Hi Everyone, I've just joined the forum and hope to be able to contribute over time.

I have a quick question that I hope someone maybe able to answer.

In the May issue of Marine Modelling International magazine there is a great New Battery Charger featured by ERS that allows you to charge multiple battery packs at the same time - it appears to be designed mostly for RX batteries, but is something I've been desperate to get for regular 7.2v or 8.4v battery packs.

I have a number of fast electric boats that chew through 7.2v Battery packs in about 5 mins flat and take ages to charge up single handedly! I wondered if anybody knew of a charger that could charge 2 or more 7.2v or 8.4v battery packs simultaneously? In the 2000 to 3500mAh range.

thanks all.

Jamie

Thy the Pro Peak from Constellation Charger .
Charges up to 25 cells at once and will do NiCads, Ni-MH , Lipo , and Lead Acid cost's about ?89.00 ouch but it will do the job

Hi Jamie,

I know the "problem", with our six boats and a number of packs to be charged.
Here's how I "solved" it:

Previous to running my boats, I make sure all packs are charged (at home), usually the day before.
On "boatingday" the whole shebang is loaded in the car with an extra 12V lead acid battery (100Ah) and some chargers.

Once on the scene, prior to running the boats, the packs receive a booster charge, for better performance, with the charger (4A).

After the run the batteries are allowed to cool down while the whole circus starts again with the second set(s) of packs.

This allows us to run three heats with each boat during the day.

I got a couple of Gel-acid batteries, used in scootmobiles and such, these traction batteries are great for powering your charger on the waterfront, find a source that has "old" batteries, I got mine for a few bottles of softdrink...

Regards, Jan.

thanks guys, that's much appreciated.

I do have a 12v (off the cigar lighter) charger - but the max it charges at is 2A - which is ok, but not that quick.

I like the idea of the smaller 12v batteries - i guess similar to a motorbike battery etc!

I'll get a searching!!

Cheers,

Jamie

12v batteries "like a motor-bike battery" are exactly what you don't need. The 100A lead-acid batteries which Jan uses are often sold as "leisure" batteries and, in addition to powering scooters for the disabled, are also sold to provide the 12 volt power supply for caravans and mobile homes. They are big, heavy creatures! Be careful what you buy.

Theres always a never ending list of things to get in this hobby isn't there?!!
