Voltphreaks Battery 15% RL Group Buy Discount!
 

I'm cross posting this thread here in the Racing and DE Forum where weight really matters. https://rennlist.com/forums/parts-ma...l#post14713521

Voltphreaks lightweight batteries have been getting some great reviews here on Rennlist. The VPR96, for example, weighs only 5.25 lbs. with an impressive 940 cranking amps and is rated to -22 degrees! I reached out to Rennline to inquire about a group discount if we could put ten buyers together here on Rennlist. Rennline reached out to Voltphreaks and they have teamed up to offer a 15% discount if we can put together a group buy of 10 or more batteries. Any Voltphreaks battery would qualify and they would include SAE posts and upgraded Aluminum SAE adapters. Finding these batteries on sale is impossible, and I'm excited that Rennline has pulled this together for us.

If you're interested, please let me know by posting in the thread link above.

Thanks!

Be advised, some PCA Race Classes require a minimum weight of 10 pounds for batteries.

Never putting a Lithium anything in my race cars- I have seen too many catch on fire, or have other serious issues.

Good catch, but last I checked, the proposed Rules for 2017 were eliminating that restriction: https://rennlist.com/forums/racing-a...-comments.html
SPB:
1) Remove minimum weight for battery. The proponents see this as a relatively inexpensive way for cars, especially with heavy drivers, to get down to minimum weight. Costs for light weight batteries have fallen significantly from when these rules were first adopted.

Thanks for the feedback. Do you happen to know if any of these batteries you saw catch on fire were Voltphreaks?

Fair comment, however he technology on Lithium batteries has advanced significantly Lithium cobalt batteries can cause a chemical fire. Voltphreaks uses Lithium iron batteries which are not subject to the thermal runaway issues of a standard lithium-cobalt battery. Per Voltphreaks: "Although extremely rare, lithium-cobalt batteries, when abused, can combust in a chemical fire that cannot be put out with water or an extinguisher. Lithium-iron batteries, when abused, will vent but not combust, and if a lithium-iron battery does catch on fire, it can be extinguished, unlike a lithium-cobalt fire which burns until it is done." http://www.voltphreaks.com/technologylfp.php
