Bought the a Evolution Spektrum receiver 4235 five or six years ago along with 1500MPX LIPO batteries. These are new still in the box. What do in need to do to check battery condition, etc. so I can install them in my TOP RC FW190 that I am finally getting ready for construction? Thanks for any help.
charge them up. Then use a LiPo charger and connect it with the battery output. Discharge it to 6.0V. Then you see the capacity which was in the battery. If it is about 80% or more the battery is o.k.
