My flooded Gem sat for 5 months before I could get to it’s rebuild. In that time the new lead under dash battery went dead. Well that is just unacceptable. No bms to protect my $30 lead battery, well we will fix that. Plus I’m LG so the fact I had a LEAD battery in my Gem was blasphemy. So I ordered a lithium replacement. For the fun of it decided to try a small one and see how it works. This is a 6ah lfp from Amazon. $23. cheaper than the lead replacement. This is mini me. guessing it weighs maybe 1 pound? ![PXL_20230319_175301821](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/f/f761bf55c289b2c5667eb35a73cc844847512e3f.jpeg) ![PXL_20230319_205650349](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/4/4640e8dd80faa25e1ebbf1493e8c7206c55eca62.jpeg) ---

What are you going to do with all that extra room? Is it protected by a mini sized BMS too? ---

And the Gem is 9lbs lighter! More range. Yes it has a BMS, but no Bluetooth. ☹ ---

But… stock voltage and only 6Ah? Seems so uncharacteristic… ---

Beat me to lithium, but my idea is different. Use lithion 3s. That way the inexpensive plug-in 72- 12v converter will work. Lots of the cheap 12v packs on ebay are 3s. And not actually 12v nominal. ---

I think the stock 12v converter is just under 14v. if so, too high for a nmc 3s setup. Where you thinking changing to a different converter? ---

Yes, the cheap 80v converters are 12.4v. Plug in. The 13.8 are always back ordered. The hv conversion guys need them. Also it is safer with a 65v battery. New converter is 36v to 106v input or such. Totally universal. @djgabriel2004 ---

36v to 106v wow I love it. Dave do you know if they come in 4 pins for a month lug and play option? We can always make 4to5 pin harness I bought an agm replacement at Walmart and I paid 89, I would try to get a 12ah lfp and forget about that little one for good. ---

I just ordered a 10ah lfp for $35. Without power steering the 6ah should be fine, the 12v battery doesn’t do much. The nice part is you can’t hurt it and it should last for 10 years. LG ---

This is the type that may be 3s. Mine only charged to 12 volts. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/c/c03a1848fdbbcb406c2a4756dafb49073ff31695.jpeg) Bigger one, ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/8/8aec105c2c5558ed456941f9ff688d5655d7a1f7.png)
