I started with an integrated rechargeable glo starter 1800mAh. works but lasts about 10 minutes of use. Then recharge takes 16 hours.

Then buy a more beefy one 2100mAh, after 16 hours charging produces a dull red glow for a hot plug so it's duff and I'm -£18 down.

Then buy a more beefy 3Ah with built in battery indicator meter use for 20 minutes then flat requires 16 hours for recharge.

Now, there are two ways to start a glow engine either you can try turn the engine over with a chicken stick until hell freezes over or you can use a 12 v starter, there are 3 to choose from JP, Hangar 9 or Align. for the former 2 you need a 12 V 7Ah lead acid battery and the align requires a 2s lipo 7.2V+ charger.

Now the JP burnt out in couple of days total crap £30 down the drain, next up is Hanger 9(£50) which I recommend-it works. next we need to sort out the glow starter, since we are using a 12V 7Ah lead acid battery already we need a glow start system to be powered of the 12V 7Ah these specialist 12 V starters are available for £13.50, just connect them across your 12V 7Ah battery and you are good to go.
