I have installed a 22 cell (92v) battery built by David Bissen and am having great success. While the setup is still very new, and the permanent installation is not finalized, I wanted to begin the documentation for other Think owners that may be interested in replacing their AGM and upgrading to a lithium battery setup. As a background, my old battery setup would allow me to go a couple of miles, which while fine to get to the beach and back, limited me to staying close to home. I wanted to be able to easily go 15 miles without worrying about the battery. I believe I have a lot more… In terms of fit and finish, the battery pack easily fits in the stock location under the front seats. I am in the process of fabricating a battery tie down and will use the factory bolt holes. I will also likely add fans to the case, but so far this has not proven to be necessary. Currently I have sent my charger to Dave to reprogram the charger so I can get a full 92v charge. The charge profile I was using only took the cells to 84v, but that was a HUGE improvement over the AGM setup. Acceleration feels faster (maybe less weight, maybe placebo), but the speed is still governed at 25 mph :(…The cart drives fine and I have been able to drive the cart into and around town and back without any issue (other than limited top speed). The furthest I have driven the cart is ~ 6+ miles and voltage dropped from ~83v to 80v. Ideally, I could reprogram the controller to allow the cart to drive faster. Maybe I should consider changing the gear ratio so I can go a tad faster without spinning the motor too fast? While 35 mph would be nice, 45mph would be nicer :). Pictures and updates to follow… My next modification will be installing disc brakes… ---

I’d really like to see pictures of your final install. I’ve been toying with this as well. ---

I’ll post pictures shortly…I would HIGHLY recommend going through David (vs. importing from a Chinese seller) as you will likely need support… ---

@cij got a drop in kit. I also sell the bare cells for diy, $100 each. Use 20-24 for 72v to 88v. 94ah or double up for 188ah. These are new real ev batteries in current use, not lifepo4. In stock, 1 week delivery with support. ![samsung 94ah cells](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/f/fc4dfd36e9aeb10041429f919e8bf80f3bd50ddf.jpeg) ![SDI 94ah size](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/c/c2bcd1a691cba4f87eb1a65ee616b27282a110a9.jpeg) ---
