The Shenzhen 12.8V LiFePO4 battery pack has a larger capacity and longer shelf life than the standard lead-acid battery of similar size, which is why we use it in some of our larger robot packages. It has 42Amp hours of capacity. It has a complete BMS (Battery Monitoring Circuit) for over/under voltage, cell equalization/balancing, overcurrent protection. All the benefits of LiFePO4 are present, such as stable chemistry, lightweight, high capacity, etc. The battery is in a rugged enclosure.

Each battery comes with one(1) 8 amp charger. Average recharge time is 5-6 hours from a complete drain.
