues.

Charging Problems
 

I have recently purchased the TP820CD dual port charger.
Problem...
Port 1 charges and balance perfectly.
Port 2 charges the lipo but with a balance deficit of .10. When i put the lipo into port 1. It shows that it is balanced properly.
My thoughts being that the charger is not reading the balance properly....

Any advice
