Question 4

Is it designed to hold AA or AAA standard batteries?

Accepted Answer

In an emergency you can insert a spring or small magnets to fill out for any smaller batteries, but carefully.

Question 5

I need clarity re the symbols inside the compartment and how the batteries should be inserted. The right side has (+) and (-) inside circles PARALLEL and  - and + underneath with SERIES. The left side has only (+) and (-) in circles. If I have 2x 18650 batteries, how should I insert them to ensure correct polarity? In fact, a photo or diagram of the correct alignment would be appreciated.

Accepted Answer

It depends on whether you want your two cells to be in series or parallel. Very basic electronics:- parallel will give you around 3.7V, series will give you around 7.4v .If you want parallel, both cells are the same way
                                                                                                                    round, and both leads will measure 3.7V.If you want series - insert the cells 'head to tail' i.e. follow the colour coding of the wires!I hope you haven't destroyed any circuits, blown up any batteries, or started a fire!!!

Question 6

Does it fit in a Taranis Q X7 ????

Accepted Answer

It does not fit in Taranis QX7, just by a couple of mm. If you really want it, need to remove/cut them

Question 7

for which type is this holder 65 mm or 69 mmThanks for your answer

Accepted Answer

65mm Button head batteries fit nice and snug. 69 might fit with force, but is probably too large.

do you need  a capped 18650 for this

Accepted Answer

No
