HV / High Energy Battery Packs

All New Li-NMC (Nickel Manganese Cobalt) cells provide more power, lighter weight, smaller size and has 25% more range than last year’s LiFePo4 chemistry.

With their high energy density, these batteries pack more power into a smaller and lighter package, making them ideal for use in electric vehicles, marine vessels, renewable energy systems, and other demanding applications where space and weight are at a premium.

These cells have been updated with even lower impedance. Lightweight High Quality 3.7V (nominal) Li-NMC cell. Pre-charge circuits is included in each battery string, isolation monitoring and SoC (state-of-charge) & SoH (state-of-health) calculations as well.

The batteries have a 8 to 12 year life expectancy depending on how well you treat them.

Smaller sized packs can be made on request.
