The Ni2020 is designed & built in the USA By Inspired Energy, Inc. You can buy any quantity from a single battery up to many thousands, all direct & built-to-order from Inspired Energy.

The Ni2020HD29 can be used in low temperature applications to provide improved (not full) performance to -20°C. Cell capacity will be reduced, as will the ability to deliver high currents - especially current spikes. Also fuel gauge accuracy & thermal measurement will still decline with decreasing temperature. For these reasons, the only way to assure yourself that the battery performs in your particular application to your satisfaction will be to perform exhaustive low temperature application testing under all anticipated environmental and operational conditions.

The Ni2020 Smart Li Ion battery can be customized to meet your needs. Maybe a label change to your corporate livery? Or a firmware modification to modify the smart battery data to suit your needs? Or perhaps you need the performance of the Ni2020 changing. Creating custom-hybrids of standard batteries is a part of Inspired Energy's established expertise.

Inspired Energy manufacturers all products to order. We sell direct to clients globally in quantities from 1 to  >50,000. We accept Credit cards for small orders & samples.
