Lithium Maintenance Charger

thingiverse

This is a versatile board designed for mounting multiple USB chargers and TP4056 boards along with relays (5V DPDT) to effectively isolate all components. I'm creating an 8S Lithium maintenance charger that charges each cell individually, and completely disconnects from the battery when power is turned off. The ideal print setting is without support, but if this isn't possible, it's best to avoid printing over the bottom of the Euro socket as this can be quite a challenge. You have the flexibility to adjust the direction of the charger boards either vertically or horizontally, depending on how you prefer to mount them. Installing a fan with a duct might be a suitable solution when mounting in the longitudinal direction.
