Amongst the general unavailability of components caused by the Supply Crisis, a near total absence of integrated circuits for rechargeable batteries has caused further delays. As with other components, a common response is to re-engineer. But, this is a customer-facing component, not a deeply internal one; and alternatives are nearly non-existent!
On the plus side, the extra time has allowed nice refinements to the size and shape of the enclosure. Once the PCB’s charging circuitry is completed, the M!nder will go on sale in Vancouver.
