I would have bought a BMS also but I didn't see one with Bluetooth in your selections?

Could you investigate and add a quality bluetooth BMS option? I would have purchased that also even if it was a little more expensive than from China as I feel comfortable buying from u here in the USA.

Thnks, mike

Thanks Mike, we're looking into it but they are quite a bit more expensive and we've found that the demand is quite small compared to the simpler BMSs, meaning we might not have enough demand to justify stocking them yet.

Received my first v1.5 kit and constructed a 7s4p power pack for my E-Bike.  It was very easy (about 75 minutes) and well worth the expense of not having to weld or solder batteries.  Great invention....thank you.  I use a simple 8s hobby charger with a 12V power supply; therefore, a BMS was not necessary.  

how long does it take to get order delivered?
