Are you able to make the battery pack photos into a gallery that can show larger versions? Nice work.
I love this – being able to have the battery pack, PA and rig all tied together and form a stand is awesome
Have you looked at a LiFePO4 solution for a better discharge curve with perhaps a cleaner TX ? Higher voltage to these rigs typically means cleaner output….
73 and looking forward to your pack
The prototype looks great! Any ETA on a production model?
Ed,
Any update on the battery pack? I want to purchase the TX-599 Stand and battery pack as a single purchase, so I’m waiting to hear from you that its(TX-599 battery pack) is ready for sale. Thanks.

I would like to purchase a battery back and Frame for TX-500. What do I need to do? I’m Ready! 73 DE K4KHO
I’m also interested in a battery pack. Like you, I’m quite cautious about LiPo batteries. But I have a handful of small ones for my drones.
Also, please recommend a balance charger.
Have you looked at Illumn.com as a battery source? I’ve bought from them for my flashlights and they seem to be a good source. My batteries are still going strong after a couple of years.
Battery Junction has high capacity high discharge LG 18650 button tops for about eight bucks each.
Requirements for the user:
1) user-brand new high quality/amperage 18650s
2) user-fully charged and balanced before pack installation
3) user-charges pack with certified 3S LiPO charge controller
Design goals:
1) pack -waterproof (1 foot of water for 1 minute)/(done)
2) pack-short circuit protected (done)
3) pack-low voltage/9V cut off (done)
4) pack-fully compatible with light saver max (testing)
-this is the purpose of the 3rd power pole connection
5) pack-internal BMS successfully handles the un-regulated (kinda) voltages generated by the light saver “12v” output (testing)
6) pack -output 9A to support continuous 50W of output from the TX-500 and PA500 in SSB at a 25% duty cycle for 30mins (testing)
Storage requirements for any period beyond 2 days:
1) user -each cell is discharged to the appropriate storage voltage
2) user -each cell is remove and stored in a fire safe container
3) user -the cells are stored at a safe distance from the TX/PA assembly (the batteries catching fire is fine, the TX and the PA catching fire is not)
