Breakout board MPPT (Maximum power point tracking) charger LT3652. With a breakout board users would be able to build robust chargers+battery packs that always will deliver. ( The only chargers that comes close is GoalZero and Genasun but both has severe limitations )

MPPT charger ( with function similar to a "Imax b6"..but simpler )

Charger fetures:
* Solar panel ( (6v), 12v, 24v )
* Thermoelectric generator
* DC adapter 12v ( + step up in order to behave as a Solar panel..)
* Programmable Charge Rate
* Programmable Float Voltage Up Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd Chemistries

Background:
If you expect to charge in cloudy days you sooner or later will prefer 12v at least 10-20watt. I measured 200mA from 21watt powerfilm (rollable) with a sky covered with clouds this summer in Sweden ( charging a GoalZero battery which seems to have MPPT alogrithm ) It' would be nice with a charger ready for SERIOUS action ... ( not just a toy )

I nice complement could be Thermoelectric generator combined with a wood gas stove
( copper rod through the stove connected to TEG )

LT3652
with jumpers select float voltage and max charge current ( I believe in "keep it simple stupid" equals reliable )
* MPPT
* Input Voltage Range: 4.95V to 32V
* Programmable Charge Rate Up to 2A
* Resistor Programmable Float Voltage Up to 14.4V Accommodates Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd Chemistries
