1st production batch is being made.
Great deal on 30Q BT's from freeme in the OP here: https://budgetlightforum.com/t/-/46324. It's publicly posted so I'd say it's fair game.
But be warned: this is a one time use coupon code!! But $17.75 for 4 30Q BT's shipped is outstanding. I ordered 2 sets of 4 with this coupon code and got the 15% off of both sets.
I believe from my battery tests, VTC5A's solder tops did the best slightly, at first, but VTC6 solder tops don't drop as quick. Again, VTC6's are just slightly better than 30Q's relatively. GA's aren't bad, better runtimes because max amps is lower and capacity is higher.
