Curator's pick: TK15 High Precision Battery Tester
Without a dedicated shunt-based tester like this, monitoring lithium capacity is mostly guesswork because the discharge curve is so flat. It provides the exact peace of mind you need to know you won't wake up to a dead fridge in the middle of a trip.
⚠ Worth knowing: These batteries lack internal heating elements, meaning you cannot safely charge them if the ambient temperature drops below freezing. If you're building a winter rig, you’ll need to factor in insulated housing or an external heating pad to prevent permanent cell damage.
