This shows how to make the internal charger terminate on lithiums. /g/ft817/files/ZL1THH/FT817-BatteryCircuits.pdf Read all the notes on the schematic. Note also that there is a lot

You can manually select full power at any voltage. On HF you can get 5W output at 9V. (At UHF the gain falls off at low voltages) So you can get full power off the NiMH? battery pack. The radio

Just reporting back: The rolled up tape idea didn't work for me -- tried many times with two different types of very sticky tape. However, the hot needle idea worked on the first

I'm thinking about making a simple rectangular battery tray out of either sheet metal or polycarbonate to go under the radio and attached with the lower cover screws. I know such a design would hold

Steve, ??? I used treatstock.com to find someone local with a 3d printer to print the case. It's a pretty good service. There is a learning curve as to what is involved with 3d printing. I would

From the graphs I've studied it seems like 9.0 volts is more realistic for a 100% discharge, both for the battery and for the radio. On that basis I would consider it to be ideal.? ?Ymmv, fwiw,

I had a question regarding this 3 cell Li-ION pack with the 3d printed chassis and cover. With a 12.4V peak, 11V nominal, and 8.25-7.5V cutoff voltage how well does this work with the 817? Does it

Ok Steve, I will slicing the .stl files and heat up the printer to try print it. We will see… Petr

I Have The Cells But do not have the space for a 3d printer Its a Shame That we no longer the large base of FT-817/818 users to get a entrepreneur to produce that "KIT", I Sure Would go for at leas 2

I did this with a wire and the power-up sequence remains the same -- LCD black, relay click on the filter board, powers off. I'll add something semi-permanent and see what the voltages look like. b

This is used on transmit - the limit current would probably be quite high >2A. I would not expect it to trigger at 0.5A even if it was active during RX as this is within the normal operating current
