This means that you can connect the Strobl to the LFP's and it won't harm them, but it also won't charge them to full capacity. It will help prolong their working capacity during flight.

go to ebay and search DC DC Boost

For less than $5 (including free shipping) you'll be on your way to fully charged batteries :c) Choose one with a suitable DC input range and output voltage (which is trim pot adjustable).

Note that a typical boost or buck boost regulator uses a high frequency switching circuit with fast rise and fall times - fair amount of harmonics. This can be mitigated by adding ferrites to the wiring.

These units work by trading current for voltage and vice versa.
