This is our Heavy Duty All-Terrain Robot platform with 42mm gear motors. Built to navigate through rough terrain and over small obstructions, this heavy duty robot is configurable. This item replaces TP-070-000, TP-071-000 and TP-170-000.
We sell a wide variety of batteries and battery packs from single AA batteries to 24V (20 Cell) 10000mAHr batteries. We carry NiMH (they do not have the memory issues common with NiCad battery packs). We also carry Sealed Lead Acid (SLA) batteries, LiFePO4 K2 Batteries, and Li-Ion Battery packs.
Of course we sell transformers to charge your batteries along with a automatic battery tenders that will monitor your batteries charging progress and stop charging when the battery reaches peak voltage. For chargers and transformers, follow this link.
We have a bunch of power supplies laying around. This is a bag of 3 randomly selected 9VDC power supplies (wall warts). 110VAC input. About 6 inches of wire with no ends. If you need a power supply (wall wart), you can't beat this deal.
