Description
A 21V 4Ah battery for the 12in Strider electric conversion kit, built as a capacity upgrade over the kit’s stock-equivalent 2.6Ah pack rather than a like-for-like replacement. Same voltage, more capacity, more ride time between charges.
This is a direct fit for the 12in kit’s existing battery compartment and connector. It pairs with the same 21V charger already used for the stock pack, no separate charger purchase required.
Whether you need this or the stock-equivalent 2.6Ah pack depends on whether you’re replacing a failed battery (either works) or specifically looking for more runtime (this pack is the better fit).
