Robot Batteries and Battery Packs

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 an 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.

Before purchasing batteries, please review our Battery Terms.
