Powering a headlight and turn signals

Hello and Happy holidays!!..Have a small favor to ask...I need some advice on hot to go about powering a headlight and turns signals..The thing is I have bought motorcycle parts and I have installed them on my beach cruiser type bicycle..Now I was going to go with a ballistic battery as i Though they were the best, but i contacted them and they said it would not work, as their batteries are meant for starting and not a main power source..I have about a 14 mile bike ride coming home from work so I know I need something thats going to give me the proper amount of power to run these lights but have no idea what to get..and I cant seem to get the right person to help me...So hopefully i will get many answers from professional here!!..thank you for your time..

hey thanks for advise..but unfortunately I have lights already installed..the connectors hooked up..now just need the right battery..

sounds great man thanks!!!very helpful!!!

With all the good cycling lighting systems on the market, suprised you would take the time to retrofit a heavier system onto your bike. LED cycle lights are inexpensive, draw almost no power, and are light to carry with you on your bike. They are quite a bit better than lighting systems of a few years ago.

Thanks..yeah i know ..about led lights..i just could not find the right look out of all the lights..i wanted to go with a more retro 50s headlight..heres what im working with..unfortunately they put the wrong bracket on it and it sits a high right now nut will get tht fix..also would you know what kind of connector is that..need to find it so i can connect the female end to battery..Thank you..I still dont have it running yet!!!

LiPo model aircraft type battery.

Come in hundreds of different sizes and capacities.
Best place to look for them is Hobby King./

For 12 volts you will need a 3 series battery pack, as each cell is 4.2 volts maximum. Ideally do not drain below 3.0 volts per cell. even better to keep them up to about 3.5 volts per cell.

What sort of current are you going to draw? and what time span?

If your turn signal flasher can take it, you could go up to 4 series but that is then up to 16.8 volts.

For example

A pair of those wired in parallel (positive to positive, negative to negative) would give you a pack of 16 Ah. so if you were drawing 16 amps, that would last one hour...or 1 amp 16 hours...I am sure you get the picture.

Really world figures would mean that you would get a bit less than that, but that is about it.


If you look at those packs you will see there is also a set of small wires with a JST -XH connector. Ideally you would parallel those too,


Charging then becomes an issue...you need a balance charger.

Again , the site has hundreds of chargers...from small ones that will be ok for overnight recharging g..to bigger powerful ones that will charge at 2000W and one hour or less.

Something like this is an option

But we aware...lipo can be dangerous.....if not treated with respect. DO NOT LET cells drop below say 2 volts and then re charge them..well you can but be vigilant...
The packs can go out of balance...so of your 3 cells in series, one cell may eventually go down to zero volts...but if you are not charging using the balance charge function..then you are now putting g12 volts across 2 cells, not three...so your 'good ' cells will be taken up to 6 volts each..and then likely puff up , burst and emit flames..

Search YouTube for LiPo fire.


any way.

ask more about it if you need help


just let me know likely max mum current draw, and run time you would like
