Lead Acid AGM Batteries
These powerful lead-acid AGM batteries were designed for use in motorcycles and other power-hungry applications like jet skies and snowmobiles. They do not contain liquid electrolyte so they are spill-proof and they can be used in any orientation.
Battery Charger for Lead Acid Batteries
The 3.5 Amp Charger does not require a separate power supply. It plugs right into your wall outlet. It uses a state-of-the-art three-stage charging cycle. It starts with a high-current fast charge until the battery voltage reaches 29.6. Then it charges at a constant 29.6V until the current drops below 500mA. Then it switches to a trickle charge and holds the battery at 27.6V. The charger can remain connected for long-term storage keeping the battery in a state of full charge.
This charger comes with a separate "XLR" charging port which you can mount directly on your robot for convenient plug-in charging.
