Title: fs-i6 1s li-ion(from old cellphone) battery mod question. Post by: sim_tcr on November 04, 2018, 04:51:58 PM Hello,
I have moded fs-i6 Tx to connect to a 1s li-ion(from old cellphone) battery. I tested flying with a micro and it works. Any one doing the same, know how to adjust the Tx battery voltage alarm? Note: Tx is running 14 channel rssi mod firmware v1.7.5 (http://"https://github.com/qba667/FlySkyI6/releases/tag/1.7.5") Thanks. Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question.

Slightly different route .. I connected a old cellphone battery to a voltage boost converter and adjusted the output voltage to 5v . Attaching a pic ...

Post by: sim_tcr on November 04, 2018, 09:05:21 PM I connected a old cellphone battery to a voltage boost converter and adjusted the output voltage to 5v . Were you using this DC to DC step up module (https://www.amazon.in/dp/B077WD9Z46/?coliid=IBWW32RW70AT2&colid=5UUZ9BF8W40M&psc=0&ref_=lv_ov_lig_dp_it)? So you have not adjusted the TX low voltage alarm threshold in TX settings? What mah li ion are you using? Are you seeing any improvements in battery life?

- no - 900 mah Li ion I get about 6 hrs of run time - about a month roughly . Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question. Post by: sim_tcr on November 04, 2018, 10:09:28 PM - yes Thank you. Ordered the dc-dc step up module. Will report back how much time I got.- no - 900 mah Li ion I get about 6 hrs of run time - about a month roughly . Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question.

Post by: sim_tcr on November 15, 2018, 01:27:11 PM A 900mah battery is smaller than a 1020 mah And the existing battery holder springs are removed.Also, it looks like, dc to dc module I used is bigger in dimention. Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question. Post by: sim_tcr on November 17, 2018, 10:04:28 AM Completely concealed the setup. Moved the dc to dc module to inside.
I can either put AAs or li-ion. Happy with it. Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question. Post by: sim_tcr on November 28, 2018, 12:37:44 PM Today while using the Tx, suddenly screen started flickering and tx voltage showed 6.08v (it was 5.08 till then) and immediately smoke from inside (I guess it was from dc to dc step up module kept inside tx).
Immediately disconnected everything and tested with normal AA battery. Everything is working. Tested dc to dc step up module separately and it is working too. Not sure what went wrong. Will use li-ion without dc to dc step up module. Title: Re: fs-i6 1s li-ion(from old cellphone) battery mod question. Post by: Mehul Anand on November 29, 2018, 07:27:52 PM Danger warning for me ...
