ONYX RCR Battery Worlds Biggest For Sale

Ride as far as you can dream with our new aftermarket  amp hour Onyx battery. Available in 20s10p (50ah), 20s11p (55ah), 20s12p (60ah)

Featuring an ANT 300 amp peak smart BMS to monitor individual cell levels. The smart BMS also automatically balances your cells even when the pack is sitting within .006 thousand of a volt. This means the pack will last 2-3 times longer than a traditional battery with a generic BMS.

Each one of our batteries goes through a simulation discharge test at 100 amps to check for any cell defects. We use Grade A Samsung 50E cells.  

It ships with a stock Anderson connector; if you would prefer a different connector, just let us know in the order comments. 

It may be necessary to remove or grind a small 1×4 inch thin metal bracket at the rear of your battery tray to fit this battery.

Please take off your lid and measure the inside length of your particular battery tray and send to [email protected] or give us a call. Some battery lids may also have clearance issues that are easily resolved.

Dimensions: 15 (38mm) x 5.25 (13.5mm) x 7 (18mm) without BMS- 7.5 (19mm)

1 Year Warranty on all custom batteries
