i bought a maxamps 2S lipo for my Tek18X ( Exotek super modded RC18T ) which needed a saddle pack to go over the center shaft. there is absolutly nothing i could say bad about the lipo saddle and a went a bough the same model in NIMH cuz it was such a good battery.
i charge them both with my ICE charger and they are just wonderful. thats my opinion on them for 1/18 scale, ive never had a bigger electric than 1/18 so thats all i can give for that but i dont see why it wouldnt be the same quality for 1/10 scale or 1/8 scale electrics as well
i also did get a letter thanking me for my purchase and they discounted me 10% for my first purchase through there online site. great CS and support if you ask me.
+1 for Maxamps!
