Here are new 12v 3s1p Honeywell batteries with a bms that has an inline fuse, temperature probe, and molex connector. These packs are built right! Brand new, never used, in the original bag. Each battery comes with 3 Panasonic/Sanyo UR18650A. These are the good cells manufactured by Panasonic when they bought Sanyo, not the older style heaters.
Honeywell actually used to sell these for $39.99, but here at Battery Hookup today, just $1.99. Perfect to use the packs as is or salvage the cells from them.
