They are much lighter, smaller, and have a more favorable voltage curve compared to lead-acid.
As soon as someone suggests a specific part number for a LiPo or LiFePO4 pack that meets the energy/power requirements AND is cost-comparable and readily available.

Re: Battery required by rule

The main problem with Li batteries is like you say, cost. The other is that only some are safe considering the beating our bots take. I think the good one is a LiFeP. Probably more expensive too.

Mostly I'd just as soon stick with what we have because of the investment we have in both batteries and chargers. I could see stocking up on batteries and chargers the first year being a kilobuck expense.

Also, even though we are only 4 years old, we've yet to build a bot that even comes close to running out of juice in one match.......

Here's to a great year!

Mike

Re: Battery required by rule

Last year we bought 4 batteries from AndyMark for free shipping to CMP in St. Louis. A couple of mentors from our team were going to volunteer, so we picked them up and drove them back. Don't know if AM is offering the same deal this year. I think they were bringing an otherwise empty truck to CMP so that they could bring a field back with them.
