We currently offer a Smart Battery Upgrade on many of our batteries. This provides you with SOC(State of Charge)/SOH(State of Health) of your battery. We do not offer BMS units with in-flight data logging, cell balancing, or telemetry.  Many flight controllers offer these features. Adding advanced BMS features to the battery can become a failure point. Flight controllers with these features are more efficient than an internal BMS and allow you to keep the battery weight as light as possible. Our lithium battery chargers provide all the necessary charging and balancing features without the need for a built-in BMS. For custom battery solutions, contact our battery tech team by clicking here.
