parallex model 7345

[rainbowdino]

Hi,
I have a Minnie winner 2003 that came with the parallex model 7345 converter. I heard lithium was just a swap and done with old age batteries so I bought two 100amp hour battleborns and after install noticed how long it takes to charge them. After research it seems my controller slowly charges lithium and may be bad for the longevity of them. Can anyone suggest a replacement for the inverter or point me to a post with a answer?
Thanks for any help in advance.

Toss your old out dated single stage convertor/charger for a new modern with 4 stage charging.

Is there a difference for which model to choose for lithium battery ! Would I benefit from upgrading to a 60 or 80 amp controller? Also thanks for the link very helpfull!

The newest models ending in 'VL' have the feature to charge the lithiums. https://www.bestconverter.com/4600-s...Kits_c_133.htm lI have no experience with Li, so no idea what kind of charge rate is required. Im still using wet cells. Although in my use, I wouldnt see any gains by going to a larger unit. Just dont have the high draw requirements. I stayed with 45A. The company is very knowledgable and answered my questions no problem. Maybe give them a holler.
When I removed my old unit, (which was still working, just wanted newer technology) the floor it was sitting on was burnt from the heat of the transformer. I highly recommend upgrading.
