Rad keeps their true/real technical specifications very tight. They will barely tell you the size of a nut! Really I wanted to get a HexLox system. They offered NO LIST, and I had to measure each one myself. A real PIA.
I tried to talk to someone just today on the support line. I forgot it was "noon in Seattle" and waited 35 minutes on my 1st hold. That person made the comment about my inquiry on an extra battery "as just strange" she said it twice! Then she denied saying it...After another 10 minute hold, I got some guy, he was even pissier. I'm a life long Iowan, I've done tier 1-5 IT Systems support. I'm a nice guy. The guy said they probably wouldn't even sell me a battery since they had my "non-specification" use of their equipment, in the call log. I asked for a Supervisor... CLICK! I asked for a call back from a sales supervisor, 5 hours.... we'll seee about tomorrow. Battery mounts are a defect replacement ONLY. Not an order-able item!
I've been working with these folks 2 years, 2 bikes, never a snort & getting 2 AH's in the same call I just wanna scream!
I got a battery from Gareth at Biggamebikes.com. He's in the UK, but batteries are DIRECT SHIPPED to you for free. Not the extra $100 Rad tacks on... He's good, smart, growing... email him, say Joel in Iowa sent you! He also sells the "magic" don't blow up your battery DATEX devices.
Batteries are a wild place to play. You don't need to be an EE, you just need to watch YouTubes and read articles. GOOD LUCK, keep in touch!
