Gotta ask, anyone in the USA purchase one of these? Were you hit with customs charge?
I purchased 2 TB48s and 2 TB 47 packs and have swapped 3 so far and am in the process is recalibrating the top boards by fully discharging and recharging. It’s going stellar I’m seeing each battery restored to its original capacity after 2 3 cycles. I’ve found that the best process is soldering a balance lead to each cell of the new lithium pack and fully discharging it before swapping the top computer onto It. Details in this forum
Battery TB48 - Unbalanced Cells or Electronic Failure )
this way the computer accepts the new lithium every time with no issue. Before I was trying swapping the new packs with each cell at 3.8V and I was having issues with the computer rejecting it. Overall if you are confident in your soldering skills these are an amazing option.
I will say I was a dingus and shorted the connection between a few cells my first go around and had to do some monkey business soldering cells straight to the top board, but as long as you don’t do that the process is
1. Solder balance lead (you gotta make one out of a JST connector and spare wire) to each cell of the new lithium
2.solder positive and negative connection for a standard Lipo charger to the positive and negative wire of the new pack to connect to your standard Lipo charger
3. Plug into your standard Lipo charger and fully discharge each cell to 3.2V
4. unplug and un solder the balance connectors and charging connector
5. Open top of old battery and unplug BMS circuit then plug into new cell
6. Put back together and charge with OEM Inspire battery charger
7. Fully discharge and recharge 2-3 times (keep an eye on cell voltages not battery percentage running each cell to 3.2 while still in flight then land Immediately once 3.2 is reached)
8. Enjoy new batteries
