Question on batteries!

Postby amm » 12 Aug 2017, 18:27

Hi,

I bought some gerbing glove liners and heated socks. I have seen all the information on here about batteries and wondered if you could advise what batteries would be best for these. I was hoping I could stick the batteries under my wheelchair, out the way.

The info on the gloves says:
Source: 12-volts DC
Current: 2.2 amps
Watts: 27 watts

and the socks info:

Source: 12V DC
Current: 1.4A / pair
Watts: 16.8W / pair

Any help would really be appreciated, as it would be nice to go out and for them to last 3 or 4 hours (If this is possible)

Thanks
amm

You could run them via an inverter from eBay directly from your wheelchairs charge connection. It would take 3.6A total, at 12V but under 2A from a 24v supply. So you would take 8Ah ftom your wheelcair in 4 hours. From the approx40 to 50 you have avaiilable.

Or an additional 16Ah 12V battery would be needed. But I suspect the spec is wrong. And it will be less or its thermostatic and so switches on/off. Because it seems like a lot of power.

An additional 14Ah is needed for a lead battery to work. To get 16Ah usable. So a 30Ah lead battery or bigger would be needed.

Or a 20Ah capable lithium. Eg FOUR of these in parallel would run for a littleover 4 hours: https://hobbyking.com/en_us/multistar-h ... -pack.html

I've got a Gerbing heated vest and socks. I wired in a 24 to 12 volt converter like this:
http://www.ebay.com/itm/DC-DC-Voltage-C ... SwhRxXKLHW
Directly to the battery with an inline fuse and a switch and ran the Gerbing plug under my arm rest. I also use the Gerbing controller otherwise I get too hot. Also, with the controller it does not use nearly as much electricity and I barley notice a range difference with 4 or 5 hours of use.
Works great and no separate battery to buy. It cost me about 20 bucks for the whole affair.

Is it possible to somehow use the xlr chart port on the controller?

On another battery note, I use eneloop AA/AAA's for some photography equipment, and I'm looking for a charger that can handle 8+ or charge 4 quickly.
Would these chargers be ok or would the ruin the batteries:

and

The chargers I dont know. We use a somewhat better one, but its overkill for a few AAs.

Charge port can provide up to 12A and at 24V as its connected directly to the battery on the chair. Thats 280 watts. Beyond that youwill damage something.

The Gerbing controller works on 12 volts so it wouldn't work with the XLR port
