Lift Gen4 Full Range Battery

Build, Repair & Mod

Hi all,

First post and I’ve been reading through some older threads on opening Lifts battery due to my Gen4 battery dying.
“Charged battery from 75% to 100% went out on the lake. 10 mins later:
Remote showing “Over Current”
Brought it back in and getting these lights on the battery after turning it off and on (see pics). Did a battery reset, no change. Same colors when plugging into the charger.
Lift v4”
Lift replaced the battery under warranty and did not want the broken battery back. So I opened it up. Here are some pictures for those interested.

Relay HFZ16V-100/900-12

So far all the cells check out and are balanced at 4.02v

I’m guessing the BMS went bad but will be checking the Relay here soon.

Is that glue residue all over the case edge?

7

Hardened plastic. Case comes sealed. Had to cut it open. I wasn’t too concerned about keeping it clean or resealable.

Ah, the lift glue is brittle and easy to break. I would imagine it’s the same with the v4 and the right tools.
