Well, here goes another Chevy Volt battery install thread… Feel like we have this pretty well covered in other places but wanted to try to contribute back to the community as I go through my install.
My setup -
2000 GEM 4 seater
New T2 Controller
NEV Disk Brakes
I currently have some cheapo marine Duracell batteries installed that were great for about 9 months and then I just started getting crushed by voltage sag climbing the hills in my area. My goal is really hill climbing power and the ability to maintain 35 mph on the flats so I don’t get run over by traffic. I usually don’t go more than 10 miles without putting it on charge for the night.
I did the usually rookie mistake of replacing motor and batteries before going lithium. As I’ve learned through reading the posts, you should start with Lithium and then mess with other components after. About a year ago, I picked up 4x 48V 12S Chevy Volt batteries from Ebay and a Chargery Charger and BMS from @Inwo. Chalk it up to a number of things (our youngest is just about to turn 1 so we were dealing with that) and I’m just now getting around to dropping in the batteries.
First question for the group - What should I do for a charger?
Let me explain - the original owner put in 2 3 bank 12 volt battery chargers when the on-board charger crapped out. 1 is mounted under the dash and the other under the rear seat. I was thinking about leaving 2 wet cells in the front for weight and to power the accessories - light bar, radio etc. and then put the volt batteries under the rear seat. Should I just charge with the Chargery and not have an onboard charger? Should I get a Delta-Q with the Lithium profile and can I mount that under the seat without connecting it to the Controller? Best place to source a Delta-Q? Suggestions welcome
Next up, have to drill holes at the bottom of the battery for all-thread to hold the cells together and then I’ll saws-all off the water jackets. My plan for securing the batteries to the car was going to be to use an angled metal piece to marine starboard to the frame. Open to ideas though if any one has suggestions.
This will be a somewhat slow thread… I travel a ton for work and have a 4 and 1 year old… but I’ll try to document the process as I go. Appreciate the commentary and help along the way. And thank you to everyone that’s posted about their installs… I’ve read just about every lithium thread multiple times!!!
