Where To Buy 30-A/H Li-Po Battery ?

[MEXICOWANDERER]

Shopping with this phartsmone is impossible. 33 WEBPAGE NOT AVAILABLE or Amazon is having problems try again later...

If I am looking at 500 dollars I'll have to kiss this off. But I'll need 100% of 30-amp hours. I have no idea if NiMH can endure 0% remaining discharges. 10 D cell TENERGY 14 amp hour rechargables cost a hundred dollars.

Weight is critical. Maybe eight pounds or so maximum. The Lifeline is going to have to stay home under my bed. The Respironics must be used with the humidifier anabled. No choice. Thank you

Cruise on up to California and pick them up right from the warehouse:

You'll need probably 40 amps of battery capacity to get 30 amps useful without killing the LI battery.

NIMH are fine with full discharge, better to leave 5 to 10% in them though. 300-400 cycles max with the NI MH in the type of conditions you mention. No idea on the weight...

The AGMs are going to throw a hissy-fit at 100% discharge

Hi rtz,

Mex needs 12 volts. So that works out to 19.2 pounds

That battery would be nice but you need 4 to get 12.8V, Thats $540 and the weight doesn't work either.
LiPo is the only way I can think of that would meet the weight requirement but the cost would be out of sight.

80 Ah and 4.8 lbs and $135 at the moment.

Or get this older model 100Ah for only $90 to play around with:

Or call and speak to Jack about the project and it's requirements:

You're talking about a Li-Fe-Po, right? If so, these are motorcycle starting batteries, and they are rated by the mfr as "ah equivilence" to a flooded battery under extreme draws. Essentially, they are selling you a 15ah-capacity battery that will perform under heavy loads like a 30ah would, regarding Peukert effect, and ONLY regarding Peukert effect.

My advice is, if you need 30ah, get two 15ah UPG AGMs, and fab up some quick-release jumpers.

Hi Mex,

I don't think you will find an 8 pound battery that does 30 amp-hours.
