Dimensions and weight of buddipole a123 batteries
« on: August 22, 2020, 01:47:50 PM »

I am trying to decide which of the a123 lithium batteries that buddipole sells to get.  I know the voltage and amps of the different buddipole batteries but I can’t find the dimensions or the weight of
the buddipole batteries.  If some one has this information I would greatly appreciate you sharing it with me.  Please include the battery
Model number so I can identify which battery the dimensions and weight belongs to
Thanking you in advance for your assistance

Hi,

Their page on each battery has a "specs" tab with that info.  Does it not show up on your screen?

Dear Mark
I just visited the buddipole website and I cannot find any spec tab
I am visiting using my smart phone
Plenty of description of the battery voltage and amp and use age curve but no physical dimensions or weight
You see a spec tab but I don’t.  Very odd  can you send me a link to the specs?

Hi,

Probably it's just an error in their website design (not organized well for cell phones).  I can copy and paste the specs in another message.

i like Buddipole products, but the prices and specs for the 'nanophosphate' (actually, lithium iron phosphate) batteries are 2X market and somewhat misleading... for example, the 2.5Ah battery is touted as:

While the pack will run 100w radios without any problem, the run time is limited to approximately 30 minutes at a full 100 watts output.

if i could buy a 2.5Ah battery that would power my 100W rig for 30 minutes at full output, i would think the battery would be in the DoD-contract markup price range (i.e., a $7,000 hammer)

i surmise that the web pages need a bit of editing...

just my $0.02

I have to agree fully with this comment.
Those prices seem awfully high for what you're getting.
A 2.5Ah battery won't even run a little FT-817 for very long at 5W output.

If you want to BUY LiFePO4 batteries with some decent run-time, look at either
Dakota Lithium, or Bioenno. You could save a bit more by building your own from
cells intended for e-bikes, like from Headway. But prices have come down enough
in the last couple of years, that the amount you'd save by building your own packs
(and don't forget to include a BMS board!) has really decreased.

I'm seriously considering replacing the 42Ah of AGM in my portable battery box
with a 40Ah LiFePO4 battery from either of the above. Dakota seems to have a
better warranty, but the Bioenno offerings would fit better into my existing box.
Prices from either vendor are pretty close to one another.

My reasoning for considering the replacement are twofold:
1) It would almost double my run time in the event I can't deploy solar panels
to keep them topped off or the weather is unfavorable to the use of solar panels, and
2) It would cut the weight of my portable battery box roughly in half.

Best of luck with whatever you decide to do!
