Gavin and Mako scooter drivers:
Are you interested in a NiMH battery pack for your scooters? I am envisioning a drop in replacement for the lead acid systems. The battery would be 24V 26 Ah, 26 lbs (you'll need to add a little lead to the Gavin to get it neutral).
The main benefits of this system would be:
1) Longer battery life. The pack would bring the battery life up from ~50 minutes to ~2 hours at full throttle on the Mako, similar gains on the Gavin.
2) Much longer battery life in the cold.
3) Longer cycle life - treat the batteries well and you'll get >5x the cycle life of a lead-acid battery. This helps make the packs more affordable.
These packs and smart chargers have been used for a while now on electric bikes, so the technology is pretty robust. I have used the packs quite a bit and I think they will be able to take rough handling far better than the plastic lead acid batteries currently used.
First guess at costs would be in the ~$800 range for the pack, and ~$75 for the charger. Let me know if you'd be interested in this system - if there is sufficient interest we could design and test the packs pretty quickly.
