# KeepYourTools

> KeepYourTools is a DBA of ReliaFarm LLC. The first product is a HyperTough 20V to Hart 20V battery adapter. It reuses the electronics (PCB) from old Hart packs so Hart 20V tools that expect pack communication can keep working after Hart batteries became hard to buy.

Hart tools were a Walmart lineup. Replacement Hart 20V packs are increasingly unavailable. KeepYourTools is not selling Hart batteries. It is building an adapter that accepts HyperTough 20V packs.

Many third-party Hart adapters only pass power on two conductors and warn that they work on simple/2-wire tools only. KeepYourTools harvests the original Hart pack PCB so the adapter can present the electronics Hart 20V tools expect.

Orders are not open yet. A pack trade-in (refund/credit after inspection, matched to the PayPal invoice) will launch with the store.
