12v Power Pack

[gibbo500]

Hi there,

I have just purchased one of these for the bargain price of £18.

I was wondering will this be ok to run my Bravo 12 HP pump by connecting to the red and black crocodile clips?

Sorry if it is a "bone" question but i really dont want to bugger up a £95 pump.

As always info much appreciated.

All these units are a battery in a box with some leads to connect it to the outside world.

I use one for work, so when I end up on a boat in the depth of winter with flat batteries I can still do the job I went there for.

It works great on the Bravo Pump , I have the same power pack . I was sceptical about its power and quality for the bargain price but there is enough there to pump a large sib up more than once and it started a 2.4 engine with a dead battery .

I've had one of these for a bit now. Not needed to use it.
It says in the reat riviting read manual that the black must not be connected to the - Neg of the battery but to an earth some where on the engine. So Not sure if you can use it to power things?
Mine has a 12V cig lighter socket on it too.

Thats just a safety issue, if you jump any vehicle you always connect the earth to the body last because it will make a spark, you want that spark well away from a battery thats producing a stoichiometric hydrogen oxygen mix because its been heavily discharged when cranking.
if they blow up its usually very loud and spectacular, many people have lost eyes to plastic shrapnel. The acid is usually less injurous but can cause burns if not washed off fairly quickly.

Jesus!
So if I wanted to use it as an emergency charger (plugged into the mains) what do I do?
I only have a trickle charger besides the power pack.

Just dont make sparks near lead acid batteries! always connect the battery then turn on the charger, turn off the charger then disconnect the battery.
I used to gas weld buss bars onto lead acid batteries, you always leave the caps off for a few minutes so the lighter than air gas can escape before puting the flame near the cell.
now when a forklift battery goes thats a proper bang, and theyre usually under the drivers seat

I purchased a 12v Power Pack (in Cyprus) in 2004. It is a "GYSPack Auto" and cost me circa £30. Compared to some of the cheap, lightweight models readily available it is absolutely fantastic. It has sat without being charged for over 6 months and then easily started a 2.2l Diesel engine. It has been used on countless occasions and still "does the job". Well made and very compact, it is nearly as good as the commercial models available at £200+. IMHO it is an essential piece of equipment on a single engine/single battery rigged RIB, very cheap insurance.
