Great Customer Support!

Bought this battery to use in a Blade 230 S Smart BnF heli. When the battery came in, it wouldn't charge with a Spektrum S120 charger that came with an RTF Hobbyzone Aeroscout. Contacted Horizon Hobby customer support, and they ended up sending a replacement battery, charge adapter cable and a new S155 charger (which costs twice as much as the S120!) since the S120 charger wasn't in stock. The S120 charger must have been the issue, because the original and the replacement batteries both work fine, and it is really helpful to be able to see the battery voltage right on the transmitter instead of just relying on a timer. The self-balancing and auto-discharging abilities are really nice too. My one gripe is that the battery doesn't have an IC3 connector which is way more common.

Great..!!

Great battery, works fantastic in my UMX A-10 and Ultrix 600mm, and with self balancing and auto discharge capabilities totally worth the price premium for me personally. Looking forward to using them in my UMX Citation when the adapter leads finally arrive. I hope HH designs more new UMX planes around this battery.

No Issues

The battery works as it should. Easy to charge with a smart charger. telemetry from the heli lets me know what voltage I have left in the battery. no concerns.
