Viper Lightweight Battery

[turbo800]

What is everyone running/ going to run for a lightweight battery?

I've looked into Ballistic EVO, Shorai LFX, Yuasa YTZ7S, and Earth X


I think I've narrowed it down to Shorai. I didn't care for the price tag about the EVO. I didn't like the idea of having to fill area around the battery for the Yuasa using a smaller case and only 130CCA. Less reviews about the Earth X batteries.

So I guess my question is, which of these 3 Shorai's would you pick, or is there something better?

LFX24L3-BS12 -> 24AH -> 360 CCA -> 3.6lbs -> $204

LFX27L3-BS12 -> 27AH -> 405CCA -> 3.85lbs -> $214

LFX36L3-BS12 -> 36AH -> 540CCA -> 4.81lbs -> $262


Stock Viper Yuasa YTX20HBS = 310 CCA and 7.8lbs, seems the Shorai 24 would have every bit of juice and the most weight savings (4.2lbs).

Stock Nytro Yuasa YTX20LBS = 270 CCA and 11.2lbs

Wow interesting! Looks like you CAN have your cake and eat it too. How does the reserve capacity compare?

I'd probably opt for the middle one. More beans with minimal price and not much more weight.

Skip the Shorai and go for something else. The Shorai requires a balancing charge everyone so often from a special charger and if you let it drain completely it will likely be toast. The earth x has balancing circuitry built in and will shut off if it goes below 10v.

I havr shorai three years no problems yet

I'm getting a Roll Over Valve kit from MtnViper. He also has the Shorai battery, and hasn't had any problems with it. He says it went all season being charged off sled power with out any issues. He moved it from his Nytro to his XF7000 when he changed sleds too...

I'll probably end up buy the "27" version, as it has the same dims as the stock battery.

This is the one I chose (probably overkill) nearly identical dimensions to the stock Viper Battery and has 4 top posts for mounting flexibility.

Like all Lithium batteries the operating range will always be skewed to warmer temps... but you just have to "energize" the battery with the ignition before turning over when it's super cold out.

Wot, what do you mean " energize the battery " . Turning the lights on or something like that.

That's one way... just turning the ignition switch from on to off a couple times does it too... Lithium batteries gain power as they are energized/warmed up.. unlike a lead acid that loses power as it's engaged. Should only need to do that when starting the first time in really cold temps.
