KiloVault has released two new 1.2-kWh lithium batteries. The 1200 HLX and 1200 CHLX can handle 80 A of continuous charging current and 100 A of continuous discharging current. Their smaller weight make them ideally suited for off-grid energy storage, among other applications.
These new 1.2-kWh models can be used in 12-V, 24-V or 48-V configurations and feature Bluetooth communication for easy health and performance monitoring. This flexibility – combined with a 5,000-cycle lifespan (at 80% depth of discharge) and low cost/kWh cycle – offers customers exceptional value for their energy storage needs. Even after 2,000 cycles at 100% depth of discharge, a 1200 HLX or 1200 CHLX battery will retain 80% or more of its original 1,200 watt-hour storage capacity.
KiloVault’s HLX and CHLX series batteries do not require active cooling, as their lithium iron phosphate (LFP) chemistry is less susceptible to thermal runaway. As they are lithium-based, these batteries do not require regular watering, desulphating or equalizing and do not produce dangerous off-gassing like lead-acid batteries do.
The 1200 CHLX features the same internal heating technology as KiloVault’s other CHLX batteries, which allows it to continue charging at subzero temperatures. As the ambient temperature dips below freezing (32°F/0°C), the charging current is rerouted through a heating film in the battery, allowing it to maintain an internal temperature above freezing. Once this is accomplished, the battery can resume normal charging.

Interesting, many of the Chinese LiFePO4 manufacturers are claiming their product has from 135Wh/kg up to 180Wh/kg, these seem to be about 95Wh/kg. Is this how one stays out of thermal runaway, keep the energy density low so heat build up doesn’t become a problem?
