Battery RX 18650 Li-ion 3400mah 2s
The 3400mah Panasonic 2s battery is a great way to get a lot of mah and a solid HV system! We make these here in the USA by hand, by a US veteran, good stuff! You can charge them as LI-ION and if your charger does not have this, Lipo will work. For 100grams, you get a lot of power, enough to fly all day!
