From the Facebook Group Aug 19, 2014 RF: Tonight's project, converting a 40A DieHard automotive battery charger to handle my SLA battery pack. Mainly adding some 10awg leads to an Anderson Power Pole socket to charge them in parallel. text/html 2025-02-10T20:04:04+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.powerracingseries.org/doku.php/cars:batteries:battery_chargers?rev=1739217844&do=diff Battery Chargers You will need to charge your batteries! At a typical Maker Faire you might get 10 Amp of 120 volt power to your pit. Keep that in mind when choosing a charger. The charger you choose will also have to work with the batteries you use. SLA are different than Lipo, etc. text/html 2025-02-10T20:04:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.powerracingseries.org/doku.php/cars:batteries:chevyvoltcells?rev=1739217845&do=diff Chevy Volt Batteries The Chevy Volt has batteries that split down (without a headache) into 7x 12s3p packs and 2x 6s3p packs. Lvl1 hackerspace, In Theory Racing, and Lazy gecko, to name a few, have raced with Volt batteries before. here is a link to a Lazy Gecko tear-down of a 12s pack to the cell-level: text/html 2025-02-10T20:04:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.powerracingseries.org/doku.php/cars:batteries:fordenergicells?rev=1739217845&do=diff Ford C-Max Energi Cells SAE Article Energy.gov Battery Test Results text/html 2025-02-10T20:04:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.powerracingseries.org/doku.php/cars:batteries:leafcells?rev=1739217845&do=diff Nissan Leaf Cells Leaf Cells (as they are called) are salvaged battery packs from the Nissan Leaf electric car. They are often found by PPPRS members who disassemble them into individual cells, each consisting of a 7.3 volt pack. Leaf Cells are a bit more complicated, and potentially more dangerous than the SLA batteries most teams started out with. text/html 2025-02-10T20:04:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.powerracingseries.org/doku.php/cars:batteries:volts?rev=1739217845&do=diff Volts SLA Batteries Most SLA (Sealed Lead Acid) batteries will be 12 volt batteries. If you are running at 24 volts you'll need two batteries, etcs It's pretty simple math. Some teams build “battery packs” consisting of multiple batteries connected to each other in series, with just two exposed connections which can make charging and swapping batteries a little easier.
