About this part

NB3037HD29 Smart Lithium-Ion Battery: Capable of higher discharge rates and lower temperature operation than NB3037 smart battery packs, the NB3037HD29 battery pack incorporates the standard features that designers and engineers have come to rely on for safety and function, such as SMbus, a pull tab for easy removal and on-pack LCD display for relative SOC indication. The NB3037 (2S1P) 7.2V lithium ion pack has tested as low as -30C and is ideally designed for use in compact and handheld devices. (Note, in cases of low temperature applications, we strongly recommend testing in your specific application). With 8A discharge capability, NB3037 batteries are ideally suited as a small hot-swap battery to hold up the device for a short period while the main battery is charged. Features: SMbus • Pull tab for easy removal • On-pack LCD Display for Relative SOC Indication Our expertise lies in creating customized battery hybrids that seamlessly integrate standard components to deliver optimal performance. NB3037HD29 Smart Li-ion battery customization options: SHA-1 secure handshake • Custom label • Custom Firmware • Additional performance options for OEM applications N-series chargers are recommended for these batteries.
