Just DO NOT let the voltage drop too low as lithium polymer packs are very intolerant of over-discharging.
The internal BMS should prevent such... (eliminating the need of buying a new battery if deep discharged like with conventional types...)
You'll however need a designated charger providing constant voltage... (got the small GENIUS 5, an NLP14 is fully charged within 40 minutes)
The BMS makes them also compatible with their boost packs, eyelet cable kit with connector avail...
(disclaimer: DO NOT try to boost any Lithium battery unless the MFG explicitly clears to do so...
NOCO does, the battery BMS and their GB-series boost pack's PCB communicate accordingly...)
This and the solid plastic spacers that click into place (not some adhesive foam blocks like other brands include) sold the deal for me...
With (new, freshly charged) AGM or gel types (tried both) the starter in my GF's V-2 cyl NT700 (EFI) frequently struggled to overcome TDC, sometimes requiring pushing the button 5~6 times...
Now it always cranks reliably at first attempt, promptly firing after 2 rotations...
(the V-4 of the ST1100 has less compression, but also there noticeable higher RPM at cranking and prompt firing...)
Yeah, using LiFePO4 on a classic MCs seems like a sacrilege, but they work really well...
