Default Help me charge TBM Li-ION batteries

I have a Mark II charger. I can set the mah to the 2600 that the pack is. Now, my question, is what amp do you guys charge these things???? I have heard .25 amp-2.6 amps, which is 1C. I have no need to push it that much... Keith

If you are talking about the Hobbico Quick Field Charger MKII, then I might be able to help. If you do not want to charge at 1C, then just turn the knob to the desired charge current. If you realy want to know the charge current, (because the knobs arent that accurate) youo could hook a volt/ammeter into the other ports. Like I said, I don't know which charger that is for sure, but I have the one I just mentioned, Hope this helps, Ken.

I just want to know what is a reasonable amp to charge them... TBM's website shows nothing that I can find about charge rate. There are no knobs, yes, the MKII Hobbico..

Thats ok... I will charge at like .75C . Thanks guys.... I am really hooked on the Fromeco Brand. I have installed 3 Fromeco Regulators and they are brilliant. All the way down to the neat blue LED, to the way you program them. The Li-Ions in the plane seem to last me longer. Nearly 2 seasons.... All my NiMh stuff was about used up after 1 full season. Thanks guys.

New regs have an LED??? Cool! I just got some but haven't used them yet.

All my stuff is Fromeco too... I bought some of their very first batts and regs and their first charger. Cool thing is... I don't call that often... maybe once a season... but Kurt still remembers me. Great customer service.

I just got the Ion Cube, fully loaded. What a wonderful gizmo... I love it to death and I'm on day 1.
