Capable of higher discharge rates than NH2057 smart battery packs, the NH3057HD34 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.

With its’ 12A discharge capability, the NH3057 is ideally suited as a small “hot-swap” battery to hold up the device for a short period while the main battery is charged.

CH-series chargers are recommended for these batteries.

NH 3057 smart liIon batteries can be customized to meet unique specifications. SHA-1 secure handshake, custom label, custom firmware and additional performance options are available for OEM applications. Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.
