Can I use a 36v 1.8amp Li-ion charger to charge SLA batteries safely

I tried my 48 Volt LiFePO4 charger on my 48 volt pack and it got it up to 60 plus volts and it was still cranking in some amps. If you want to try I don't think any damage will occur if you monitor charge voltage and not exceed 2.3 v/c. What size battery are you trying to charge? 1.8 amperes is nice for a small pack but shy of proper charging on NPX-80 or larger battery pack. I have to try another LiFePO4 charger that just came back repaired for it gave out day one so I got a V power battery and charger last month or so. Just keep an eye on pack voltage. It is nor like charging a 36 volt pack with 48 or 60 volt charger. Just because it might go into current limit doesn't mean it is safe but 2.3 v/c to 2.35 or 2.4 is not too bad.

Well, don't worry you won't end up in a blast, but if you try for too long, then your battery might need replacement.
