I would like to utilize my GreenWorks 80voltbattery packs to supplement my home's UPS whenever the packs aren't needed in the lawn mower or other yard tools.
I have Qty.2 of the 2ah packs, and Qty.2 of the 4ah packs. Commonly I rotate the 2ah packsbetween the leaf blower and snow thrower, and the 4ah packs in the lawn mower.It is extremely uncommon any two packs are used simultaneously. I already have wide input (80v) to 12v and 24v DC-DC converters that I use with these packs to power things when camping, or when home utility power goes out. I have already made a connector that interfaces with the 80v battery pack socket (pos. neg. terminals only, not any of the charge status/balancing terminals)
My UPS (a TrippLite SU750XL 750VA 600W UPS Smart Online) has an internal 24V battery string (two 12v SLA type) and an external connector for another 24V battery string. Input to this connectorshould keep the UPS inverter working. Problem is it also acts as a 24VDC output for charging the battery.
Any suggestions/ideas/brainstorming on how I could do something like this...
80v pack(s) --> DC-DC converter --> 24VDC -->into UPS (but also blocking diodes??? so UPS could not force power back into the DC-DC converter?)
Other unknowns I'd like to explore...
- Can I combine the pos./neg. rails of multiple GreenWorks 80v packs for longer runtime? safely?
- Is it the Greenworks battery pack internal circuitry, oris it the tool, that shuts off the battery when it drops below a minimum safe voltage?
- Is this stupid / overly complicated ... to re-utilize the 80v packs when they are sitting idle 6+ days out of the week? (for example, I only mow the lawn once a week, the rest of the time they sit in the house)
