Serpent 440139 USB charger for Mini Spyder MT  [SER440139]

Compact USB charger for Mini Spyder MT

This Serpent 440139 USB charger is an RC-scale accessory intended for use with Mini Spyder MT vehicles. It provides a simple USB-powered option to replenish small battery packs between runs and during field sessions.

The unit's role is practical rather than performance-driven: it is meant to top up batteries for short-term use, help maintain readiness during practice sessions, and reduce the need to return to a workshop for every minor recharge. It is not a programmable charger and should be treated as a convenience device for on-site charging.

Installation is straightforward: connect the appropriate lead from the charger to the vehicle or battery pack, verify the connector and voltage compatibility, and power the charger from a standard USB source. Always confirm connector polarity and battery chemistry before connecting, and follow battery manufacturer guidance for safe charging.
