Product description

Overview

Drivers and pilots enjoy even more Smart advantages when using Spektrum™ Smart G2 30C LiPo batteries. New "Generation 2" features make these powerful LiPo packs even simpler and safer to use together with your Smart charger.

For example, Spektrum™ Smart G2 technology makes it much easier to balance charge your LiPo batteries. Balancing information travels through the unique data wire of each Smart G2 battery's innovative IC3® or IC5® connector. As a result, only a single connection is needed — no separate balance lead is required.

Smart G2 batteries come from the factory programmed to discharge automatically to a safe storage voltage of 3.90V after 72 hours of inactivity. The benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free. You can change the battery's Auto Storage settings based on your own preferences. G2 batteries also offer a storage discharge rate that's three times faster than the previous G1 Smart batteries.

Smart G2 30C soft-case LiPo packs also include thicker internal metal side plates. These plates improve heat dissipation and provide more protection for the cells against punctures during rough landings or in similar impact-prone situations.

As with other Smart batteries, you'll never have to set your own charging preferences for a Spektrum™ Smart G2 battery until you want to. When a Smart G2 LiPo battery is connected to a Spektrum™ Smart charger, its unique charging parameters and health information upload to the charger from the battery's integrated memory microchip. Through the charger you can view and set preferences such as charge rates, so all that's required to charge the pack is connecting it to your Smart charger. Smart technology takes care of the rest

Highly disappointed as I only got 3 uses out of this battery. I flew 3 times, well within the safe limit to keep it over 20%. But after the 4th charge when I put it in my plane, it says it hasn’t the sufficient power to fly.

    5.0 out of 5 stars CHARGER WARNING!
    Reviewed in the United States on October 9, 2024
    Verified Purchase
    It's mentioned in several places in this listing, but I still overlooked that these are G2 Batteries (my fault).. that means they're meant to work on G2 smart chargers.. G2 means they DO NOT HAVE BALANCE LEADS. I have 3 expensive balance chargers that I expected to use with this. Fortunately I had a small and inexpensive S150 G2 charger I'd forgotten about that does a surprisingly good job. I can't charge 4 at a time like i intended, but it works fairly well.

    The battery itself does a great job. It's the obvious upgrade next to the 600, which DOES have balance leads. Performance difference is proportional between them.. 30% more energy, offset by a weight increase so that it feels more like 15-18% longer runs on a light airframe.

    I believe the Blade 230s can fly even with a 1500mAh battery, and it would balance out the tail heaviness aswell.

    I’m using these packs with an Avian 15amp ESC in my FMS 800mm RC planes. The ESC has an IC2 connector, just like these packs. It’s a perfect, lightweight combo for those smaller planes. Getting 5 or 6 minutes of flight time. You don’t need an expensive Smart charger. Not having to worry about discharging packs with my busy life is really helpful. Highly recommend.
