The R5 R-Series battery from JAG35, a brand associated with DIY battery and EV content creator Jehu Garcia, is a reclaimed 36V, 12.8Ah (460Wh) pack built from Panasonic NCR18650BD 18650 cells. It's listed at $75, discounted from a regular price of $125, and is aimed at DIY e-bike, e-scooter, and power-station expansion projects.
JAG35 is upfront that these are reclaimed e-scooter packs rather than new batteries, and that they may show cosmetic wear from storage. Several variants are offered depending on connector needs — bare cut cables, an added XT60 connector, or an added XT90 connector, with both "untested" and "tested" options — and buyers should note that not all variants are always in stock; the untested bare-cable and XT90-untested options were unavailable at the time of this review, while XT60 and tested XT90 variants remained purchasable.
The brand states the packs can serve as expansion batteries for several popular power stations (including certain EcoFlow and Bluetti models) when paired with the right connector adapter, and that two packs can be wired in series or parallel to increase voltage or capacity. JAG35 is explicit that these are sold for DIY and "second life" purposes, that untested units are sold as-is with no returns, and that actual cell voltage may be lower than the label states since the cells are reclaimed rather than new.
The listing specifically flags that New York State law restricts the sale and reconditioning of lithium-ion batteries for mobility devices that aren't UL 2271 certified, and advises New York residents to research applicable regulations before purchasing. Buyers anywhere should follow standard lithium-ion battery safety practices given the inherent risks of reclaimed cells.
