Best battery

[Old Mechanic]

What's the best available battery today for an electric vehicle, in the 5K cost range?

In my opinion it would be headway lithium cells. I'm putting together a 9kwh 144v pack for well under 4k usd.

I ditto the Headways. I have them in several converted Motorcycles.

The biggest thing is to get them "happy". Work them in like you would a ICE motor. 50+ plus charges/discharges with light loads. Then...have fun!!!

Here I am having some fun with the Headways....

...I'd like to SEE a side-by-side comparison chart or table showing the PROS & CONS of all the currently usable batteries, ie: lead-acid, deep-cycle, Lithium, Nickel-hydride, etc.

Then we should start adding it to the wiki

This is just the thread I was looking for

Does anyone have an opinion on the US Battery 6 volt floodies? A pack of those would cost 25% less than Trojan floodies for the Jet Electrica 007 I'm buying.

Trojans are unfortunately going down the smithouse due to a change in management.

US batteries at the moment are better, and its too bad

Any one use Thundersky or have experience with them?

With the Headways how do you manage the batteries and charge them?
I was looking at the Engener batteries that are sold for plug in hybrids because they come with everything.
The Email they sent me included this information:

standard pack is 24V 80AH. You can use two packs in series and two strings in
parallel. Two BMS to monitor two strings. The normal discharge rate is 160A-320A in this
configuration. each 24V80AH pack is $800, BMS is $170, 15A charger is $150. The total for
this 80KWH pack would be 4 x 800 + 2 x 170 + 150 + $250SH = $3940

that seems like a nice deal
