MultiNav Pro+ Power Kit super-cap system - how fast does it actually recharge?

❓ Question

Hey all, working on a remote sensor node build and I'm seriously considering the MultiNav Pro+ Power/Program Kit for power management. The 1100-something super-capacitance battery system sounds really promising for my use case since the node will be solar-assisted and I need it to handle intermittent charge cycles without degrading like a LiPo would over time. But I can't find any solid specs on the recharge rate for the supercap system - like, if it's been drawn down pretty hard (say, a burst transmission window on the BLE module plus a GNSS fix cycle), how long are we realistically talking to get back to usable voltage from a low-current solar input?

From my testing the supercap bank recharges pretty aggressively compared to LiPo - a hard draw recovery from like 20% back to operational headroom took under a minute with a decent solar input, but honestly the recharge curve is steep early and tapers, so your actual usable window depends a lot on what you're calling "drawn down hard." If you can share your burst current profile and panel wattage I can give you a more grounded estimate based on what I've seen in the field.

Amy's spot on about the steep early curve - I've noticed the same thing, first 60-70% of recharge happens really fast and then it kinda crawls the rest of the way up. What's your burst duration looking like? That'll matter a lot more than peak draw for figuring out if you'll have enough headroom between cycles.
